As long-time suppliers to the UK manufacturing industry, Challenge Europe is aware that every application is different – many production needs can be met from its extensive range of standard types but often a custom variant is required.
Kevin Moorcroft, Managing Director explained: “We carry a full range of flat, shakeproof, mudguard, copper grip and terminal cup washers, as well as crinkle, sealing, Belleville, cup, spring washers and “O” rings. All of these can be produced to custom specification to suit the needs of UK assemblers. Where vibration and sealing are specific problems then we also offer the Dubo retaining ring and toothed collar ring systems.”
The Dubo ring system is often used in preventing leakages from transformer oil reservoirs ranging to more demanding roles within the power generating industry and elsewhere such as machine tools and hydraulic systems.
Complementing the retaining ring is the Dubo toothed collar ring which is intended for use in combination with high quality steel nuts (8.8), making it possible to admit any desired bolt tension. The deformation of the Dubo ring causes the locking and tightening effect according to the dubo principle.
