Newton metre is a compound unit of torque corresponding to the torque from a force of one newton applied over a distance arm of one metre.
1 Nm = 0.738 foot-pounds
SPEED DEMON Guide 's precision isn't affected by the system length. Since the movement of bearing is less 3, the running precision guarantees according to rail length without accumulation.
