The SKF flex coupling are designed to accommodate misalignment and shock loads and dampen vibration levels. It is easy to install, maintenance-free couplings are available with either a machined-to-size or tapered bore. These coupling are also available with a taper bushing and it consist of 2 flanges and 1 tyre. The flex tyres are available in natural rubber compounds for applications ranging from –50 to +50 °C. Chloroprene rubber compounds should be used in applications where exposure to greases and oils are likely. These compounds can accommodate temperatures ranging from –15 to +70 °C. The chloroprene tyres should be used where fire-resistance and anti-static (F.R.A.S.) properties are required.
