This GE40ES-2RS spherical plain bearing is made of carbon steel and has double seals. It has a 40 mm inside diameter, a 62 mm outside diameter, and a 28 mm depth. This spherical plain bearing has a wide race cross-section for applications that support high misalignment adjustment. This bearings inner and outer races are made of carbon steel for durability and resistance to deformity under heavy loads. Rubber seals on both sides of the bearing keep the lubricant in and contaminants out.
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 rolling 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.
