No maintenance required
Perfect for sealed units where oiling is impossible. Saves me a lot of time on maintenance.

Good value pack
The quality is consistent across the different sizes. One bushing was slightly tight but fit after reaming.

Excellent for small motors
Used the 4mm bushing for a DC motor mount. Very smooth operation and no squeaking after weeks of use.

Durable material
Withstands moderate vibration well. Would prefer a larger pack option for industrial use.
