Martin-Flex© Couplings

Martin-Flex couplings provide all the desirable features of an ideal flexible coupling, including Taper Bush fixing. The Martin-Flex coupling is a “torsionally elastic’ coupling offering versatility to designers and engineers with a choice of flange combinations to suit most applications.

The flanges are available in either F (face) or H (hub) Taper Bush fitting or bored to size. 

With the addition of a spacer flange the coupling can be used to accommodate standard distance between shaft ends and facilitate pump maintenance. Martin-flex couplings can accommodate simultaneous maximum misalignment in all planes without imposing undue loads on adjacent bearings and the excellent shock-absorbing properties of the flexible tyre reduce vibration and torsional oscillation. Martin-Flex tyres are available in natural rubber compounds for use in ambient temperatures between -50ºC and +50ºC. Chloroprene rubber compounds are available for use in adverse operating conditions (e.g. oil or grease contamination) and can be used in temperatures of -15ºC to +70ºC. The chloroprene component should also be used when fire-resistance and anti-static (F.R.A.S.) properties are required.
