Centa Flex CF DS 25 SAE 11.5 26 spline Dual Stage Coupling. These couplings a designed to cope with uneven flywheel rotation at low revs, a common problem with marine diesel engines. It works by using two stage damping effect, stage 1 is a torsionally very soft roller coupling this takes care of low speed damping. Stage 2 is a stiffer tough jaw coupling which is engaged as load increases enabling both stages to act together in parallel. One of the main aims is to reduce gearbox chatter (a metalic clattering noise that can lead people to believe they have a transmission problem) This type of coupling also provides very smooth asscent of the second stage which is still soft enough even at high loads to provide good torsional damping under all conditions.
Available to suit a wide range of SAE type flywheels and most marine gearbox packages. We have a wide range of Centa Flex Couplings available from stock. Please phone for details. Prices do not include carriage and VAT.
