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:
