SKF Single Row Deep Groove Ball Bearing 20 mm ID, 52 mm OD, 15 mm Wide, Sealed Sheet Metal Cage 6304-2RSHNR

SKF 6304-2RSHNR is a single row deep groove ball bearing engineered for industrial environments requiring reliable rotational support. This bearing features a 20 mm inside diameter, 52 mm outside diameter, and 15 mm race width with a sealed construction that safeguards internal components from dust and debris.

Constructed with hardened steel balls and races, along with a low-mass sheet metal cage, the bearing reduces frictional losses and withstands cyclic loading for prolonged service life. It supports radial loads and moderate axial loads, making it suitable for a wide range of applications.

The seal design maintains lubrication and prevents contamination ingress, enabling maintenance-free operation even under continuous or high-speed use up to 9,500 rpm. Its cylindrical bore allows direct mounting on accurately sized shafts without additional adapters.

Typical use cases include compact motor spindles in automation systems, small electric motors in electronic devices, gearbox input shafts for industrial drives, and conveyor idler rollers in production lines.

Supports dynamic loads up to 16.8 kN for enhanced durability. Static load capacity of 7.8 kN suitable for start-stop or stationary conditions. Sheet metal cage design improves rotational stability. Internal clearance CN ensures precise shaft positioning.

Designed to operate at high speeds up to 9,500 rpm. Sealed end type minimizes contamination ingress. This SKF bearing series is well-suited to industrial, manufacturing, automation, and machine-building sectors where robust, compact bearings with reliable sealing are essential.
