Product Description
CMT Bearing 16mm - 8mm by CMT is a precision steel replacement bearing designed to keep your router bits guiding smoothly and accurately along templates, workpiece edges, and patterns. With a 16mm outer diameter and an 8mm bore, this router bit guide bearing fits a range of CMT profile, flush trim, rabbeting, and pattern bits - restoring clean, consistent cuts when worn or damaged bearings compromise your results.
Key Features
- Steel construction - provides the durability and strength needed to handle repeated contact with workpiece edges and templates under routing loads.
- 16mm outer diameter - determines the offset between the cutting edge and the guide surface, so matching this dimension to your original bearing preserves the correct cutting profile and rabbet depth.
- 8mm bore diameter - designed to seat precisely on the router bit shank for a secure, wobble-free fit that keeps cuts true.
- 5mm plate thickness - a slim profile that positions the bearing correctly within the bit assembly without interfering with cut depth or bit geometry.
- Black shield orientation matters - the black shield must face the correct direction to correspond with bearing rotation during reassembly, ensuring proper function and longevity after replacement.
Why This Product
- Restores accurate self-guiding performance on flush trim, pattern, rabbeting, and profile bits when the original bearing wears out - saving the cost of replacing the entire bit.
- The precise 16mm x 8mm x 5mm dimensions make this a direct-fit replacement for compatible CMT router bits, eliminating guesswork during maintenance.
- Steel construction holds up to the repeated edge contact that bearing-guided routing demands, making this a reliable long-term maintenance component.
- A cost-effective way to extend the service life of your CMT router bit set by swapping a single bearing rather than discarding otherwise sharp carbide cutters.

Frequently Asked Questions
Does it matter which direction the black shield faces when I reinstall this bearing?
Yes - the black shield must be kept right side up to correspond with the bearing rotation during reassembly. Installing it in the wrong orientation can affect bearing performance and longevity.
What are the exact dimensions of this bearing?
The outer diameter is 16mm, the bore (inner) diameter is 8mm, and the plate thickness is 5mm. Confirm these match your existing bearing before ordering to ensure a proper fit.
What types of router bits is this bearing used with?
This bearing is used as a guide bearing on flush trim bits, pattern bits, rabbeting bits, and profile bits where the bearing rides along the edge of a template or workpiece to control the cut.
What is this bearing made of?
This bearing is made of steel, providing the strength and durability needed for repeated contact with templates and workpiece edges during router bit guided cuts.
