The S99APZM08F016025 is a precision Frelon-lined linear bearing with an 8 mm bore and 25 mm length, designed for self-lubricating, high-load applications. It features an anodized aluminum body and a bonded Frelon® liner, with a bore tolerance of +0.035/+0.013 mm and an outer diameter tolerance of 0/-0.021 mm. The bearing supports a maximum load of 2055 N, operates at continuous speeds up to 70 cm/sec (or 200 cm/sec intermittently), and functions in temperatures from -240°C to +260°C. It is suitable for environments with dust, moisture, or shock loads, and recommends a shaft finish of 0.2-0.4 µm Ra and minimum HRC 35 hardness. The part is part of a series that uses retaining rings and O-rings for installation, and requires petroleum-based lubricants, not PTFE or silicone products.
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.
