This 6318 ball bearing has a chrome steel cage and races, and is open on both sides. It has a 90 mm inside diameter, a 190 mm outside diameter, and a 43 mm depth. The bearing has deep groove geometry for supporting both radial and axial loads and high speeds. The races are made of chrome steel for durability and resistance to deformity under heavy loads. The bearing meets the Annual Bearing Engineering Committee (ABEC) 1 standard for tolerances. The bearing is open on both sides for lubricating in place. The static load rating is 107,000 newtons and the dynamic load rating is 143,000 newtons. A chrome steel cage spaces the balls for even load distribution and prevents contact to reduce friction, vibration, and noise. The maximum speed with oil lubrication is 4,300 revolutions per minute (rpm). This deep groove ball bearing is used in applications such as electric motors, compressors, and material handling equipment, among others.

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.
