Slip Ring Selection Guides
Three ways to find the right part: start from the shaft you have, the machine you are building, or the contact technology the application needs. Each guide includes real specifications, current limits and the questions buyers ask most.
Find your slip ring by bore size
The shaft decides the bore. Start here if you already know the shaft diameter.
12.7 mm (1/2 inch)GK1233 (33 mm OD, 2-8 circuits) and GK1256 (56 mm OD, 6-36 circuits)View guide ›25.4 mm (1 inch)GK2586 — 86 mm OD, 6-36 circuits, 20 A per ringView guide ›38.1 mm (1.5 inch)GK3899 — 99 mm OD, room for cables and a pneumatic lineView guide ›50 mm (2 inch)GK50119 — 119 mm OD, large shafts and hose bundlesView guide ›
Find your slip ring by application
If you know the machine but not the part number, these pages start from the machine side.

Find your slip ring by contact technology
When the limiting factor is current, noise or wear, start from the contact system.
Not sure where to start? Send us four numbers — shaft diameter, circuit count, current per circuit and rotation speed — and we will come back with a model and a quote, usually within 5 hours. Minimum order is one piece, including custom configurations.
