Product Description
CMT Bearing 19mm - 6mm by CMT is a precision steel replacement bearing designed to keep your router bits running smoothly and accurately. Whether you are restoring a worn guide bearing on a flush trim bit, a pattern bit, a rabbeting bit, or a profile bit, this bearing delivers reliable self-guiding performance against templates and workpiece edges. With a 3/4 in. outer diameter, 6mm bore, and 6mm plate thickness, it is engineered to fit CMT router bit configurations that require this exact size - making it a direct solution for maintaining cutting accuracy on the router or router table.
Key Features
- Steel construction - provides the durability and rigidity needed to withstand the high-speed demands of router bit guiding, reducing wear and extending service life between replacements.
- 19mm outer diameter (3/4 in.) with 6mm bore - precise dimensional sizing ensures a proper fit on compatible CMT router bits, so you get consistent, accurate edge-following with no wobble or play.
- 6mm plate thickness - matches the original bearing profile on compatible bits, allowing a drop-in replacement without modifying the bit assembly.
- Black shield orientation matters during reassembly - the black shield must face the correct direction to correspond with bearing rotation, ensuring the bearing performs as intended after installation and preventing premature failure.
Why This Product
- A worn or damaged guide bearing causes drift, chatter, and inaccurate cuts - this replacement bearing restores the self-guiding precision your flush trim, pattern, rabbeting, and profile bits depend on.
- The 3/4 in. outer diameter and 6mm bore are specific to CMT router bit configurations requiring this exact size, making it the correct choice when you need an exact-spec replacement rather than an approximate fit.
- Steel construction means this bearing holds up under repeated, high-speed routing passes, giving you a cost-effective way to extend the usable life of your existing CMT router bits without replacing the entire bit.
- Replacing the guide bearing rather than the full bit is a practical maintenance strategy for both router table work and handheld router use - this bearing supports that approach with a precise, direct-fit design.

Frequently Asked Questions
What router bit types is this bearing compatible with?
This bearing is used as a guide bearing on flush trim bits, pattern bits, rabbeting bits, and profile bits that require a 3/4 in. outer diameter bearing with a 6mm bore and 6mm plate thickness.
Is there anything to watch for when reinstalling this bearing?
Yes - the black shield must be kept right side up to correspond with the correct bearing rotation direction during reassembly. Orienting it incorrectly can affect bearing performance and longevity.
What is this bearing made of?
This bearing is made of steel, which provides the strength and durability needed to handle the high rotational speeds involved in router bit guiding applications.
Can this bearing be used on a router table as well as a handheld router?
Yes. This replacement bearing is suitable for use with both handheld routers and router tables, wherever a compatible CMT router bit is being used.
