First of all, the linear bearings we understand are widely used in the machinery industry, but what we don't know is that linear bearings are now more and more widely used in precision equipment or special machinery industries. For example, electronic equipment, robots, automobiles and digital three-dimensional coordinate measuring equipment. That is to say, the role of linear bearings is getting bigger and bigger, and its prospects are immeasurable.

Secondly, we all know the application of linear bearings. Let us now understand the maintenance of linear bearings. The maintenance of linear bearings is divided into two categories, one is the maintenance of metal linear bearings, and the other is the maintenance of plastic linear bearings. For the former, the main use is lubrication and friction. Specifically, the linear bearing is injected with anti-corrosion oil and air-dried. Add grease later. Shaft lubrication can be supplied from the oil supply pipe or from the oil hole on the outer bearing housing. Since the sealing ring will scrape off the lubricating oil, oil lubrication is not suitable for non-porous bearings with sealing rings.

Plastic linear NACHI bearing material straight maintenance: because the sliding film inside the plastic linear bearing is made of self-lubricating plastic, it does not require additional oil supply and maintenance during use; and because the plastic linear bearing has a chip groove, Even if the bearing or shaft is packed with dust, there is no need to maintain it. The dust will automatically be taken out from the chip groove during the movement. Therefore, compared with metal linear bearings, plastic linear bearings are more convenient to care and maintain.
