The S99APCM12F022032 is a precision linear bearing with a 12 mm bore and 32 mm overall length, designed for low-friction linear motion in high-load, contaminant-prone, or extreme-temperature environments. It features an anodized aluminum body with a bonded Frelon® liner, providing self-lubricating operation without corrosion or seizure. The bearing supports a maximum dynamic load of 3950 N, operates with a running clearance of approximately 0.025 mm, and maintains consistent performance across a temperature range of -240°C to +260°C. Recommended shaft finish is 0.2 to 0.3 µm Ra with a hardness of HRC 50 for optimal life. The design accommodates cantilevered loads up to a 2:1 ratio and allows for additional lubrication to reduce friction and extend service life. It is applicable in washdown, high-vibration, and dusty 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.
