3 .2 .1 Internal Anti-Rotation Option
IMA-SA33: In order to achieve linear motion with the IMA-S a form of external anti rotation must be
attached to the rod end. If the machine/application design does not allow for this, an internal anti-
rotation option is available on the 33 product size and is designated as with the code “SA”, IMA-SA33.
3 .2 .2 Screw Selection
BN05, BN10, BN20, RN04, RN05, RN10: Both roller screw and ball screw technologies are offered.
Contact Tolomatic for application review and assistance in selecting a screw technology.
