The importance of idler rollers (idler rolls) with low rotational inertia
Lightweight, high-stiffness carbon fiber rollers exhibit lower inertia to acceleration
and deceleration (rotational or translational), and can run at higher speeds.
Composite rollers reduce waste while increasing productivity and efficiency.
Carbon fiber idler rollers provide better performance than traditional steel or aluminum
rollers, particularly when wide web widths, heavy loads, and faster speeds are necessary.
Consider this example where a 164 inch steel roller with an 11.25 inch O.D. was replaced
with a carbon fiber roller with the same dimensions:

Dura-Stat: STANDARD COATING. Wear resistant, conductive polyurethane which works to prevent buildup of static charge on rollers. Suits most idler roll applications. Economical, resistant to most chemicals and abrasion, repairable, and replaceable. Black in color with an appealing satin finish. Surface Finish: 32 μin Ra (0.8 μm Ra).
Dura-Clear: Durable clear-coat polyester urethane. Non-conductive. Surface Finish: 32 μin Ra (0.8 μm Ra).
Dura-Clear Gloss: Polished clear polyurethane, non-conductive. Similar to Dura-Clear, but has a mirror finish surface that is friendly to sensitive web materials such as very thin films or very thin film/foil laminates. Surface Finish: 4 μin Ra (0.1 μm Ra).
915D: Nickel Chromium Thermal Spray with Release offers wear resistance, traction, and release all in one coating. This coating has successfully served in many applications with adhesive coated web materials. The silicone release agent in this coating prevents even aggressive adhesives from sticking. Surface Finish: 215 μin Ra (5.5 μm Ra); Hardness Rc 58; Color: Silver-Gray.
LC4: Chromium Oxide Plasma Spray offers a rock hard, ceramic surface that has extreme resistance to abrasion and chemical attack. This coating can be polished to approximately 10 μin Ra (0.3 μm Ra) when sensitive web materials are to be run. Standard Surface Finish: 80 μin Ra (2 μm Ra); Hardness Rc 72; Color: Dark Green-Black.
