Step-Down Shaft Adapters
Our black-oxide steel shaft adapters are designed to reduce the diameter of your shaft while adding length, providing you with the flexibility you need for your industrial applications. Featuring a two-piece coupling that clamps onto your existing shaft and a smaller shaft that extends from the other side, these adapters offer a firm and even grip that won't damage your shafts. They are easy to install, and you can tighten the clamping screws to ensure a secure connection. These adapters are ideal for use in dry environments and are made of strong materials to ensure long-lasting performance.
