1) Left
hand thread and non-standard leads upon request.
2) Additional ball circuits for extended load capacities are
also available.
3) Dynamic load capacity Ca: Permissable dynamic
axial load resulting in 1 x 106 rev. service life.
The specified adjustment lengths take into account a certain overrun and can also be exceeded if required.
When ordering, information on the installation direction of the nut, deviating preloads, required tolerance classes and an appendix "P" for backlash-free execution should be supplied. Example: 1112/0,5.8.145.170 T3 P
If there is no other detailed information, the ballscrews are delivered grease lubricated with Klueber Staburags NBU 8 EP.
