The couplings consist of two hubs and a laminated stainless steel disc pack secured by a series of fitted bolts retained by nylon insert lock nuts. The couplings minimise the need for maintenance because they offer some allowance for misalignment and do not require lubrication. Single disc couplings accommodate angular offset, while double disc pack units with a spacer will allow for angular, parallel or combined offset. The disc pack, or spacer may be removed and re-installed radially, meaning the prime mover and driven machine need not be moved at all.
With hub pilot bores to simplify boring to requirements SKF Disc Couplings bring cost-effective high performance to applications and industries including petro-chemical (direct drive fan drives, pumps and compressors), printing and paper (positioning), plastics, power generation (high speed turbine type drives, alternators, pumps), refrigeration (compressors) and marine.
