Industrial HNBR Rubber Ball
Product Characteristics
| Material | CR Rubber |
| Diameter Range | 1 mm – 100 mm (custom sizes accepted) |
| Tolerance | ±0.05 mm (standard), tighter upon request |
| Chemical Resistance | Withstands hydrocarbon oils, fuels, greases, hydraulic fluids, and many industrial chemicals - broader compatibility than NBR in elevated-temperature conditions |
| Heat & Oil Synergy | Hydrogenated nitrile formulation retains NBR-level oil and fuel resistance while extending continuous service temperature to 165°C - outperforming standard NBR in hot, oily environments |
| High Mechanical Strength | Tensile strength up to 30 MPa with excellent tear and abrasion resistance, suited for load-bearing and high-wear sealing roles |
| Weather & Ozone Durability | Saturated polymer backbone eliminates ozone cracking - survives long-term outdoor and under-hood exposure without hardening or surface degradation |
| Dynamic Fatigue Endurance | Outstanding flex-life and resistance to repeated compression cycling, ideal for valves, pumps, and belt-driven equipment under continuous operation |
| Lead Time | 1-3 weeks |
| Payment Term | L/C, T/T, WEST UNION, PAYPAL, ESCROW |
| Hardness | 20-90 Shore |
| Quality certification | ISO 90001:2008, TS16949, FDA, REACH, ROHS, SGS |
Key Features
The Industrial HNBR Rubber Ball is engineered for severe-service applications where standard NBR reaches its thermal and durability limits:
- Heat-Resistant Oil Sealing - Hydrogenation raises the upper continuous service temperature to 165°C while keeping the excellent oil and fuel resistance that nitrile is known for - a combination no other general-purpose elastomer matches at this cost point.
- Heavy-Duty Mechanical Performance - High tensile strength (up to 30 MPa) and superior abrasion resistance allow these balls to serve as load-bearing seals in high-pressure valves and aggressive pump environments.
- Ozone-Immune Durability - The saturated polymer chain resists ozone and UV attack, eliminating the surface cracking that shortens NBR service life in outdoor or under-hood locations.
- Long Dynamic Life - Exceptional flex-fatigue resistance ensures reliable performance through millions of open-close cycles in check valves, solenoid valves, and reciprocating pumps.
- Refrigerant-System Ready - Fully compatible with modern HFC refrigerants and POE/PAG lubricants, making it the standard for automotive AC compressors and industrial chillers.
- Precision OEM Tuning - Acrylonitrile content, hardness, and low-temperature modifiers are adjustable to balance oil resistance, cold flexibility, and cost for each specific application.
Common Applications
- Automotive Powertrain - Sealing balls in timing belt tensioners, oil pumps, EGR valves, and transmission control bodies exposed to hot oil and vibration.
- Automotive Air Conditioning - Compressor valve balls and check-valve spheres in HFC refrigerant systems.
- Oil & Gas Downhole - Sealing balls in drill tools, wellhead valves, and artificial-lift equipment facing high pressure, high temperature, and sour crude.
- Industrial Hydraulics - Check-valve and pump balls in high-pressure hydraulic systems operating above 120°C.
- Refrigeration & HVAC - Sealing spheres in commercial compressors, chillers, and heat pumps.
- Power Transmission & Heavy Machinery - Cushioning and sealing balls in belt drives, construction equipment, and mining machinery.
Quality Assurance
- Every lot undergoes dimensional inspection, hardness testing, tensile verification, and compression-set analysis before release.
- Full batch traceability and compliance documentation (RoHS, REACH, automotive-grade certificates) available upon request.
- OEM/ODM support with custom compounding, private labeling, and dedicated production scheduling.
