Secure gear boxes that can’t be attached directly to a machine or other surface. Transmit power, motion, and speed between machine components. Mount abrasive discs to the shafts of bench-top motors, grinders, and buffers. Attach to the shaft of your grinder or buffer to hold buffing wheels with a shank.

Choose from our selection of shaft adapters, bore reducers, and more. In stock and ready to ship.

Step Up shaft adapters attach to drive shafts and increase their diameter.This allows them to be adapted to larger components and connections without extensive modification or rebuilding. Step Down shaft adapters attach to drive shafts and decrease their diameter.This allows them to be adapted to smaller components and connections without extensive modification or rebuilding.

Rigid couplings and shaft adapters transmit power in applications without flexibility or misalignment. Rigid shaft couplings for round and keyed shafts firmly join two matching shafts together with set screws, one-piece slotted, or two-piece bodies.

Choose from our selection of threaded shaft adapters, including over 1,000 products in a wide range of styles and sizes. In stock and ready to ship.

Bore reducers, also called shaft adaptors or bore adaptors, provide a solution by allowing you to increase the diameter of your shaft. These clamp-style adaptors attach to the end of a shaft to enable the connection to an incompatible bore.

We offer a range of adapter kits from Engine to Gearbox kit as well as Gearbox to Transfer box kits. We cater to manual gearboxes as well as automatic.

Sun Gear Input Shaft Adapter For adapting the hydraulic motor shaft to the gear box, one required per gear box.

Choose the adaptor to suit your gearbox, and then choose the correct flexible shaft coupling for your engine / gearbox / application. Coupling adaptors for gearbox output couplings are designed to enable a standard R and D flexible shaft couplings to fit a non standard gearbox couplings.

Connect two shafts to transfer rotary motion from one to the other. Increase or reduce your shaft's diameter to fit equipment, or replace damaged shaft ends. Mill custom pulleys, threaded hubs, sprockets, collars, and sensor targets and mount them to shafts.
