FAQ

What does the ZZ designation mean?

The ZZ suffix indicates that the bearing is equipped with metal shields on both sides. These shields retain grease while protecting the bearing from dust and larger airborne contaminants without contacting the inner ring.

Is the bearing supplied pre-lubricated?

Yes. The bearing is factory-filled with grease and is ready for installation without additional lubrication under normal operating conditions.

When should a ZZ bearing be selected instead of a 2RS bearing?

ZZ bearings are recommended for clean or moderately dusty environments where lower friction, higher rotational speed and efficient heat dissipation are more important than maximum sealing performance.

Can the 6004 ZZ PPL replace other standard 6004 ZZ bearings?

Yes. The standardized dimensions of 20x42x12 mm allow it to replace compatible 6004 ZZ bearings when the original equipment specifications are identical.
