Sprockets with taper-lock bushes
Taper-lock clamping bushes enable the precise axially-centred fixing of hubs on shafts. When used with sprockets, they offer the advantage of faster fitting and better centring than shaft-to-hub connections with keyways.

Fast fitting, precise centring
Sprockets with taper-lock bushes ensure a frictional connection between shafts and hubs. The conical locking mechanism consists of a hub and a bush.Axial screws press the bush into the hub, wedging it against the shaft and locking it in place.
Where higher loads are concerned, we recommend the use of a keyway as an additional positive connection. This type of connection is easy to fit, but it is sensitive to any slight imbalances when in operation.
