hand thread and non-standard leads upon request..
2) Additional ball circuits for extended load capacities are
also available.

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: 1234/1.12.355.397 T7 P
