All Insert and Jaw Type Couplings

0.06 to 44 Nm. Max Speed: 3000 RPM.

Max Speed: 3000 RPM. Parallel out of line compensation. Temp Range -20 oC to +60 oC. Oldham couplings are designed to transfer torque between two parallel, but not colinear, shafts. They have three discs, one coupled to the input, one coupled to the output, and a centre disc that is joined to the first two by tongue and grooves. This type of coupling is ideal for applications where it is difficult to move shafts to allow the coupling to be installed. The centre disk can be fitted after the hubs have been assembled and aligned.

All Insert and Jaw Type Couplings

Miniature aluminium curved jaw flexible couplings. 2 to 160 Nm. Match only hubs and spiders from listings SPIDER TYPE C. Inserts are held between the jaws of two hubs.

Discs (either red as standard with blue or white optional) are available to purchase separately. Flexible couplings transmit torque and rotational angle while absorbing misalignment. When the misalignment exceeds allowable values, vibration may result or the life of the coupling may become shortened. Zero backlash in low torque application, made capable by having the hubs pressed in a spacer. Can be used as a flexible coupling in a high torque application. Polyurethane spider.
