Used to make a shaft larger or smaller, rigid shaft adapters are fully machineable so users can alter their configuration and size. Eliminating the need for welding or full shaft replacement, they’re available with keyways for additional torque and fixed shaft phasing or without keyways for non-keyed shafts.

Shaft Adapters

Step-Down Shaft Adapters

Our step-down adapters are useful for making connections with smaller shafts. They utilize clamp-style coupling ends to prevent shaft marring. Available for use as is with no welding required, these shaft adapters are fully machinable, allowing for configuration and size alterations to suit your needs.

Step-Down Shaft Adapters With Keyways

These keyed shaft adapters also serve to make shafts smaller. Featuring keyways, they offer additional torque capacity over standard step-down adapters as well as fixed shaft phasing. Welding is again unnecessary for these products, and they’re completely machinable for configuration and size modifications.

Step-Up Shaft Adapters

This variety of shaft adapter is used to enlarge a shaft. Like our step-down adapter types, step-up shaft adapters come ready to use as is without needing any welding, and they’re machinable based on your configuration and sizing needs. Their clamp-type coupling end will better protect your shaft from marring.

Machinable Shaft Adapter Max

This versatile shaft adapter type is thoroughly machinable, giving you the option to step down, step up, or extend a shaft. You can also choose to alter its configuration, with square, hex, and threaded modifications available. The machinable Shaft Adapter Max allows for pulleys, drive slots, press-fits, and other specialty components.

Machinable Shaft Adapter Max With Keyways

As with standard varieties, the Shaft Adapter Max with Keyways allows you to step down, step up, or extend a shaft as it’s completely machinable. It’s also modifiable for a square, hex, or threaded shaft configuration, with specialty components like pulleys, drive slots, and press-fits. However, the Shaft Adapter Max with Keyways increases torsional holding power and enables fixed shaft phasing for vibration reduction.

Threaded Shaft Adapters With Keyways

This adapter type will join a threaded bore with a smooth and keyed shaft. Like standard threaded shaft adapters, these adapters with keyways feature a clamp-type coupling end for shaft marring prevention. They don’t necessitate welding for enhanced ease of use, and they allow for sizing and configuration changes as fully machinable components.

Application of Shaft Adapters

The primary function that shaft adapters serve is to create effective and reliable connections. For example, a shaft adapter is applicable when one shaft, or both, isn’t of sufficient length to utilize a coupling for creating a connection. Similarly, if the shafts have dissimilar diameters, you can use a shaft adapter to make up the sizing difference between them.

Shaft adapters can also save you from having to replace a shaft if doing so wouldn’t fit your budget or isn’t advisable for any reason. These products can even prevent the damage a shaft would otherwise incur from poor power transfer and motion. Versatile adapters are well-suited to connection applications in the healthcare, food and beverage, manufacturing, material handling, and packaging industries.
