The S99GLZM2540058 is an open-series linear plain bearing with a 25 mm bore and 40 mm outer diameter, featuring an anodized aluminum housing and a J® polymer liner for maintenance-free, self-lubricating operation. It supports shafts with a hard anodized aluminum finish of 8-16 RMS surface roughness and operates continuously from -14°C to +90°C, with intermittent use up to +120°C. The bearing dimension tolerance for the housing bore is +0.091/+0.030 mm, and it has a length of 58 mm, groove width of 14.5 mm, and groove depth of 1.85 mm. Dynamic load capacity at 0° is 815 kgf and static load capacity is 5704 kgf. Secure mounting is achieved with set screws (not included).
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.
