Perfect for high heat applications

Used these in a dryer assembly mechanism. No oil needed and they handle the heat well.

Hard to install without tools

Product is good but tight fit required reaming. Make sure you have the right tools.

Good quality, slow shipping

Bearings are great quality but took a week to arrive due to custom sizing.

5 FAQ
