SKF 6209-2RS1/C4 Radial Bearing, Single Row, Deep Groove Design, ABEC 1 Precision, Double Sealed, Contact, C4 Clearance, Steel Cage, 45mm Bore, 85mm OD, 19mm Width

This SKF 6209-2RS1/C4 deep groove ball bearing is double sealed, has a steel cage, and has C4 internal clearance. It has a 45mm ID, an 85mm OD, and a 19mm width. This single-row ball bearing has deep groove geometry for supporting radial and axial loads at high speeds. The C4 radial internal clearance designation indicates that the radial slack between the inner and outer rings is greater than the standard CN (normal) and C3 clearances to allow for thermal expansion. This bearing conforms to the Annular Bearing Engineering Committee (ABEC) 1 precision standard for performance within a narrow range of variation. Rubber seals on both sides of the bearing keep the lubricant applied at manufacture in and contaminants such as dirt and grime out. The steel 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.

• Single-row deep groove geometry for high speeds and supporting both radial and axial loads
• C4 radial internal clearance for radial slack between the inner and outer rings that is greater than CN (normal) and C3 to compensate for thermal expansion
• Conforms to ABEC 1 precision standard
• Rubber seals on both sides of the bearing to keep lubricant in and contaminants out
• Steel cage evenly spaces the balls for even load distribution and prevents contact to reduce friction, vibrations, and noise
