Sleeves
Manufactured in Ahmedabad by Gopal Engineering Works, these slip-on sleeves — air expander, friction/differential, adapter, FRP and rubber-coated types — fit over standard air shafts and dead shafts to grip cores concentrically and transmit torque without slippage. Designed for consistent tension and true running across slitting, winding and converting lines, each sleeve is built to drawing or matched to your existing shaft and core dimensions, serving printing, packaging, paper, film and foil converters across India.

Frequently asked questions
- What does an air expander sleeve do?
- An air expander sleeve slips over an air shaft or dead shaft and, when the shaft is inflated, grips the core concentrically so the roll runs with even tension and minimal run-out during slitting or winding.
- What is the difference between a friction sleeve and an adapter sleeve?
- A friction (differential) sleeve uses controlled slip to allow individual rewind lanes to run at slightly different tensions, while an adapter sleeve is a plain concentric spacer used to mount a larger-bore core on a smaller-diameter shaft.
- What core sizes and shaft diameters are available?
- Gopal Engineering Works manufactures sleeves — including air expander, friction/differential, adapter, FRP, and rubber-coated types — to suit standard core IDs and shaft diameters; share your core bore and shaft size for a matched set.
- What materials are sleeves made from?
- Sleeves are available in FRP (fibre-reinforced plastic) for a lightweight, high-strength option, as well as rubber-coated variants for applications that require a grippy or protective outer surface.
