1. Product Introduction

2. Structural Features 

Full rubber-coated metal skeleton: High-strength carbon steel insert, fully wrapped by rubber, no metal exposure, anti-corrosion, stable outer diameter interference fit, no damage to the housing bore.

• Double lip design: Main sealing lip + auxiliary dust lip, forming a labyrinth effect, effectively isolating internal oil and external dirt.
• Self-tightening garter spring: Provides continuous radial pressure, adapts to shaft eccentricity and wear, maintains long-term sealing performance.
• Precision lip geometry: Optimized lip angle to form a stable micro oil film, reduce friction heat and wear, extend service life.
• Standard installation size: Fully compatible with international standard bore and shaft fits (H7/h6), easy press-fit installation.

4. Performance Advantages

• Cost-effective & globally recognized: Low comprehensive cost, stable supply chain, suitable for large-scale procurement in Europe, America, Southeast Asia, Middle East and Africa.
• Good oil resistance: Stable performance in common mineral oil systems, no swelling, no hardening, no cracking.
• Strong anti-pollution ability: Double lip structure effectively blocks dust and water, suitable for outdoor machinery and vehicles.
• Low friction & low heat: Stable oil film reduces heat generation, avoids early failure caused by high temperature.
• Wide dimensional range: Shaft diameter φ6~φ200mm, width 4~15mm, can meet most general sealing needs.

5. Application Fields

• Automotive: Crankshaft front/rear seal, camshaft seal, gearbox input/output shaft seal, wheel hub, differential.
• General industrial: Electric motor, fan, water pump, air blower, agricultural machinery, small hydraulic equipment.
• Aftermarket: Universal replacement parts for light and medium-duty equipment worldwide.
