The S99NH2MBN0609 mount bearing is designed for use on hardened shafts ranging from 3 mm to 25 mm in diameter. It features a low-profile, lightweight caged design that allows for significantly higher speeds,Äîup to three times that of uncaged bearings,Äîwhile maintaining low rolling friction and high lubrication capacity. The bearing is constructed with a roller cup made of case-hardened steel, needle bearings made from 52100 hardened chrome steel, and a bearing cage of low carbon steel. To ensure optimal performance, the shaft surface must have a minimum hardness of HRC 58, or an inner race should be used over a softer shaft if available. The recommended housing tolerances for steel or cast iron are according to N6, while light metal should use tolerance R6. The bearing supports high load capacities, with dynamic load ratings reaching up to 11,000 N and static load ratings up to 15,200 N, making it suitable for applications requiring durability and reliability under high-speed conditions.
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.
