The S99APZM12F022032 is a precision Frelon-lined linear bearing with a 12 mm bore and 32 mm overall length, designed for high-load, low-friction linear motion applications. It features an anodized aluminum body and a bonded Frelon® liner, with a bore tolerance of +0.043/+0.016 mm and an outer diameter tolerance of 0/-0.018 mm. The bearing accepts a 19.4 mm wide retaining ring and a 6R11ML017525 O-ring, and supports a maximum load of 3950 N. It operates with a running clearance of approximately 0.025 mm, compatible with shaft finishes of 0.2-0.4 µm Ra and hardness of HRC 35 or higher. The liner dampens shock loads and vibration, provides consistent performance from -240°C to +260°C, and is self-lubricating, with optional lubrication reducing friction by up to 50%. The open series design includes a 7.6 mm slot with a 60° angle. Applications include washdown, high-load, cantilevered, and contaminated environments.
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.
