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. 1) Permissible range 2) a = acceleration 3) Fv/Cy = standard setting Dimensions 1) Eccentric setting Lube nipples - Funnel-type lube nipple - Form B - thread M3 Connection possible on two sides.
