The S99GSPM2540058 is a closed linear plastic bearing with a 25 mm bore, designed for use with hard anodized aluminum shafts. It features a self-lubricating design that is resistant to corrosion and dirt, making it suitable for various applications where maintenance-free operation is desired. The bearing can operate continuously at temperatures ranging from -14¬8C to +90¬8C and can handle intermittent temperatures up to +120¬8C. It is important to note that while the bearing is compatible with other materials such as stainless steel and chrome plated steel, the service life may be affected if the hardness is below HRC 50 or if the surface finish deviates from the recommended 8-16 RMS. The bearing is secured by a retaining ring, which is not included. The product is lightweight and provides vibration dampening, making it a practical choice for applications requiring reliable performance.
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.
