A universal joint is a solid coupling that allows two rotating shafts to be connected together. The bearing in the universal joints allow the transmission of torque and rotary motion of two shafts that are not aligned to each other. They have a maximum operational bending angle per bearing of 45 degrees and come in steel and stainless steel with protection bellows to stop the ingress of dirt in the bearings.
Whether you need universal joints to connect shafts across an angle discrepancy or clevis joints for connecting to rods, we can provide you with the technical assistance and data you need for your application. We have both metric and inch sizing products where available.
Our range of ant-stiction air cylinders complements our range of linkages by providing smooth and efficient operation of applications attached to the joint.

Bellows available for single universal joints. They allow full protection against ingress of dirt. Can be filled with grease for long term lubrication.
The joint capacity to transmit a regular torque at a constant load with no shocks, for a long period, mainly depends of the number of revolutions per minute and the inclination angle a° of the two axes. The diagram on the following pages are based on this. Each curve corresponds to the joint size (outside diameter "D") and represents the torque that the joint can transmit depending on speed and working angle a°.
The diagrams can be directly read if angle (a°) is 10°. For wider angles, torques are reduced, therefore these are to be corrected using the correction vales (F) relating to the angle shown in the table.
Important Note: Diagrams' values are merely indicative and refer to the single joints only. When choosing a double joint, you have to consider that they can transmit a torque about 10% lower than the same sized single joints. Each application has its own particular motion characteristics, such as: shock loads, motion reversals, connected masses, kind of starting presence of elastic joints, stops and starts, etc..., that have to be considered when choosing the joint.
|Working angle a°||Correction value F|
Power = 0,65 kW
RPM = 230
With working angle a°, F = 1, we get point P. Torque = 27Nm corresponding to joint size "D" = 25/26mm = Types R3688.016 and R3689.012
With working angle a 30°, F = 0,45 (kW 0,65: 0,45 = 1,44 kW) we get point P1 Torque = 60 Nm corresponding to joint size "D" = 32mm = Types R3688.020 and R3689.016
We are entering the next phase of our relocation to a larger factory in Chichester, West Sussex. The next few weeks will see products start to be moved from our current site in Cranleigh, Surrey to the new warehouse.
There are thousands of parts to be relocated and whilst we are doing our best to ensure a smooth transition, this may cause slight delays to some shipments.
We expect to be have all parts relocated and full production capability for our new 35,000ft² facility running by mid-March. Thank you for your understanding.Continue to Website
