The S99APZM25F040058 is a precision Frelon-lined linear bearing with a 25 mm bore and 58 mm overall length, designed for high-load, low-friction applications. It features an aluminum body with an anodized finish and a bonded Frelon® liner, providing self-lubricating operation and tolerance for contaminants, vibration, and shock loads. The bearing supports a maximum dynamic load of 14935 N, operates within a temperature range of -240°C to +260°C, and is rated for a maximum PV of 214 kgf/cm²·m/min. It requires a shaft finish of 0.2 to 0.3 µm Ra and hardness of HRC 50 for optimal performance. The part belongs to a series that permits open or closed configurations, with this variant identified as open. Recommended lubricants include 3-in-1 oils or petroleum-based greases; PTFE-based products are prohibited.
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.
