Replaces Universal joints, Beam coupling, Jaw coupling and spring couplings

Universal Joints  – U joints have 4 internal bearings or a block and pin design while flexible the pivot (block or bearing cross) needs lubrication otherwise the friction created due to use will cause bearing failure. The 3 piece design 2 yokes and bearing cross is replaced by our 1 piece integrated design, means less that can go wrong. With our coupling there are no internal bearings, so lubrication/maintenance becomes a scheduled semi annual event.

Jaw Coupling – Jaw type coupling either standard jaw couplings or curved jaw couplings, is a elastomeric coupling also called a Spider Jaw Coupling that again being a 3 piece design, two hubs and a insert or “spider”. Its job is to run at high speed but low angle of misalignment, anything outside of the 2° it starts to wear out the spider. The spiders job is also to absorb vibration. Our coupling with its twin torsion at low angles of misalignment it can run at the same high speeds, with higher torque and the same twin springs absorb vibration without the need for a insert.

Beam Coupling – Beam couplings are available in single beam or multi beam, the design is a simple one, a metal cylinder with cuts in the side of it, this allows a degree of flexibility all be it small, typically its less than 2° for the multi beam, 1° for single beam. These servo type coupling also have a low torque capacity. Our twin spring offers the same torsional rigidity but with increased flexibility. Like the our coupling it is also a one piece design.

Bellows Coupling – It also is a three piece design, two hubs and the bellows insert. It also has the same low angle of usage like that of the beam coupling, it runs at high speed but is only capable of low amounts of torque. We do the same but with increased torque.

Spring Coupling – The spring coupling has a design similar to the beam coupling. A one piece design with a spring and two hubs. It has a low torque capacity but can run at high speeds and can only work in a single direction and has a misalignment angle of 4°. Lovejoy Uniflex coupling is a good example of a spring coupling.
