Couplings Insert and Jaw
0.06 to 44 Nm. Max Speed: 3000 RPM.
Disk inserts. 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.

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.

Bearings and Spare Parts
Where alternative parts are offered, we make no claims as to their suitability. Selection of the most suitable bearings and parts is the responsibility of the customer. We recommend you replace bearings with the same type if that type is working well. High speed caged bearings are better suited to handle vibration than standard caged bearings.
