NSK 6000ZZ Shielded Deep Groove Ball Bearing 10 x 26 x 8 mm
Available
This NSK range covers 5 single row deep groove ball bearings with two metal shields (ZZ): the 6000ZZ, 6201ZZ, 6003ZZ, 6905ZZ and 6906ZZ, from 10 to 30 mm bore and 26 to 47 mm outer diameter. Select the size from the drop-down: each size has its own bearing number, dimensions, load ratings and limiting speed in the Model Details.
Deep groove bearings are the most widely used ball bearing type. They carry radial loads and axial loads in both directions, run at high speed and need no adjustment. The two metal shields (ZZ) hold the grease in and keep larger particles out without adding seal friction.
Where this product is used
- Electric motors, pumps and fans
- Conveyors, gearboxes and general machinery
- Power tools and appliances
Features
- Two metal shields (ZZ) hold the grease in and keep larger particles out without touching the inner ring, so friction stays low and speed capability high
- Basic dynamic load ratings 5.05 to 7.95 kN and static load ratings 1.97 to 5 kN across the range
- Limiting speeds of 14,000 to 30,000 rpm on grease, depending on size

Selecting the right option
Metal shields (ZZ) retain the grease and keep larger particles out without touching the inner ring, so friction stays low and speed capability high. A shield is not a seal: fine dust and moisture can still enter, so choose a contact-sealed bearing where dust, splashes or damp are present.
Fitting and use
Check the load and speed against the figures for your size before ordering and apply a suitable safety factor. Deep groove bearings must always carry a minimum radial load so the balls roll rather than slide, and heavy axial loads should be checked with AIMS before ordering.
Press on the ring that is being fitted, not the other ring or the balls: force goes through the side face of the inner ring on a shaft and through the outer ring in a housing.
Shielded bearings are lubricated at the factory and built for inner ring rotation. Do not wash them or heat them before mounting, and do not rely on them for high speed outer ring rotation.
