Fast shipping and well packaged
Arrived earlier than expected. Packaging protected the flanges from damage during transit. Would order again.

Good fit and finish
Dimensions were accurate according to the spec sheet. Slightly tight fit initially but seated properly after installation.

No oil needed
Perfect for our dry environment where oil contamination is a concern. The graphite plugs are well embedded.

Excellent for high load applications
Used these in a conveyor system modification. The self-lubricating feature works as advertised and reduced maintenance time significantly.
