Harmonic reducer oil seal

Dual Seal Protection Leakage Prevention: The main lip is equipped with a self-tightening spring to lock in internal grease (e.g., lithium-based grease), reducing the risk of leakage-related faults by over 30% and ensuring transmission accuracy. Contamination Prevention: Double-lip/multi-lip structure + dust lip blocks dust, cutting fluid and moisture, protects precision components such as flexsplines, and is suitable for severe operating scenarios including welding and spraying.

Low Friction & Adaptability Low-Torque Design: Optimized lip curvature and surface treatment ensure dynamic friction coefficient fluctuation ≤ ±3%, reducing energy consumption and meeting the low-power requirements of collaborative robots. Oscillation Followability: The elastic lip structure compensates for deflection, adapts to high-frequency start-stop and reciprocating oscillation conditions of harmonic reducers, and prevents lip uneven wear.

Resistance to Severe Conditions & Long Service Life Weather-Resistant Materials: Mainstream FKM sealing lips withstand temperatures ranging from -20℃ to 200℃, featuring excellent anti-aging and oil-resistant performance. VMQ (for food/medical applications) or PTFE (for ultra-low temperature/chemical corrosion scenarios) options are available. Reliable Structure: Thin steel plate/stainless steel framework ensures structural rigidity; self-tightening springs continuously compensate for wear, delivering a service life of ≥ 8000 hours under normal operating conditions.

Compact Installation Small Cross-Section Design: Tailored for the narrow cavities of harmonic reducers; the external thread facilitates installation and compensates for cavity ovality.

Transmission Accuracy Assurance: Reliable sealing prevents gear/bearing wear caused by grease leakage, maintaining the high precision of harmonic drive (repeat positioning accuracy ≤ ±0.01mm).

Service Life & Maintenance Optimization: Long-service-life design combined with easy-installation structure extends maintenance intervals and reduces downtime and replacement costs.

Energy Consumption & Adaptability Upgrade: Low-torque and lightweight features cut down joint drive energy consumption, ideal for the compact design of humanoid/collaborative robots.

Customized Adaptability: Lip structure, material and spring configuration can be customized according to shaft diameter (15–100mm) and operating conditions (temperature/medium).
