EJL 090 Frame

The EJL is available in 3 backlash levels, as low as 1 arc-min, to satisfy a variety of applications. Output options include single and dual shaft, hollow bore with keyway, hollow bore with shrink disc and robotic ISO flange. EJL is available in ratios as high as 90:1 in a single stage and maximum acceleration torque as high as 6250Nm.

Hardened and ground worms and bronze alloy wheels deliver high torque, smooth operation, and superior shock load absorption. Oversized taper roller bearings accommodate high radial forces. A unique 3 bearing arrangement maintains proper worm bearing preload over all allowable temperature ranges.
