| B | SPA | General industrial |
| C | SPB | Higher power |
| D | SPC | Heavy duty drives |
How to choose the right section
- 1Check the pulley groove profile and width.
- 2Match the belt section to the pulley standard.
- 3Confirm belt length reference before ordering.
- 4Verify operating speed and torque to avoid undersizing.
FAQ
- Q: Can I replace A with SPZ? A: Not directly. Use the matching profile for the pulley.
- Q: Are wedge belts stronger? A: They transmit more power for the same width.
- Q: Do you need pulley details? A: Yes, groove profile ensures correct fit.
Use belt markings or pulley measurements to confirm the correct section. If the pulley is worn, share a photo of the groove for verification.
