LBH Type Hydraulic Cylinder Dustproof Oil Seal | Double-Lip Protection for Extreme Conditions
Product Overview
The LBH-type hydraulic cylinder dust seal is a bidirectional-acting dust-proof component mainly made of nitrile butadiene rubber, featuring an acute-angle edge double-lip structure. It can effectively scrape dirt off the surface of the piston rod while retaining an oil film. It is widely used in hydraulic and other reciprocating motion systems to block impurity intrusion, protect equipment, and maintain sealing performance.
Mining Equipment - Drilling rig cylinders, roof support systems
Material Handling - Forklift hydraulics, conveyor system actuators
Marine Applications - Ship steering systems, hatch control cylinders
Why Choose LBH Dustproof Oil Seals?
Dust-proof sealing with high efficiency: The dual-lip design can strongly scrape off impurities, while also retaining oil film to reduce wear, protecting the hydraulic system.
Strong adaptability to working conditions: Made of NBR material, it is oil-resistant and wear-resistant, compatible with various media, and can work stably in high-pressure, high-temperature, and low-temperature environments.
Easy installation and maintenance: Compact structure that can be directly installed into grooves, with a full range of specifications for convenient replacement, reducing equipment downtime.
Outstanding cost-performance: Reliable performance with competitive pricing, strong durability to reduce replacement frequency, and lower long-term maintenance costs.
Installation Guidelines
Proper Installation Procedure
Clean Work Area - Ensure clean environment free from contaminants
Lubricate Properly - Apply compatible lubricant to seal lips and shaft
Use Installation Tools - Employ proper mandrels to prevent damage during pressing
Correct Orientation - Install with dust lip facing external environment
Verify Placement - Ensure seal is fully seated against housing shoulder
Common Installation Mistakes to Avoid
Using sharp or improper installation tools
Dry installation without lubrication
Misalignment during pressing operation
Damaging seal lips on sharp edges or threads
