Spindle axes ELGC-BS-KF, with recirculating ball bearing guide Data sheet Characteristic load values The indicated forces and torques refer to the centre of the guide. The point of application of force is the point where the centre of the guide and the longitudinal centre of the slide intersect. These values must not be exceeded during dynamic operation. Special attention must be paid to the deceleration phase. Distance from the slide surface Max. permissible forces and torques on the slide (strength limits) Size 32 Fymax. Fzmax. Mxmax. Mymax. Mzmax.

Spindle axes ELGC-BS-KF, with recirculating ball bearing guide Data sheet Calculating the service life The service life of the guide depends on the load. To be able to make a statement as to the service life of the guide, the graph below plots the load comparison factor fv against the service life. These values are only theoretical. You must consult your local Festo contact for a load comparison factor fv greater than 1. Load comparison factor fv as a function of service life l Example: A user wants to move an x kg load. Using the formula (a page 10) gives a value of 1.5 for the load comparison...

Spindle axes ELGC-BS-KF, with recirculating ball bearing guide Data sheet Feed force F as a function of service life l Recommended deflection limits Adherence to the following deflection limits is recommended so as not to impair the functionality of the axes. Greater deformation can result in increased friction, greater wear and reduced service life.
