The S99APCM25F040058 is a precision Frelon-lined linear bearing with a 25 mm bore and 58 mm overall length, designed for high-load, low-friction applications. The bearing body is made of anodized aluminum with a bonded Frelon liner, offering self-lubricating properties and operation across a temperature range of -240°C to +260°C. It supports a maximum load of 14935 N and a maximum PV value of 214 kgf/cm²·m/min. The recommended shaft finish is 0.2 to 0.3 µm Ra with a hardness of HRC 50. The bearing accommodates cantilevered loads with a maximum 2:1 ratio and can operate at up to 70 cm/sec continuously or 200 cm/sec intermittently without lubrication. Lubrication with petroleum-based oils or greases reduces friction by up to 50% and extends life. It is compatible with retaining ring M25F040058 and O-ring 6R11ML035525.
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.
