Taper Lock Bushings for Pump & Compressor Drive Applications

Pump and compressor drives place a premium on alignment. The bushing must match the sheave, pulley or coupling hub, and the complete rotating assembly should be checked after service rather than treating the bushing as an isolated part.
Where the bushing enters the drive
Recommended series to review
| Application / duty | EP series to review | Selection note |
|---|---|---|
| General pump/sheave | EP-2012 / EP-2517 / EP-3030 / EP-4040 | Select from the actual shaft and sheave/hub. |
| Higher-duty belt drive | EP-3030 / EP-3535 / EP-4040 / EP-5050 | Provide power/speed, shock duty and hub details. |
| Large XT hub | EP-XTB50 through EP-XTB120 | Use only when the mating XT hub geometry matches. |
Key selection criteria
| Selection variable | What to confirm |
|---|---|
| Shaft diameter/keyway | Measure both pump/compressor and driver sides if a complete drive is being changed. |
| Alignment | Record the installed axial position and alignment method. |
| Duty | Provide power, speed and starts/cycle information. |
| Mating hub | Identify sheave, pulley or coupling interface. |
| Environment | State corrosion, temperature or contamination concerns. |
Model suggestions are starting points for an enquiry, not a substitute for checking shaft diameter, keyway, mating hub geometry and the drive requirement.
