Product Description
CMT Bearing 19mm - 8mm is a precision replacement bearing designed to restore smooth, self-guiding performance to CMT router bits. Built from steel, this guide bearing fits flush trim, pattern, rabbeting, and profile bits, giving woodworkers a reliable way to keep their router bit collection performing accurately along template and workpiece edges.
Key Features
- Steel construction - provides durable, long-lasting performance that holds up to repeated use on router tables and handheld routers alike.
- 3/4 in. outer diameter - matches the geometry of compatible CMT router bits, ensuring a precise fit without wobble or play.
- 8mm bore diameter - sized to seat correctly on the bit shank, maintaining accurate alignment during routing operations.
- 6mm plate thickness - a compact profile that keeps the bearing low-profile and properly positioned relative to the cutting edge.
- 14.29mm cutting depth dimension - gives you the clearance needed for consistent, full-depth guided cuts along template edges.
- Black shield orientation matters during reassembly - the shield must face the correct direction to correspond with bearing rotation, protecting internal components and extending service life.
Why This Product
- Worn or seized guide bearings cause chatter, uneven edges, and scorch marks - replacing the bearing with this exact-spec part restores clean, smooth guided cuts without replacing the entire router bit.
- The 8mm bore and 3/4 in. outer diameter are matched to CMT router bit specifications, eliminating guesswork when sourcing a replacement for flush trim, pattern, or rabbeting applications.
- Steel construction means the bearing can handle the heat and friction generated during extended routing sessions on a router table or with a handheld router.
- A simple, low-cost replacement component - swapping the bearing instead of the full bit is a practical, economical maintenance approach for any router bit collection.
