This Sealmaster SBG-SA Series two-piece spherical plain bearing is unsealed and is suitable for use in a mounted housing to accommodate pivoting and angular misalignment, such as in bearing connectors at the ends of hydraulic cylinders and mechanical shock arrestors. This bearing's one-piece race is manufactured from heat-treated ASTM International 4130 carbon steel for wear resistance and is coated for corrosion resistance. The alloy steel ball is heat treated and chrome plated for wear resistance, and a lubrication groove and hole on its inner diameter facilitates lubrication from the shaft to the bearing. The race's inner and outer surfaces are precision ground to maximize surface-to-surface contact, its outer surface edge is chamfered to ease installation into the housing, and its wide cross section provides high misalignment adjustment. This spherical plain bearing is suitable for use in pivoting and angular misalignment applications, such as in shock absorbers, industrial fans, packaging equipment, and hydraulic cylinders.
Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All roller bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
Sealmaster manufactures bearings and bearing accessories. The company, founded in 1938 and headquartered in Elsmere, KY, meets International Organization for Standardization (ISO) standard 9001.
