Good but packaging
Bearings are smooth and seem durable. Only giving 4 stars because the outer box was slightly dented during shipping, though the product was fine.

Excellent Quality
Used the 6308 model for a lathe repair. The bearing fits perfectly and runs very smoothly without any noise. Highly recommended for industrial use.

Fast Delivery
Arrived earlier than expected. The bearing was well protected in individual packaging. Great value for the price.

Perfect Replacement
Fit my electric motor shaft perfectly. The RS seal keeps dust out effectively. Very satisfied with the performance so far.
Q: What is the inner diameter of the 6309 model?
A: The 6309 bearing has an inner diameter (ID) of 45mm, an outer diameter (OD) of 100mm, and a width of 25mm.
Q: Can I use RS seals instead of ZZ shields?
A: Yes, RS rubber seals provide better protection against dust and moisture compared to ZZ metal shields, but may have slightly higher friction.
Q: Do you ship each bearing individually?
A: Yes, each bearing is packaged individually in a box to prevent damage during transit, even when ordering multiple units.
Q: Is this suitable for high speed applications?
A: These are standard precision P0 bearings suitable for typical industrial motor speeds. For extremely high RPM, please consult technical specs.
Q: What type of grease is used for lubrication?
A: The bearings come pre-lubricated with standard lithium-based grease suitable for most general industrial applications.
