HTD 8M Taper-Lock timing pulleys

8M Taper-Lock timing pulleys are mounted on the shaft with a taper bush, purchased separately. The seat size increases with the size of the pulley and is given in the product name.

HTD 8M Taper-Lock timing belt pulleys - no lathe, press or puller

You fit the pulley onto the shaft together with the bush and clamp it with screws - without a lathe, press or puller. On production lines this means shorter downtime when replacing a pulley or changing the ratio. The bush does not damage the shaft, so the pulley can be removed many times. Smaller pulleys are made of C45 steel, and larger ones of grey cast iron. Taper-Lock bushes are standardised and readily available in many bore diameters.

Frequently asked questions about a shared bush for HTD 8M synchronous pulleys

Can I use one bush in different pulleys?

Yes, if the pulleys have the same seat. This is convenient when changing the ratio - the bush is moved to the new pulley.
