FAQ :
1. What standards do these pulley sleeves comply with?
- Full compliance with:
- DIN 5480/5482 (Involute splines)
- ISO 4156 (Straight-sided splines)
- DIN 6885 (Taper lock system)
- Material certifications: EN 10083-3 (42CrMo4 alloy steel)
2. How does CNC broaching improve performance vs traditional milling?
| Factor | CNC Broaching | Conventional Milling |
|---|---|---|
| Keyway Accuracy | H7 tolerance | H9 tolerance |
| Surface Finish | Ra 0.8μm | Ra 3.2μm |
| Production Speed | 5-8 pcs/hour | 2-3 pcs/hour |
| Tooling Cost | Higher initial cost | Lower cost |
3. What's the lead time for custom sizes?
- Standard sizes (Ø12-80mm): 15 working days
- Large sizes (Ø80-300mm): 25 working days (includes forging time)
- Expedited service: +30% fee for 50% faster delivery
4. How do I confirm the correct sleeve for my pulley?
Provide these 3 measurements:
- Shaft diameter (with tolerance)
- Keyway dimensions (width/depth)
- Pulley taper angle (typically 1:12)
(We'll send CAD confirmation within 24h)
5. What maintenance is required?
- Zero maintenance design:
- Pre-lubricated during assembly
- Hardened surfaces resist wear
- Inspection interval: Check torque values annually (recommended 120-150Nm for M12 bolts)
