Inner Frictional Connections IS

True concentric running can even be improved by pre-centring the hub. The IS4.1 units are especially designed for conveyor drums and their particular load conditions.

Internal Locking Units Type IS are available in the following forms:

• Type IS1 for small installation space
• Type ISN 1 axial located
• Type IS4 for high torque transmission
