rear swing arm joint boot

Introduce

The rear swing arm joint boot serves as protection for the joint. It is mostly utilized in off-road vehicles like as motorbikes and ATVs. A crucial part that joins the rear suspension system to the frame, enabling smooth movement over uneven ground and suspension control, is the rear swing arm joint.

Technical data

Certification standard

• ISO 9001: This is an international standard that addresses quality management system criteria. ISO 9001-certified products fulfill certain quality management criteria.
• ASTM D2000: An American Society for Testing and Materials (ASTM) standard that specifies the physical, chemical, and other associated qualities of rubber goods.
• SAE J200: A Society of Automotive Engineers (SAE) standard that establishes the performance standards for rubber products in automotive and vehicle applications.
• RoHS: Restriction of the Use of Certain Hazardous Substances directive of the European Union, which establishes limits on materials used in electronic and electrical equipment, including rubber goods.
• REACH stands for the EU Registration, Evaluation, Authorization, and limitation of Chemicals Regulations, and it governs the registration and limitation of chemical compounds on the EU market. It also applies to chemical substances used in rubber goods.

Advantage and function

1. Safeguard the rear swing arm joint: The rear swing arm joint connects the rear suspension system to the frame. The guard’s primary role is to protect the rear swing arm joint from damage and contamination from the outside environment. It keeps dust, dirt, moisture, mud, and other impurities out of the joint, decreasing wear and damage.
2. Extended service life: The rear swing arm joint boot serves to lengthen the service life of the rear swing arm joint by providing specific protection. It keeps impurities out of the joint and lowers friction and wear, decreasing the joint’s effect from regular use and hostile surroundings.
3. Lubrication and friction reduction: Some rear swing arm joint boots include built-in grease or coating that can provide effective lubrication and friction reduction between joints. This keeps the joints active and functional, which improves suspension performance.
4. Corrosion and Oxidation Protection: The guard also protects against corrosion and oxidation. It protects joints from moisture, chemicals, and other corrosive media, lowering the danger of corrosion and oxidation caused by time and environment.
5. Simplified Maintenance and Cleaning: The rear swing arm joint boot makes maintenance and cleaning easier. It prevents dirt and silt from clinging to the joint, making cleaning faster and easier.

Conclusion

The rubber boot for the rear swing arm joint is a crucial part of off-road vehicles, connecting the rear suspension system to the frame. It is made of rubber with a density of 1.23-1.24 g/cm³, hardness of 40-90 Shore A, tensile strength of 10-20 MPa, and elongation at break of 100-600%. It meets various certification standards, including ISO 9001, ASTM D2000, SAE J200, RoHS, and REACH. The boot protects the joint from damage and contamination, prolonging its service life. It also provides lubrication and friction reduction, reducing friction and wear. It also protects against corrosion and oxidation, making maintenance and cleaning easier.
