SKF 6218 TC/C78 Radial Bearing, Single Row, Deep Groove Design, ABEC 5 Precision, Open, Normal Clearance, Standard Cage, 90mm Bore, 160mm OD, 30mm Width

This SKF 6218 TC/C78 deep groove ball bearing is unsealed, has a standard cage, and has CN internal clearance. It has a 90mm ID, a 160mm OD, and a 30mm width. This single-row ball bearing has deep groove geometry for supporting radial and axial loads at high speeds. The CN (normal) radial internal clearance designation indicates it is for use in applications not involving thermal expansion or atypical precision. This bearing conforms to the Annular Bearing Engineering Committee (ABEC) 5 precision standard for performance within a narrow range of variation. It is open on both sides for lubricating in place The standard cage balances the load distribution by spacing the balls evenly and also prevents the balls from coming into contact with one another during use, reducing friction, vibration, and noise. This single-row deep groove ball bearing is suitable for use in applications including, but not limited to, transmissions, motors, and pumps, 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.SKF manufactures bearings, seals, and lubrication systems for automotive, energy, and other industrial applications. The company, founded in 1907 and headquartered in Gothenburg, Sweden, meets International Organization for Standardization (ISO) standards 9001 and 14001 and ISO/TS 16949.
