Composite
Cores & Rollers

For light weight, high speed.

 

Composites ... the Better Choice

Up to 75% lighter than metals Lighter rollers mean less inertia and higher speeds.

High stiffness-to-weight ratio Reduced machine wear.

Increased Machine Life Less wear and tear on bushing, bearings and journals.
