Product Description
CMT Bearing 1-1/4" - 1/2" by CMT is a precision replacement guide bearing designed for use with router bits in both handheld router and router table applications. This steel bearing keeps your router bit tracking smoothly along templates and workpiece edges, making it an essential component for flush trim work, pattern routing, rabbeting, and profile routing tasks. When a worn or damaged guide bearing causes drift or chatter in your cuts, swapping in a fresh replacement restores the clean, self-guided performance your bits were designed to deliver.
Key Features
- Steel construction - provides the durability and structural integrity needed to withstand the rotational forces generated during continuous router bit use, extending the working life of your bit setup.
- 1-1/4" outer diameter - matches the standard sizing used across CMT flush trim, pattern, rabbeting, and profile bit families, making it a reliable fit for a wide range of replacement applications.
- 12.7mm bore diameter (1/2") - sized to fit 1/2" shank router bits precisely, ensuring the bearing seats firmly without play or wobble that could throw off your cut line.
- 8mm plate thickness - maintains the correct bit geometry and cutting height when the bearing is reinstalled, so your depth of cut and edge profile stay consistent.
- Black shield orientation requirement - the black shield must be kept right side up to correspond with bearing rotation during reassembly, ensuring correct bearing function and preventing premature wear from improper installation.
Why This Product
- A worn guide bearing is one of the most common causes of inaccurate flush trim and pattern routing results - replacing it with a correctly sized 1-1/4" steel bearing restores precise edge-following performance without replacing the entire bit.
- With a 12.7mm bore, this bearing is matched to 1/2" shank router bits, which are widely used in router table setups and heavier-duty handheld routing where stability and accuracy matter most.
- The defined plate thickness of 8mm means the replacement bearing restores the original geometry of your CMT bit, keeping your rabbets, profiles, and flush trim cuts exactly where they should be.
- For woodworkers using CMT router bits across multiple applications - from template routing to edge profiling - keeping a replacement bearing on hand eliminates downtime when a bearing fails mid-project.

Frequently Asked Questions
Does it matter which way 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 result in improper bearing function and accelerated wear.
What router bit shank size is this bearing compatible with?
This bearing has a 12.7mm bore diameter, which corresponds to a 1/2" shank. It is designed for use with 1/2" shank router bits.
What types of router bits use this replacement bearing?
This bearing is used as a guide bearing on flush trim bits, pattern bits, rabbeting bits, and profile bits. It is a replacement and upgrade bearing for CMT router bits in these categories.
Will replacing this bearing restore my original cutting dimensions?
Yes - because this bearing matches the original 1-1/4" outer diameter and 8mm plate thickness specified for compatible CMT bits, reinstalling it correctly restores the intended bit geometry and edge-guiding performance.
