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.
4) Please inform about different preload.
The preload is set to Fpr max by Steinmeyer and can be reduced to a minimum Fpr max of 20 N. The maximum permissable axial load of Fmax is around 65 - 80 % of the preload.
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: 1530/2,5.8.245.270
