Parameter
| Base Model | 12PK (pitch=3.56mm) |
| Length | 1295mm (Pitch Circumference) |
| Coating | +3mm (Common)It can also be customized. |
| Material | CR/EPDM Base+abrasion-resistant 85A PU/Super-soft 35A Polyurethane/rubber coating |
| Grooving | Transverse (Crosswise) Slots |
| Processing | CNC Precision Milling |
| Hardness | Base layer 90A / Cover layer 50-85A (customized according to the grasping requirements) |
Primary Applications
Medium-sized plastic pipe extrusion: e.g. haul-off for PE, PVC and PP pipes.
Cable production: in particular, haul-off of cable sheaths following continuous water-cooling.
Rubber profile processing: conveying sections requiring constant tension and non-marking gripping.
What are the differences among these three coverings?
| Feature | 85A Abrasion-Resistant PU | 35A Super-Soft PU | Industrial Rubber Coating |
| Hardness (Shore A) | 85A (Firm/Hard) | 35A (Very Soft/Gummy) | 55A – 70A (Medium) |
| Primary Advantage | Extreme durability and wear resistance. | Superior grip and non-marking contact. | Excellent shock absorption and heat resistance. |
| Grip / Friction | Moderate; smooth surface. | Maximum; high-tack surface. | High; consistent traction. |
| Wear Resistance | Excellent; resists cutting and heavy friction. | Low; susceptible to wear over time. | Good; balances durability with grip. |
| Product Protection | Best for heavy, rough, or sharp products. | Best for delicate wires, glass, or thin-walled pipes. | Versatile; good for standard industrial parts. |
| Chemical Resistance | High resistance to oils and chemicals. | Moderate resistance. | Varies (EPDM for heat, CR for oil). |
| Typical Application | Heavy-duty conveying, tile industry, abrasive parts. | Wire stripping machines, delicate cable haul-offs. | General pipe extrusion, packaging, labeling. |
yonghang Professional Selection Tip:
Choose Rubber if your priority is Versatility and handling higher temperatures.
Choose 85A if your priority is Belt Life.
Choose 35A if your priority is Precision Feeding of delicate materials.
FAQ
