Shock Absorber Dust Cover/ Strut Bellow

Performance values can be adjusted through compound formulation and structural design.

Why Choose Our Neoprene Rubber Bellows
Our company has extensive experience in manufacturing rubber bellows and rubber dust boots for industrial and automotive applications. Stable neoprene compound formulation ensures consistent oil resistance, flame retardancy, and mechanical performance. Precision tooling supports complex bellows geometries and repeatable dimensions, while strict quality control is applied throughout material preparation, molding, and final inspection. We support OEM projects, replacement parts, and fully customized designs based on drawings or samples.

Product Use:
Industrial and Marine Applications: Used in bellows, gaskets, and protective covers where exposure to oils, chemicals, and outdoor elements is expected.
Construction Industry: Common in structural joints and weatherproofing applications.
Electrical Applications: Neoprene bellows are used in environments requiring flame retardancy.

Neoprene rubber bellows are widely used in automotive steering systems, suspension joints, and under-hood components where oil exposure and movement are present. They are also applied to hydraulic cylinders, pneumatic actuators, and industrial machinery that require protection for sliding or reciprocating parts. Additional applications include mechanical linkages, electrical assemblies, and equipment where dust protection, oil resistance, and flame retardancy are important.

In industrial environments, these components are commonly used as rubber dust boots, flexible rubber bellows, and protective rubber covers to extend equipment service life.

Oil and Chemical Resistance
Neoprene rubber exhibits good resistance to oils, greases, fuels, and a wide range of industrial chemicals. This property allows the rubber bellows to perform reliably in lubricated environments and machinery where contact with oils is unavoidable.

Flame-Retardant Performance
Neoprene is naturally flame resistant, which improves safety in applications involving electrical components, mechanical systems, or industrial equipment where fire resistance is a consideration.

Flexible Bellows Structure
The multi-rib accordion design supports repeated expansion and compression without structural collapse. The bellows maintains consistent coverage over moving parts while allowing smooth motion during operation.

Stable Performance in Moderate Temperatures
Neoprene rubber bellows operate effectively within a temperature range of -35°C to +120°C. Elasticity and mechanical strength remain stable during thermal
cycling and prolonged use.

Mechanical Strength and Wear Resistance
The material offers good tensile strength and abrasion resistance, enabling the bellows to withstand vibration, repeated motion, and mechanical stress over time.

Controlled Weather and Ozone Resistance
Neoprene provides moderate resistance to weathering and ozone exposure, making it suitable for indoor applications and limited outdoor use where extreme UV resistance is not required.

What is the primary function of a rubber bellows or dust boot?
A rubber bellows protects moving components from dust, debris, oil, moisture, and external contamination during operation.

Why is neoprene rubber used for bellows?
Neoprene provides a balanced combination of oil resistance, chemical stability, flame retardancy, and mechanical durability, making it suitable for industrial environments.

Can neoprene rubber bellows be used outdoors?
They offer moderate weather resistance and are suitable for limited outdoor exposure. For long-term outdoor use, materials such as EPDM may be more appropriate.

What types of movement can this bellows accommodate?
Depending on design, the bellows can support axial, reciprocating, and limited angular movement.

Are custom sizes and designs available?
Custom dimensions, rib configurations, wall thicknesses, and hardness levels can be produced according to drawings or samples.
