Rigidity
An increased rigidity can be achieved with higher pre-tensioning force by using eccentric setting.
Acceleration
High accelerations are permitted if slippage is avoided. For this, the pre-tensioning force FV by increasing the eccentric setting; see diagram.
Attention: The maximum permissible load is reduced by the increase of the pre-tensioning force.
