Product Descreiption
The Wheel Oil Seal is a critical component designed to prevent lubricant leakage and contaminant ingress in wheel hub assemblies, ensuring smooth operation, extended bearing life, and reduced maintenance costs for commercial vehicles, heavy machinery, and off-road equipment. Engineered for durability and reliability under extreme conditions, this seal is trusted by fleet operators, automotive manufacturers, and industrial users worldwide.
Key Applications
- Commercial Vehicles: Trucks, buses, trailers, and delivery vans.
- Heavy Machinery: Construction equipment (excavators, loaders), agricultural machinery (tractors, harvesters), and mining vehicles.
- Off-Road & Military Vehicles: ATVs, UTVs, armored personnel carriers, and logistics trucks.
- Passenger Cars: High-performance and all-wheel-drive (AWD) vehicles requiring robust wheel hub sealing.
Technical Specifications
- Material & Construction:
- Seal Lip:
- Nitrile Rubber (NBR): Standard option for general-purpose use (temperature range: -40°C to +120°C).
- Fluorocarbon Rubber (FKM/Viton): High-temperature variant (up to +200°C) for severe operating conditions.
- PTFE (Teflon)-Coated Lips: Ultra-low friction, high wear resistance, and dry-running capability for high-speed applications.
- Metal Case:
- Cold-Rolled Steel (SPCC): Cost-effective, corrosion-resistant for standard use.
- Stainless Steel (SS304/SS316): Marine-grade option for highly corrosive environments (e.g., coastal, salt-road, or chemical exposure).
- Spring: High-tensile stainless steel spring with anti-corrosion coating for consistent lip pressure.
- Seal Lip:
- Common Dimensions (Example: Standard Truck Wheel Hub Seal):
- Inner Diameter (ID): ~60–80 mm (2.36–3.15 inches).
- Outer Diameter (OD): ~90–110 mm (3.54–4.33 inches).
- Width: ~10–15 mm (0.39–0.59 inches).
- Design Type: Double-lip with dust exclusion ring, single pressure relief groove, and anti-extrusion backup ring for heavy-duty sealing.
- Performance Characteristics:
- Pressure Rating: Up to 0.5 MPa (72.5 psi) for standard wheel hub applications.
- Speed Rating: Up to 3,000 RPM (depending on seal type and lubrication).
- Temperature Range:
- NBR: -40°C to +120°C (-40°F to +248°F).
- FKM: -30°C to +200°C (-22°F to +392°F).
- Chemical Compatibility: Resistant to mineral oils, synthetic lubricants, grease, water, dust, and mild chemicals.
