Choosing The Right Taper Bush For The Job
There’s a lot to consider when choosing the right DESCH product for your specific application.
Conditions
From environmental exposure to system constraints, the right solution must align with how your equipment runs.
Key factors to assess include:
- Shaft diameter
- Shaft tolerance
- Transmitted power and load
Use Cases
The key is not where they’re used, but how they perform in your application.
Typical applications include:
- V-belt pulleys
- Couplings
- Fans and fan wheels
- Other shaft-mounted drive components
Connection
The correct taper bush must match the shaft and the drive component to create a secure and reliable connection.
Our options include:
- Required bore diameter
- Bush size
- Feather-key requirements

Maintain For Longevity
While DESCH products are engineered for long-term performance, appropriate maintenance helps protect reliability, extend service life, and prevent avoidable downtime.
- Select the correct taper-bush size and bore for the shaft
- Install the taper bush according to DESCH’s supplied instructions
- Ensure the shaft and mating surfaces are clean and correctly positioned before installation
- Verify the connection after installation and following relevant maintenance work
