Key Features
The NBR Rubber Ball for Industrial Sealing delivers reliable performance across a broad range of demanding applications:
- Superior Oil & Fuel Resistance - NBR's acrylonitrile content provides inherent resistance to petroleum-based oils, greases, gasoline, and diesel fuels, making it the material of choice for automotive and hydraulic systems.
- Wide Operating Temperature Range - Maintains flexibility and sealing integrity from −30°C up to +120°C, suitable for both cold-start and high-heat environments.
- High Resilience & Low Compression Set - Returns to original shape after repeated compression; minimal permanent deformation ensures long-term sealing performance.
- Excellent Abrasion & Tear Resistance - Withstands friction and mechanical wear in valve seats, pump components, and bearing applications.
- Customizable Formulation - Hardness (40–90 Shore A), color, and size can be tailored to specific application requirements.
Common Applications
- Check Valves & Control Valves - Sealing balls that regulate fluid flow in hydraulic and pneumatic systems.
- Pumps & Metering Devices - Precision balls for diaphragm pumps, piston pumps, and dosing equipment.
- Bearing & Linear Motion - Load-bearing balls in low-load, corrosion-sensitive bearing assemblies.
- Vibration Dampening & Noise Reduction - Elastic balls used as buffers, bumpers, and shock absorbers.
- Industrial Cleaning & Surface Treatment - Solid rubber balls for pipe cleaning, shot blasting, and tumbling media.
Quality Assurance
- Each batch undergoes dimensional inspection, hardness testing, and compression-set verification before shipment.
- Material traceability and compliance documentation (RoHS, REACH) available upon request.
- Custom packaging and private-label options supported for OEM/ODM partners.
