Performance Characteristics
1. High-efficiency sealing: Utilizing a double-lip or multi-lip design, it effectively prevents grease leakage from the wheel hub and blocks moisture, dust, and road impurities from entering the bearing cavity.
2. Wear and temperature resistance: Optimized for the high-temperature environment generated by frequent truck braking. NBR material typically withstands temperatures up to 120°C, while FKM can withstand temperatures exceeding 200°C.
3. Stability: Exhibits excellent grease resistance and anti-aging properties, ensuring consistent sealing elasticity even under harsh road conditions.
Maintenance Tips:
Installation Alignment: Use a specialized tool to press the seal vertically during installation. Never strike the sealing lip directly with a hammer, as this may deform the oil seal and cause premature leakage.
Lubrication: Apply a small amount of grease to the sealing lip before installation to reduce dry friction wear during initial startup.
Regular Inspection: If oil stains are found on the inside of the wheel hub, replace it immediately. Otherwise, oil contamination of the brake pads may lead to brake failure and bearing damage.
Replacement: When replacing bearings or performing a second-level maintenance service, it is recommended to replace the oil seal simultaneously.
