Couplings, Collars, and Adapters

Grainger carries a diverse supply of couplings, collars and adapters, all of which enable devices to properly work together. For instance, a shaft coupling can both deliver and disconnect power to help separate machines, improve flexibility and reduce shocks and overloads. Universal joints can promote movement in rigid rods and enable rotary motion to be transmitted. Use a motion control coupler to help transfer torque between moving parts and effectively reduce backlash. When you're in need of couplings, collars and adapters, come to Grainger first.
