Spirolox brochure - .PDF file.

TFC’s Spirolox retaining rings have been used in Cambridge University Eco Racing’s (CUER) World Solar Challenge vehicle. The rings are being used in two locations on the car: the drive motor, where the rings secure the main motor bearings to the non-rotating axle; and the front suspension where they hold spherical bearings in place in the wishbone assembly.

CUER’s vehicle incorporates space-grade solar panels with sun-tracking capability and a light, highly aerodynamic outer shell.

Spirolox retaining rings are manufactured by coiling from flattened round wire and are said to have many advantages over conventional die-stamped circlips or retaining rings.

Key benefits of application

  • Alex Robinson, part of the 60-strong design and development team at CUER, said: ‘The compactness, weight and load-bearing aspects of TFC’s Spirolox rings made them an ideal choice for both applications.’
  • Robinson added: ‘The low profile of the rings, which have no lugs to interfere with mating components, allowed us to keep the dimensions to a minimum and assist in the critical aspect of weight loss.’
