Rencol Tolerance Rings

Rencol Tolerance Rings is a global business, supplying high volume international blue-chip OEMs with bespoke fastening solutions.

Tolerance Rings are radial spring fasteners that are press fitted between two mating components, generating a retention force that fixes those components together, whilst also satisfying other functional requirements such as Torque Drive, Overload Protection, NVH Performance and Differential Thermal Expansion.

We operate specialist forming plant that allows us to produce rings with the optimum characteristics to meet individual customer requirements. Our plant is unique to Rencol and is custom engineered to meet our own specialised needs.

We have the expertise and processes to produce rings in most types of spring metal materials, including for example, steel, stainless steel, copper beryllium, incanel and hastelloy.

Typically application types include...

	Slip Clutch: Fixing components, whilst allowing predictable and repeatable slip to occur. Applications include steering systems, powertrain systems and electric motors.
	NVH/ Resonance: Fastening components and tuning assembly to a void resonance frequencies and reduce noise and vibration. Applications include hard disk drives, steering systems and electric motors.
	Differential Thermal Expansion: Ensuring components and positively retained over a wide temperature range. Applications include electric motors, gears, pulleys and impellers.
