      FH and FHE expanding rings

      FH and FHE expansion rings, also known as Snap-Rings, are square-edged, single-turn rings with a gap.

      The special feature of FH and FHE expansion 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.

      Finally, Smalley’s FH and FHE expansion rings are designed for mounting in a bore.

      A high-quality manufacturing process

      FH and FHE expansion 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 disassemble themselves. They are available with a disassembly method that depends on internal or external use.

      A wide range to suit your requirements

      The range of expanding rings 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.

      FHE expansion rings are available in inch sizes from 1/2″ to 11″.

      FH expansion rings are in metric and are compatible with DIN 472 grooves.

      They are available in diameters from 13 to 300 mm.

      A number of expansion rings are interchangeable with EATON rings.

      Special parts can be offered in diameters ranging from 4mm to 3000mm 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.

      As always, don’t hesitate to contact our product expert for more information.
