M-thread Nut for Aerospace Parts

FXM series ball screw is square single nut type. Square nut itself has Housing function. Normally Ball Screws are used with small Axial play, but using oversized Balls allows for the application of light preloading and eliminates backlash (only Precision grade).

This allows for a more compact design compared to Flange type.

Our FXM series (Square single nut precision ball screw) of screw shaft screw material S55C (induction hardening), nut material  SCM415H (carburizing and hardening), the surface hardness of the ball screw part is HRC58 or higher.
