Key Features & Benefits
- Precision-ground sealed bearing — smooth, consistent rotation keeps profile bits tracking true against the workpiece edge without chatter or drift.
- 1/2" OD suits a wide range of profile bits — check your bit's bearing seat diameter before ordering to confirm fit.
- 3/16" ID bore — fits the standard 3/16" pilot pin used on many Carbitool and compatible profile router bits.
- Easy field replacement — when a bearing wears or seizes, swap it out rather than replacing the whole bit.
- Keep bearings clean and lightly oiled — after use, clean in glue solvent and apply a light oil to maximise service life.
When to Use This Bearing
The TB11 is a direct replacement bearing for Carbitool profile and trim bits that use a 1/2" OD x 3/16" ID bearing. If your existing bearing is seized, worn, or running rough, replacing the bearing with a TB11 will restore accurate, chatter-free cuts at a fraction of the cost of a new bit. Always clean the bearing seat and check the retaining hardware before fitting a replacement.
Pro Tip: After routing in resin-heavy timbers or materials with adhesive, clean bearings immediately in acetone or glue solvent — dried glue in the bearing race is the most common cause of premature failure. A drop of light machine oil after cleaning will keep the bearing spinning freely.
