Product Description
Best For
The 18C6-16 retaining ring secures the blade/knife shaft assembly on a straight knife cloth cutting machine, keeping the blade seated correctly through continuous cutting shifts.
What It Does
- Holds the knife shaft assembly in correct axial position
- Prevents shaft play that leads to uneven or wandering cuts
- OEM-spec direct fit — no modification needed
Use Cases
Garment factory cutting rooms running straight knife cutters (5″–12″ blade sizes) keep this ring as a maintenance spare for scheduled blade servicing or when shaft play develops.
Benefits
A worn or missing retaining ring lets the knife shaft shift slightly during cutting, which shows up as an uneven cut edge or a blade that feels loose in the housing. Replacing the ring restores the tight shaft fit the cutting action depends on — and it’s a small, inexpensive part next to the cost of a full shaft assembly.

How to Use
First, power down and unplug the cutting machine before accessing the blade shaft. Next, remove the old or damaged retaining ring using retaining-ring pliers. Then, fit the 18C6-16 into the same shaft groove, seating it fully so it sits flush. Finally, hand-check the shaft for play before restoring power and test-running the machine.
FAQ
Buyer Intent
Q: What are the signs my retaining ring needs replacing?
Blade shaft play you can feel by hand when the machine is off, or a cut edge that’s becoming visibly uneven despite a sharp blade, both point to a worn or failed retaining ring.
Compatibility
Q: Does this fit all straight knife cutter blade sizes (5″ to 12″)?
It’s specified for the standard straight knife cutting machine shaft assembly used across the 5″–12″ blade range in this category, but confirm your machine’s exact shaft diameter against the part spec before ordering.
