Good bearings, slow shipping
The 6310 bearings fit perfectly and perform well. Only complaint is the delivery took a bit longer than expected.

Exact replacement
Matched the specs for my compressor perfectly. The 2RZ seals keep dust out effectively.

Low vibration
Using the 6309 in a high-speed spindle application. Very little vibration even at max RPM. Highly recommended.
