Spiral Retaining Rings are designed for weight and space-saving applications. This form of retaining rings or circlip often used to fasten assemblies on shafts (EXTERNAL type) or inside housings and bores (INTERNAL type). They are ideal for use in pressure gauge, actuator valves, Gear assembly, lock, Pneumatic clutches, (belt) pulley, connector, hose fitting....etc.

Features

The unique coiled-on-edge design of Retaining rings have assembly advantages
No gap- full 360° surface contact.
No lug or ears to interfere with the assembly.
No stamped burr- exceptional strength and stability of an assembly.
Easier to install / removal, greater design flexibility.
All these can significantly reduce production costs.

Custom products are a specialty of TSMC (Tech Spring Manufacturing Corp.), as a full service precision manufacturing company, our experienced engineers have extensive knowledge of custom parts, they are always available to assist you to conduct a comprehensive functional analysis of development and gives a feasible solution through our own formula from the preliminary design phase to fabrication that meets your application needs.

There are four critical factors when considering a Spiral Retaining Rings design such as Bore/ shaft (ID/OD), Load, Working height at which the load is applied and Material desired, as well as the other input parameters that contain the wire thickness, wire radial wall, active number of turns, work height, load at work height ... The input data as shown on the left table. And calculation results with spring rate (stiffness), working load (±10%), outer diameter at solid height, Working curve and Life cycles prediction where found in the down table.

Whether you need a standard or custom Spiral Retaining Rings, please send us your application requirement, our experts will hand-select or commend the best solution for your specific needs.
