Description
NSK S6900ZZ — genuine NSK Stainless Steel Deep Groove Ball Bearing (model S6900ZZ). Specification: S6900ZZ (SUS440).
Check the suffix before ordering. Open, ZZ and 2RS versions share the same dimensions but behave differently, and clearance (CN or C3) matters for motors.
Deep groove ball bearings are the most common bearing type, carrying radial load and moderate axial load at high speed. They are used in electric motors, fans, pumps, gearboxes and household and industrial machines.
Key Features
- Open types need external lubrication; ZZ and 2RS types come pre-greased
- Metal shields (ZZ) allow higher speed; rubber seals (2RS) keep dust out better
- Check bore, outside diameter and width against the shaft and housing
- Standard clearance is normal; C3 is for running hot or with tight fits
