Shaft Couplings (179 products containing 3232 Items)


A shaft coupling is used to transmit power from a driving shaft to a driven shaft. The shafts are arranged so that one is an extension of the other, or at an angle to each other. Couplings transmit torques without play and can also compensate for radial and axial misalignment, even at high levels of rigidity.


It is possible to have a rigid connection or a flexible connection that is able to dampen the above mentioned misalignment and vibrations. Shaft couplings are almost maintenance-free and fulfil their task to a high degree of precision throughout the entire service life. They are therefore also often used in situations where the drive must be extremely precise.


Shaft couplings are available in different versions, for example as: tyre coupling, flexible claw coupling, (curved) tooth coupling, fixed coupling, disk clutch, elastic coupling, fluid coupling, pin coupling and cylindrical clamping elements. Which option is the correct one depends mainly on the power to be transmitted, the field of application and the working environment. Shaft couplings, which must be resistant to moisture, rust formation or other (aggressive) ambient conditions, are also available in stainless steel or with special surface treatment.


Thanks to the extensive range of products, a suitable solution is available for each particular application, because, in addition to transmitting torque, each type of shaft coupling has certain ancillary functions: torsional stiffness (important for positioning accuracy), rupture-proof (e.g. for lifting applications) or not rupture-proof, vibration-dampening (for internal combustion engines) and compensating alignment errors (parallelism errors or angle errors).


Sometimes the installation options also play a role (e.g. mounted axially or radially). If the situation requires it, shaft couplings can also be counterbalanced. If a distance must be bridged between the shafts, components known as spacer couplings can be used. The shaft offset is often referred to as DBSE (distance between shaft ends).


There are also shaft couplings that can be used at high ambient temperatures (e.g. couplings completely made from metal) or in potentially explosive areas where the components must meet the FRAS and/or ATEX guidelines.


Shaft couplings can be found in virtually every industry: (petro)chemicals, the food and drug industries, mechanical engineering, maritime applications, and by no means least in agriculture and forestry, as well as fisheries.


Various standards are relevant for shaft couplings, for example, DIN 740, DIN 115 and DIN 116.

Dear visitor,

How is ERIKS handling the recent developments regarding COVID-19?
The new coronavirus is currently expanding. ERIKS has taken all necessary precautions to protect its employees. The shipment of products ordered on our webshop proceeds as usual.

Which measures has ERIKS taken?

  • ERIKS employees practise the current hygiene instructions as set by the RIVM (including social distancing of 1.5m);
  • All employees essentially work from home, excepting our Logistics department;
  • Picking up your orders from ERIKS locations is no longer possible.

Impact on delivery
Currently the spread of COVID-19 is not affecting the delivery performance of ERIKS. Orders are both handled and shipped normally*. We keep in close contact with suppliers who have production sites in areas struck by COVID-19. When necessary, we will seek alternatives to guarantee our deliveries as well as possible. Generally speaking, our stock is sufficient. However, because the situation in the affected areas can change at any moment the status regarding our delivery remains a snapshot of the current situation.

** Exceptions to this are facemasks, overalls, disinfectants and related hygiene products. Unfortunately, due to a worldwide shortage these products are currently unavailable.
