(1) Required for lubrication of the linear ball bearing guide.

(2) For information about greater strokes, contact your local Schneider Electric representative.

(3) Depending on load and stroke.

(4) Maximum permissible forces and torques decrease at increasing velocities. Refer to the characteristic curves following this table.
