Aluminium - Flexible.
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.

High capacity, square gib slides are ideal for precision machine tool applications.
The square gib design offers high load capacity and accuracy and withstands force in any direction. Gib is adjustable. Straight line accuracy 0.00254mm. Base is fabricated from A2 tool steel and hardened to Rc58-62. Saddle or riding portion of the slide is fabricated from low carbon steel and can be drilled, tapped and milled for mounting purposes. All slides feature Rulon bearing material for low friction. Stick-slip is virtually non existent as friction at startup and low speeds is virtually eliminated. No lubrication required. Rulon is practically inert to acids, bases and solvents making these slides a good choice for contaminated environments. Temp range minus 240 oC to +300 Deg C.
