SmalleyExpanding Rings – FS/FSE

FS and FSE expanding rings

FS and FSE expanding rings, also known as Snap-Rings, are square-edged, single-turn rings with a gap.

The special feature of FS and FSE expanding rings is that they are heavy-duty rings that can withstand very high forces and loads.

They are mainly used to lock an assembly in translation and are often used in fields such as the automotive industry.

However, they can also be used in the event of repeated impacts.

Smalley’s FS and FSE expanding rings are designed for shaft mounting.

A high-quality manufacturing process

FS and FSE expanding rings are manufactured by winding a flat wire with a constant cross-section, rather than by stamping.

Their manufacturing process offers the advantage of no stamping burrs or material loss. The fact that they have no ears makes installation easier, as there is no interference with adjacent components in the assembly.

They are highly reliable and are unlikely to dismantle on their own.

FS and FSE expanding rings are available with a disassembly method that depends on whether they are to be used internally or externally.

A wide range to suit all your requirements

The expanding ring range includes over 1000 standard sizes available in carbon steel and 302 stainless steel. However, if your application has special requirements, such as diameter, bending, material used, ring size, finish, ends, specific ring designs are possible, without tooling costs.

FSE expanding rings are available in inch sizes from 1/2″ to 11″.

FS expanding rings are metric, compatible with DIN 471 grooves and available in diameters from 13 to 300 mm.

A number of expanding rings are interchangeable with EATON rings.

Special parts can be offered from 4mm to 3000mm diameter and require no tooling costs.

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