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.

Excellent for motor repair

Replaced the bearings in my industrial fan with the 6312 model. They run very smoothly and noise levels are significantly reduced.
