The S99GLZM3047068 is a metric open-series linear plain bearing with a 30 mm bore and 47 mm outer diameter, featuring an anodized aluminum housing and a J® polymer liner for maintenance-free operation. It supports hard anodized aluminum shafts with 8-16 RMS surface finish, and operates continuously from -14°C to +90°C with intermittent capability up to +120°C. The bearing has a housing bore tolerance of +0.110/+0.040 mm, a length of 68 mm, groove width of 16.6 mm, and groove depth of 4.9°. It offers a dynamic load rating of 1146 kgf at 0°, 955 kgf at 90°, and 512 kgf at 180°, with static load ratings of 8025 kgf, 6684 kgf, and 3584 kgf respectively. 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.
