| Specification | Description |
|---|---|
| Product Name | Hydrocone Dust Seal Collar (similar to Part No. 873.0892‑00) by Novincsm (compatible with Delta/Sandvik models) |
| Material & Composition | Nitrile Rubber (NBR, 70–90 Shore A) or Polyurethane (PU) with metal backing ring; dust- and oil-resistant; carbon black filled |
| Hardness | 70–90 Shore A (standard NBR); PU: 80–90 for enhanced durability |
| Operating Temperature | NBR: 30–120+ °C; PU: up to 150+ °C; continuous: 20–100+ °C |
| Dimensions | Inner diameter: 300–500 mm (for 36‑inch shaft); Outer diameter: 320–520 mm; Thickness: 5–15 mm; U/V cross-section: 3–10 mm |
| Approx. Weight | 0.3–1.5 kg per collar (depending on size; NBR density: 1.2 g/cm³) |
| Tensile Strength | 8–12 MPa (NBR); Elongation at break: 300–400% |
| Permanent Compression | <30% at 70 °C (22 h); ensures long-term sealing integrity |
| Color & Finish | Black (standard NBR); smooth surface with metal ring; optional green for PU |
| Application Method | Press-fit installation on hydrocone shaft; lubricate with silicone grease for easy assembly |
| Surface & Tolerance | Surface roughness: Ra 1.6–3.2 μm; Tolerance: ±0.1 mm (inner/outer diameter); Rated pressure: up to 5 bar |
| Wear Resistance | High (NBR: Taber wear <200 mg); excellent for dust sealing in mining applications |
| Thermal Resistance | Excellent up to 120 °C (NBR); optional UL 94 V‑0 flame resistance for PU |
| Manufacturing Process | Compression/injection molding; dust- and oil-resistant compound; custom sizes available |

Primary Function:
Seals the hydrocone shaft to prevent dust and debris from entering the bushings or oil system, maintaining optimal system performance.
Industries:
Mining in Kenya (granite crushing)
Cement plants (Nairobi / Mombasa)
Construction (sand production)
Types:
Rubber Collar (NBR): Dust sealing
Metal-Rubber Collar (PU): Enhanced durability
Complete Seal: Leakage-free up to 5 bar, extends shaft and bushing life by 20–30% by reducing dust ingress.
Cost-Effective: Approx. 150,000 IRR vs. OEM >300,000 IRR.
Market Compatibility: Fits Novincsm, Delta, and Sandvik hydrocone models in Kenya.
Easy Installation: Press-fit in 5–10 minutes; maintains low permanent compression for long-term operation.
NBR material limited to 120 °C (for hot Kenyan mines, PU is recommended).
Sensitive to chemical oils; avoid petroleum-based lubricants.
Custom sizes may require 2–4 weeks for import from Iran to Mombasa.
Installation:
Clean the shaft and lubricate with silicone grease.
Press-fit installation without twisting; follow torque specifications in the manual.
Maintenance:
Inspect for cracks or wear every 3 months.
Replace if permanent compression exceeds 30%.
Store in a cool, dry environment (5–30 °C).
Transport:
Packaged in dust-proof bags; available through Nairobi importers such as East African Machinery.
