💡 What is a needle roller bearing adapter sleeve used for in linear slide units?
An adapter sleeve is used to adapt a tapered bore to a straight shaft so bearings stay seated and aligned.
- Helps mount needle roller inserts and sealed ball bearing cartridges in tight linear slide unit assemblies.
- Provides accurate shaft fit and concentricity for gearbox, transmission, and shaft adapter applications.
- Works with a variety of materials, including ceramic or high carbon steel bearings, and shell-type adapters.
