The S99GLPM254058 is a closed-series linear plain bearing with a 25 mm bore, designed for maintenance-free operation with hard anodized aluminum shafts. It features an anodized aluminum body and a J® polymer liner, offering corrosion and dirt resistance, vibration dampening, and continuous operating temperatures from -14°C to +90°C. The bearing has a length of 40 mm, a groove depth of 43.7 mm, and a dynamic load capacity of 3625 N and static load capacity of 25372 N. It requires a retaining ring MD0471MQB040 and is intended for shaft surface finishes of 8-16 RMS.
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.
