Rubber Bellows and Dust Boots Advantages

Dust and water protection: Composite structures or bellows designs effectively block over 90% of particles larger than 50 μm and prevent water, mud, and oil from entering critical components, avoiding wear and corrosion.
Durability and wear resistance: Materials are wear-resistant, suitable for high-frequency movement in automotive suspensions and construction machinery. Certain models, such as steering ball joint dust boots, can last up to 100,000 km while maintaining stability within -40℃ to 150℃.
Reliable sealing: Dynamic sealing designs reduce dust accumulation, and surface groove structures lower particle buildup risk by up to 50%, keeping internal components clean.
Flexible installation: External products allow quick removal and replacement for maintenance, while internal products occupy minimal space (0.3–1.2 mm thickness), ideal for precision instruments.

Applications

Motorcycle shock absorber dust boots

Constant velocity joint (CV joint) dust boots

Gas spring dust boots
