HUB ShaftCoupler DCNC-D40-L65-B08.00mm

These are very high quality servo backlash couplings. They can take up very high torque and have zero backlash. We use them for NEMA34 stepper motors and for all servo motors. These are clamp type couplings. It is possible to make combinations of different shaft sizes. So for example if your steppermotor has a shaft of 14mm and your ballscrew has a size of 8mm, order one hub of 14mm and one hub of 8mm. Of course for each 2 hubs you need one spider. When you add one HUB to the cart, the website automaticly advises the compatible counter hubs, and spiders. In this way its easy to make any combination of 2 HUBS + Spider, to make the shaft coupler the correct size for your application.

Component features:

• A complete coupler consists of 2 HUBS and 1 Spider, any combination of bores can be made. Add to cart the first bore, the website will then advise the correct Counter HUBS, and also the spiders. In this way you can assemble a complete coupling.
• Several size bores from stock, or a custom bore made on the CNC lathe
• Inside BORE diameter range 8-25mm H7 tolerance
• Custom sizes may be special ordered
• Compensate for axial, radial and angular misalignment
• Ease of maintenance due to changing insert only -- cost effective
• 40mm diameter length 65mm (total assembly)
• Can be disassembled to fit tight installations
• See PDF manual and STEP files for details
