1)	Observe the permissible lateral force of the guide rail (see notes for mounting).
2)	For average load.
	Attention: Not to be used for the life expectancy calculation!
	For service life calculations use the load ratings and moments given in the tables for service life calculations.

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.

1)	Permissible range
2)	a = acceleration
3)	Fv/Cy = standard setting
