Exactly what I needed

Fit perfectly on the 20mm shaft. The self-lubricating feature saves me a lot of maintenance time.

No maintenance required

Love the self-lubricating aspect. Installed them in a hard-to-reach spot and no grease needed.

Industrial grade quality

Using in conveyor system application. They handle the load well and show no signs of wear yet.

Good value

Works well but the fit was slightly tight initially. Once seated, it operates smoothly.
