The company warns the repair industry to beware of unspecified driveshaft couplings

Flexible Couplings are considered an extremely sensitive and key component in a vehicle’s drivetrain.
SGF explains that original couplings are vehicle specific and are tuned and balanced to reduce or eliminate the vibration and disturbing harmonic frequencies and torque peaks generated.
They must be durable and withstand the maximum torque generated by the engine.
SGF says the repair industry should beware of copy couplings that can cause vibration and noise issues and early failure.
It states that generally, “many other low-quality couplings in the market are poor attempts to replicate the genuine performance of SGF Couplings.”
SGF explains that its Couplings are Original Equipment and supplied to many OEMs around the world. Each coupling is specifically engineered and NVH tuned for a particular vehicle model.
SGF is a German company specialising in torque transmission and anti-vibration solutions.
Unlike many copy couplings available in the market, SGF says it utilises its trademark Tenpu fibre technology: a combination of cord inlays vulcanised within select rubber compounds that operate in tension rather than pressure or shear load.
It says the Tempo fibre reinforcement fibres transmit the majority of the torque whilst the design enables the tuning of the coupling for the specific reduction of each vehicle’s NVH characteristics, resulting in optimal damping and the elimination or reduction of noise and vibration, improved tolerance to shock loads and compensation of radial, axial and angular misalignments. Further, SGF states its couplings also have a high-power density ratio.
SGF states that its genuine Couplings are available from all good distributors.
