This Sealmaster FLBG Series three-piece spherical plain bearing is unsealed and corrosion resistant, and is suitable to accommodate pivoting and angular misalignment, such as in light-duty hydraulic cylinders that come in contact with chemicals or water that is acidic or alkaline. This bearing has a carbon steel outer housing with a larger outside dimension than other precision spherical plain bearings and is not dimensionally interchangeable with other spherical plain bearings. This bearing's carbon steel outer housing is coated for corrosion resistance, its one-piece bronze race is low friction, and the alloy steel ball is heat treated and chrome plated for wear resistance. The race's inner and outer surfaces are precision ground to maximize surface-to-surface contact, lubrication grooves and holes direct grease into the bearing, 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 light-duty pivoting and angular misalignment applications in corrosive environments, such as in bottling equipment and mining machinery.

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.
