The S99APZM30F047068 is a precision Frelon-lined linear bearing with a 30 mm bore and 68 mm overall length, designed for high-load, low-friction applications in contaminated or extreme-temperature environments. It features an anodized aluminum body with a bonded Frelon® liner, offering self-lubricating operation and a load capacity of 21010 N. The bearing supports a maximum PV limit of 214 kgf/cm²·m/min and operates between -240°C and +260°C. It is open-ended, with a retaining ring slot and dimensions matching the series: outer diameter 47 mm, slot width 14.2 mm, and slot angle 72°. Recommended shaft finish is 0.2-0.3 µm Ra with HRC 50 hardness.
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.
