Standard Flanged Ball Bearings SF6902ZZ

Standard Flanged Ball Bearings SF6902ZZ

The SF6902ZZ is a compact flanged ball bearing with a 15mm bore and 28mm outer diameter, measuring just 7mm in width. Its stainless steel construction offers good corrosion resistance, while the chrome steel balls ensure smooth rotation.

The bearing handles radial loads up to 876 lbf and can spin at speeds up to 21,600 RPM. The shielded design helps keep contaminants out while maintaining easy access for lubrication.

With its 30.5mm flange, this bearing stays securely positioned in assemblies. It’s suitable for temperatures from -30°C to 110°C and comes with ABEC-1 precision tolerances.

Ideal for small machinery or electrical motors where space is limited. The lightweight design (17.3g) makes it easy to handle during installation or maintenance. Compliant with RoHS and REACH standards.
