SmalleySpirolox locking rings – VS and VSM

Spirolox retaining rings, also known as spiral retaining rings, are manufactured by winding a flat metal wire, rather than by drawing.

They are typically used to lock an assembly in translation, and are often used in fields such as aeronautics, automotive, medical technology, agriculture or the oil and gas industry.

Highly reliable, they are unlikely to come apart on their own.

Their manufacturing process offers several advantages:

Firstly, the product has no stamping burrs, making installation easier as there is no interference with adjacent assembly components.

Secondly, the double-turn ring allows support on a 360° holding surface.

The special feature of Spirolox VS and VSM retaining rings is that they are single-turn rings designed for light loads and shaft mounting. They are interchangeable with circlips conforming to international standards, e.g. DIN 971 and DIN 972. An equivalence list can be consulted.

VH ring dimensions are in mm and range from 6 to 3000mm.

VH ring dimensions are in inches and range from 0.25” to 10”.

Our range of stop rings includes over 6000 standard parts available in carbon steel, 302 or 316 stainless steel. However, if your application has special requirements, such as diameter, bending, material used, ring size, finish, ends or even the winding direction of the stop ring, specific ring designs are possible, without tooling costs.

Similarly, prototypes can be produced quickly for large or small volume orders, and adjustments to designs can easily be made throughout the production process.
