1. What is an INA bearing and what are its uses
Here are the different types of INA bearings and their uses:
INA Needle Roller Bearings
Needle roller bearings have a long history of success as tried-and-true machine components for the design of radially compact bearing arrangements with very high load-carrying capacities.
In the configuration, they now have a service life that is up to 50% longer.
INA Industrial Ball Bearings
National Precision Bearing provides support for the INA industrial ball bearing range.
Spindle bearings, angular contact ball bearings, deep groove ball bearings, four-point contact ball bearings, and other goods are available from INA.
INA Spherical Roller Bearings
Solid inner and outer rings, caged single-row spherical roller bearings, and assemblies of cylindrical rollers and cages are some of these parts.
The outer rings are made without any ribs or with hard ribs on both sides, whilst the inner rings have one or two stiff ribs or are made without any ribs. Because of the cage, the cylindrical rollers cannot collide.
Caged and cageless cylindrical roller bearings are available.
2. How is an INA bearing different from other types of bearings
INA bearing is different from other types of bearings when it comes to:
Their upgrades
The upgrades, which are a part of the performance upgrades for the INA branded product series, are distinguished by increased load ratings compared to standard goods, offering the products performance advantages over competing products.
Similar to how linear modules can replace previous linear modules with a four-row system one-for-one, linear modules are linear systems with additional drive units added.
Since the customer does not need to modify their devices, this is extremely simple for them. We take pride in offering this caliber of service, making sure that our clients can easily get the things they need whenever they need them.
Their expansions
Over time, the Schaeffler selection of linear bearings and guideway assemblies has expanded.
Following the debut of the double-row linear ball bearing system, four-row and six-row ball bearing systems, as well as roller-type linear bearings for heavy-load applications, were introduced.
Their advancement in designs
Schaeffler has made design advancements that are exceptional in the bearing industry.
The seals built into the end faces of the carriages of the four-row Schaeffler INA linear ball bearings are another design rolling element.
The rolling element systems are shielded from contamination by the seals on the bearing's end faces.
First to have corrosion-resistant coating
Additionally, Schaeffler was the first business in the world to apply a corrosion-resistant coating to the rails and carriages of linear systems.
This is a useful feature in food and beverage manufacturing facilities where there are frequently numerous water washdowns and spills.
Introduce rolling bearing grease
Schaeffler also introduced a rolling bearing grease that is approved for use in Halal and Kosher food processing applications in the past eight to ten years.
Therefore, the producer won't have to worry about the food becoming contaminated due to religious considerations in cases when there is a chance of grease leaking out of the bearing (which is quite unlikely).
We have given the bearings more room for lubrication by inserting extra grease channels near the raceways inside the carriages.
This aids in extending the re-greasing period so that the bearing will continue to function properly even if it is not re-greased frequently or at all.
Advantages of INA bearings also includes reduction in friction, up to 5% cut in energy consumption of the entire compressor compared with designs using maintenance-free plain bearings, has four different designs that can be combined with or without raceways, and has high level of material compatibility with coolants.
3. What are the benefits of using this type of bearing over other types available on the market today?
These are some of the benefits in using INA bearings over other types available on the market today:
When it comes to efficiency rate
The load ratings of INA needle roller bearings have been substantially boosted due to improved surface quality.
Compared to the prior needle roller bearing, the dynamic load rating may be raised by 13%.
The significantly increased load ratings result in bearings with superior performance, longer service lives, lower lubrication loads, decreased friction, and lower bearing temperatures.
The advantages of all of these advancements include improved price-to-performance and increased efficiency for your applications.
When it comes to their accuracy rate
Single-row or double-row devices with cages and needle roller bearing are called needle rollers and cage assemblies. To realize bearings with a small radial design envelope, needle roller and cage assemblies can be employed because their radial design height only varies with the diameter of the needle roller bearing. They are appropriate for fast speeds, have a high load carrying capacity, and are especially simple to fit. Great runout accuracy bearing arrangements are possible if the raceways are constructed with high geometrical accuracy.
Along with the shaft and housing tolerances, the needle roller type might have an impact on the radial internal clearance. A raceway that has been hardened and the ground is needed on the shaft and in the housing for needle roller and cage assemblies.
When it comes to their lubrication capacity
Drawn cup needle roller bearings come with open ends and either a full complement of needle rollers or a needle roller and cage combination.
Higher speeds than full complement designs are possible with bearings with needle roller and cage components.
With the most needle rollers and the high load carrying capacity within the smallest design envelope fully complements drawn cup needle roller bearings with open ends. Their use at high speeds is constrained, though.
