When building or repairing machinery, we often take the smallest fasteners for granted. Standard circlips and retaining rings usually require a pre-machined groove on a shaft to sit correctly. But what happens if you cannot machine a groove? Or what if doing so blows past your production budget?
Enter the M1440 Grip Ring series, a specialized line of self-locking, axially fitted metric circlips designed specifically to provide strong retention on shafts without pre-machined grooves. By relying purely on frictional grip and high radial pressure, these unassuming components act as a powerful fastening alternative across countless industrial applications.
What Makes the M1440 Grip Ring Unique?
Unlike a standard DIN 471 external circlip that relies on a channel to hold its place, the M1440 series is engineered with a large section height. This design results in massive gripping pressure applied directly to the surface of the plain shaft.

Seated in Groove Frictional Grip
A major engineering benefit of the M1440 design is its tapered section. When fitted, this taper ensures even contact distribution around the entire circumference of the shaft. Because the ring is not stretched beyond its elastic limit during installation or removal, it can be re-used multiple times without losing its gripping force or damaging the shaft.
You will find M1440 grip rings quietly doing heavy lifting behind the scenes across a vast range of sectors:
- Automobile Assemblies: Securing lightweight linkages and pivot pins where structural machining is impractical.
- Industrial & Manufacturing Machinery: Acting as quick-fix or adjustable retaining stops on automated conveyor lines and guide rods.
- Office & Domestic Furniture: Holding rotating wheels, casters, or small internal hinges firmly in place on plain steel pins.
