Your experts for backstops, freewheel clutches, couplings & more

The strong team of a+swelcomes you to our homepage!

 

In 1978 a+s antriebstechnik+spannsysteme vertriebsgesellschaft mbh was founded in Hamburg as a service centre for Stieber clutches. Since then our organization has developed to a specialist in power transmission products. For over 30 years we have been very successful in the market and represent many products of wellknown, mostly German manufacturers in the north of Germany.

From a+s you can expect the highest quality standards in every single field!

In our wide range of goods you will find classic backstops with torque arm (RS/BW), ball-bearing clutches (CSK) as well as couplings of all types, e.g. ROTEX® (torsionally flexible), ROTEX GS® (backlash-free), BoWex® curved-tooth gear couplings, RADEX® steel-lamina couplings, metal-bellow and safety couplings. Those looking for shaft-hub-connections like locking assemblies, locking elements or shrink discs, will also find them at a+s.

We offer the perfect solution for your power transmission applications, exactly what you need!

Every item provides special characteristics. Tosionally flexible couplings, the ROTEX® for example, have precisely manufactured dimensions and low weights with high transmission torques. They are used often to drive pumps or fans. Beyond our primary core competence (roller clutches and sprag clutches used as backstops, indexing clutches or overrunning clutches) we have continuously broadened our range and are able to offer a whole palette of power transmission products. a+s provides professional technical advice on freewheel clutches, couplings or locking assemblies and offer short delivery times. V-belts, roller chains, non-contact seals and Taper-Lock products round out our range.

 

We are confident that we will be able to convince you of our exceptional commitment to quality, service and flexibility - that we provide to all our customers!
