Mechanical power transmission couplings

Mechanical power transmission couplings are flexible coupling units created to transfer mechanical power from one source to another. Traditionally these are couplings such as universal joints, jaw couplings, elastomeric couplings and other couplings like spring or grid couplings.
Traditionally these couplings require maintenance and replacement of internal components due to the design limitations of the technology
Universal Joints require constant greasing and the internal bearing cross be replaced due to wear, jaw couplings or elastomeric couplings are only able to flex 1/2 to 1 degree, anything beyond that means the edges of the elastomeric insert or “spider” wear and need replacing, the pressure connection of a standard elastomeric coupling also means by being compressed over time this compression means the spider stops absorbing as much of the vibration generated by the coupling being used and its degree of angular alignment. This means the spider insert will need to be replaced.

Grid couplings are they the right choice for you?

Grid coupling or Biddy Coupling replacement

Grid couplings or Biddy Couplings are flexible couplings used in high torque low misalignment applications. Biddy couplings were originally invented by Dr James Biddy in 1917, by mating two shafts together with hubs and a specially wound and tempered spring to allow the two shafts to become angularly misaligned. Grid couplings small amount of angular […]

New single direction Coupling now available, great for motors, pumps and conveyors application

Universal joint alternative -Twin Spring Coupling products alternatives to all other flexible shaft couplings

Single direction coupling by Twin Spring Coupling to add to our range of couplings. Traditionally the couplings with its 2 springs, had one counter wound, so allowing the couplings to be multi directional. We have had a number of customers in the industrial sector especially ask for a single direction coupler, especially as they didnt […]
