(8 arms with 45 degree center angles)
Aluminum rollers are designed to provide low rotational inertia, with little deflection. This performance is accomplished with a unique aluminum extrusion that yields an excellent strength to weight ratio.
Live shaft models (with fixed journals) or dead shaft models (roller rotates with bearings on a fixed inner shaft) are both standard options.
Standard diameters for aluminum rollers range from 60 mm up to 200 mm, with lengths that can exceed 7000 mm. Rollers can be dynamically balanced and mechanically straightened to customer specifications, and they can be finished with various surface treatments and coatings. We offer a standard set of sizes, but custom manufacturing is possible.
V belt and flat belt engagements are available.
Lightweight, low-inertia idler rollers.
Bowed rollers are used to spread the web material uniformly in order to eliminate creases or wrinkles.
Air shafts are available in steel, aluminum, or lightweight carbon fiber; suitable for all types of winding applications.
Lightweight air bladder chucks mount on a core shaft to grip cores with various diameters. Connecting air hose allows two chucks to inflate simultaneously.
Double E safety chucks make shaft loading simple. Flange or foot-mounted models available with turned square, square, circular, or triangular shaft engagements.
