- Variable-diameter bellows: Ø23×Ø65, Ø12×Ø27, Ø10×Ø22, Ø6×Ø15, Ø8×Ø18
- Straight bellows: Ø32, Ø26, Ø30
- 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.
