TREND Bearing 21mm diameter 1/4" bore | B21

Trend B21 Bearing (21mm diameter, 1/4" bore) for guided routing

The Trend B21 bearing is a guided router cutter bearing designed to help the cutter follow a template or workpiece edge for controlled profiling. With a 21mm outside diameter and a 1/4" (6.35mm) bore, it’s suited to maintenance or replacement on compatible cutter assemblies where a bearing guide is required.

Built for workshop and site use, the B21 features shielded construction to help resist dust ingress and is grease packed for life, supporting smooth running during routing tasks.
