Perfect replacement for lathe spindle
Ordered the 6405 ZZ model. Fits perfectly and runs very smoothly with minimal noise. Great quality for the price.

Reliable for motor repair
Used the 6406 RS on an electric motor rebuild. No overheating issues after 50 hours of continuous run time.

Good quality, standard spec
These bearings are solid for general industrial use. Not premium ceramic, but exactly what was needed for the repair job.
Q: Are these bearings metric or inch sized?
A: These are standard metric deep groove ball bearings following ISO dimension standards.
Q: Can these bearings be regreased?
A: ZZ shields are non-removable. RS seals are generally sealed for life, though some variants allow regreasing. Please check specific sub-model details.
Q: Do you offer bulk discounts for the 6408 model?
A: Yes, please contact our sales department directly for pricing on orders exceeding 50 units.
Q: What is the maximum operating temperature?
A: Standard grease allows operation up to 120 degrees Celsius. Higher temperatures require special lubrication.
Q: What is the difference between ZZ and RS seals?
A: ZZ indicates metal shields on both sides which reduce friction, while RS indicates rubber contact seals which offer better protection against dust and moisture.
