A precision Frelon-lined linear bearing with a 20 mm bore and 45 mm overall length, designed for low-friction linear motion in high-load, contaminated, or extreme-temperature environments. The bearing has an aluminum body with an anodized finish and a bonded Frelon® liner, and is self-lubricating. It supports a maximum load of 9265 N, operates with a maximum PV of 214 kgf/cm²·m/min, and tolerates temperatures from -240°C to +260°C. Recommended shaft finish is 0.2 to 0.3 µm Ra at HRC 50 hardness. The bearing accepts cantilevered loads with a maximum 2:1 ratio and is compatible with petroleum-based lubricants. It features an open design with a 10.8 mm slot, 10 mm slot width, and 28 mm retention hole spacing. No corrosion, seizure, or catastrophic failure occurs under normal operating conditions.
A bearing is a device that reduces friction between moving components by preventing metal-to-metal contact while assisting components (shafts, axles, and wheels) to freely rotate around a fixed axis, cutting down on heat generation and the amount of energy that is consumed. By replacing sliding motion with low-friction rolling motion, the life of the rotating components is increased. A bearing also keeps the shaft in the proper position, providing support and alignment and transferring the axial or radial loads to the housing.
The types of bearings that we offer include rolling element bearings, which consist of both ball bearings and roller bearings.
Balls are utilized as the rolling element in ball bearings; a retainer holds the balls in place and allows them to freely rotate. The balls are kept inside channels cut in both the inner and outer races. Because there is no surface contact between the balls and races, precision ball bearings have a lower load capacity for their size than other bearings.
