The SEW-EURODRIVE MC3PEHT08 is a specialized configuration of the MC (Multi-Compact) Series industrial gear units. While the MC2 series you previously looked at was a 2-stage unit, the MC3 indicates a 3-stage reduction, providing higher gear ratios and higher torque output for more demanding applications.
Model Breakdown: MC3PEHT08
Using the SEW-EURODRIVE industrial gear unit nomenclature, the code translates as follows:
- MC: Multi-Compact Series (Industrial Gear Unit).
- 3: 3-stage reduction (Helical).
- P: Parallel shaft helical gear unit.
- E: Extended Bearing Distance (EBD). This version is reinforced to handle significant radial and axial loads, making it ideal for agitators, mixers, or aerators where the gearbox shaft also acts as the main agitator bearing.
- H: Hollow shaft with shrink disc (this differs from the "S" solid shaft in your previous query).
- T: Torque arm included (typically used for shaft-mounted units to prevent the gear unit from rotating).
- 08: Housing Size 08. (Torque capacity roughly between 20 kNm and 45 kNm depending on the exact ratio).
Catalog & Technical Specifications
For Size 08 units, the technical performance generally falls within these ranges:
| Feature | Specification (Approx. for Size 08) |
| Nominal Torque ($M_{N2}$) | Up to 48 kNm (approx. 425,000 lb-in) |
| Gear Ratio ($i$) | Typically 7.1 to 112 (for 3-stage units) |
| Mounting Position | Universal (Horizontal, Vertical, or Upright) |
| Standard Features | Monoblock housing, splash lubrication |
| Optional Features | Drywell seal (leak protection), Fan cooling, Oil heater |
Maintenance & Procurement Tips
If you are sourcing this for a site in Malaysia:
- Verify the "Drywell" Option: Since this is an "E" (EBD) model, it is often used in vertical applications (like water treatment or chemical mixing). Ask your distributor if the Drywell seal is included; it’s a physical tube that prevents oil from leaking down the output shaft even if the seal fails.
- The Shrink Disc ("H"): Ensure your maintenance team has the correct torque wrench for the shrink disc. Unlike keyed shafts, the "H" design uses friction—over-tightening or under-tightening will lead to shaft slippage or fatigue.
- Local Support: Since this is a larger industrial unit (Size 08), SEW-EURODRIVE Malaysia (Iskandar Puteri) can provide onsite laser alignment and vibration analysis which is highly recommended for MC series installations to ensure the EBD bearings reach their full L10 life.
Do you need the specific dimensions (CAD drawings) or the weight of the Size 08 unit for structural planning?
