RENCOL® Tolerance Rings are precision spring fasteners that are press fitted between two mating components. RENCOL Tolerance Rings generate a retention force that fixes those components together, while also satisfying other functional requirements such as compensating for thermal expansion, fastens annular components, reduces noise and vibration, predictable and repeatable slip and avoids resonance frequencies. Tolerance Rings also aid as an overload protection mechanism. RENCOL® Tolerance Rings offer customers engineering expertise resulting in customized fastening solutions.
