The applications

 

Civil Engineering Machinery Applications
Self - lubricating bearings with impact and dust resistance are ideal for civil engineering machinery. They solve lubrication issues, cut running noise, and extend bearing lifespan, especially in harsh mining and outdoor settings. Widely used in excavators' lift arms, undercarriage wheels, and hydraulic cylinders.

Application of new energy equipment

Featuring weather resistance, high load capacity, and self - lubricating maintenance - free properties, these bearings showcase their superiority in challenging refueling scenarios like outdoors, high altitudes, and underwater. General rolling bearings are restricted when exposed to the outdoors without timely maintenance, but self - lubricating bearings can effectively address such issues. They are, for instance, applied in wind and solar power stations.

Automotive Applications

Self - lubricating bearings, with their lightweight design, low - noise operation, and oil - free characteristics, have been rapidly promoted for automotive applications. They are constantly replacing needle roller and powder bearings, giving rise to new applications. These bearings not only support parts on the shaft but also prevent shaft deviation or jamming within the movable range. Additionally, they reduce friction and damage to parts during operation.
