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 against 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 is a ZZ bearing the preferred choice?

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

Can the 6204 ZZ PPL replace other standard 6204 ZZ bearings?

Yes. The standardized dimensions of 20x47x14 mm allow it to replace compatible 6204 ZZ bearings when the original equipment specifications are identical.
