M-thread Nut for Aerospace Parts

KGG SXM series ball screw with smooth surface. low friction, low noise. they are widely used in linear motion system. Since the SXM series ball screw has a right-hand thread and a left-hand thread on one shaft, it has a bi-directional function.

Accuracy grade of SXM series (bidirectional precision ball screw) are based on C3 and C5(JIS B 1192-3). According to accuracy grade, Axial play 0 (Preload:C3) and 0.005mm or less(C5).

SXM series bidirectional 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.
