Mounting The Payload - Festo ELFA-RF 70 Notice D'utilisation

ELFA-RF
Note
Danger of screws being pulled out, if the axis is only mounted to the covers and the
torque load around the longitudinal axis is too great.
• If there is high loading, mount the axis on the profile with additional mounting com­
ponents.
• Push the transverse connection over the complete stroke path from one end position to the other.
The guide axis will then position itself to the drive axis without any tension. If necessary, use a con­
nection with tolerance compensation.
• Tighten the M5 screws on the cover with 5.9 Nm. In the case of mounting accessories, comply with
the tightening torque specified in the associated product information.
5.1.2

Mounting the payload

• Position the payload in such a way, that the break-down torque
resulting from force F (parallel to the axis of motion) and lever
arm (a) remains as low as possible.
• Attach the payload to the slide with screws and centring
sleeves.
• Take the maximum screw-in depth D into consideration
(è Tab. 2).

Note
A warped attachment component bends the slide
and shortens the service life of the guide.
• Use an attachment component with an even sur­
face.
Evenness: t = 0.01 mm.