When it comes to their designs
Some drew cup needle roller bearing designs have a closed end. Because of this, they work well for sealing off the shaft ends of bearing arrangements.
This guards the bearing against pollution and moisture and protects it from harm caused by rotating shafts.
The base is either smooth or lock-beaded, depending on the size (stiffened). Small axial guidance forces are attainable because of the base's profile.
When it comes to their production
Aligning needle roller bearings are made up of drawing outer cups, replaceable inner rings, outer rings with a spherical exterior surface, plastic support rings with a concave inner profile, and needle roller and cage assemblies.
When it comes to their precision machines
A precisely machined raceway is included in IR inner rings. Chamfers on the end face facilitate insertion into the bearing and guard against harming the seal lips.
Both inner rings and inner rings without lubricating holes are available for proven machine elements.
A ground raceway is present in LR inner rings. The edges are fractured, and the end faces are rotated. Compared to IR rings, these rings have wider tolerances.
They are thus appropriate for applications that permit wider width tolerances and less stringent axial runout requirements.
When it comes to their assemblies and washers
When it comes to a hardened and ground-running surface, it is required to have a raceway that has axial needle and cage assemblies.
With their low installation height and plastic or metal cages, this cage assembly is integrated with the rollers which are needed for the support.
Because they are punched, through-hardened, polished, and ready to use, axial bearing washers can be utilized as shaft or housing locating washers. When the surrounding machine part is not hardened yet stiff and exact in shape, these washers are ideal for use.
Thrust bearing washers with centering spigots, axial needle roller and cage assemblies, and axial needle roller and cage assemblies with axial needle roller bearings are all examples of thrust bearing washers with centering spigots.
They can be used in conjunction with needle roller bearings, drawn cup needle roller bearings, and open or closed-ended drawn cup needle roller bearings.
The running surface of the needle roller and cage assembly must be toughened and ground for proven machine elements.
4. What industries rely heavily on INA bearings for their operations?
There are some of the industries that rely heavily on using INA bearings for their operations:
Raceway industry
Bearings with stamped raceways have longer operating life than the basic design where both sides of it can be stamped to increase mounting security, has balls that are securely guided to improve load distribution and ball rotation for less slippage, has reliable lubrication due to oil reservoir in the raceway and less surface deformation and wear.
Machinery industry
For decades, INA has been the global market leader in bearing arrangement solutions for feed spindles, main spindles, rotary tables, and linear guiding devices for proven machine elements.
However, deep groove ball bearings components are no longer the main deciding criteria for these machine subsystems.
Food industry
For dependable performance around-the-clock, use strong bearings with corrosion protection and efficient seals that are frequently greased for life.
Our deep groove ball bearings have the essential advantage in terms of working life thanks to contemporary materials and surface coatings that are constantly being improved.
5. Why are these bearings considered a critical component in many industrial applications?
These bearings are considered a critical component in many industrial applications because machines and facilities operate more efficiently when rolling bearings have low friction properties.
This results in significant energy savings, which is the cause of the designs' quiet operation and small size which is the #1 priority in all of our goods.
We can reduce friction and wear even further thanks to our cutting-edge surface coatings.
Design solutions that give the extra cost-effectiveness that is so desperately needed are produced through close collaboration with our customers.
Throughout this process, on-site expert counseling and a calculating service are always available.
6. How do you go about selecting the right type of INA bearing for your specific needs?
Before buying an INA bearing, consider the following factors:
-
The size, direction, and type of the bearing's load
When choosing bearings, the most crucial aspect to consider is load. Ball bearings can withstand mild to medium loads, but roller bearings can withstand larger loads.
When INA bearings are subjected to radial and axial strains at the same time, angular contact ball bearings or deep groove ball bearings are typically employed.
-
Space and location of the machinery occupied by the bearing
In mechanical design, the rolling bearing is often chosen based on the shaft size once the shaft size has been established.
-
Rigidity of the bearing
The amount of force necessary to cause a unit deformation of a bearing is referred to as its stiffness.
Although most machines do not need to take into account rolling bearings' extremely modest elastic deformation, bearing stiffness is a significant consideration in particular machines, such as machine tool spindles.
7. Where can you find reliable suppliers who carry this type of product?
You can find reliable suppliers who carry INA bearings at distributors in India.
They have many benefits, including being compact, affordable, and having a high load carrying capacity and a steady level of quality. Needle roller bearings from this brand are used in a wide variety of applications in numerous industries.
Conclusion
In addition to rolling bearings, the INA bearing arrangement also comprises parts that are related to bearings, like shafts and bearing seats.
In order for an oil-free bearing to perform to its maximum potential, corrosion and wear must be prevented by the lubricant, which is also a crucial component of the bearing configuration.
