SPEED DEMON FAMILY

The SPEED DEMON Family consists
of 3 linear bearing configurations:
SG, OSG & EL 300.

These systems employ round shafting,
aluminum bodies and dual, angular contact -
sealed for life - roller bearing wheels. Each
has built-in preload adjustability. SPEED
DEMONS are capable of speeds up to 10
meters per second. SPEED DEMONS are
easy to install, lightweight and inexpensive.

NOTE: Concerning Mx, My and Mz Moment Loads
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 doesn't have effect on the system length. Since the movement of bearing is less ±3§­, the running precision guarantees according to rail length without accumulation.
