Heavy-Duty Taper Lock Bushings for Mining & Quarrying Equipment
Mining and quarrying drives can combine shock, abrasive contamination and large shaft/hub sizes. Model selection should be based on the complete drive connection and actual duty; a large outside diameter alone is not enough.
Where the bushing enters the drive
Recommended series to review
| Application / duty | EP series to review | Selection note |
|---|---|---|
| Large Taper Lock | EP-5050 / EP-6050 / EP-7060 / EP-8065 | Review the published large-series dimensions and fasteners. |
| Extra-large Taper Lock | EP-10085 / EP-120100 | State inch/mm bore, shaft/keyway and lifting/service constraints. |
| QD heavy family | EP-J-STL / EP-M-STL / EP-N-STL | Use with the matching QD hub/sheave/sprocket. |
| Split Taper | EP-R / EP-S / EP-U / EP-W / EP-Y families | Confirm Type 1/Type 2 and the matching steel hub. |
Key selection criteria
| Selection variable | What to confirm |
|---|---|
| Torque/shock duty | Provide actual machine duty for connection review. |
| Shaft condition | Measure wear, fretting and keyway damage. |
| Contamination | Plan cleaning and inspection before assembly. |
| Service access | Allow for large fastener removal and safe handling. |
| Hub geometry | Confirm the mating taper/hub with a drawing where possible. |
Model suggestions are starting points for an enquiry, not a substitute for checking shaft diameter, keyway, mating hub geometry and the drive requirement.
