A tubeless rim is a rim structure that achieves tyre sealing without the need for a traditional inner tube. It forms a sealed space through the precise fit between the rim and tyre, and achieves sealing by the compression of the tyre bead and rim after inflation. This rim is suitable for use in port automation machinery, which requires high reliability and maintenance-free operation. Tubeless rims paired with explosion-proof tyres can achieve two years of maintenance-free operation. The tubeless design reduces inner tube wrinkling and wear during high-speed operation, making it suitable for high-speed mobile machinery.
It is specifically designed for heavy construction vehicles such as loaders and graders to install tubeless tires. The "5-piece set" refers to the entire system comprising the following five independent components that work together to form a robust, inflatable sealed chamber:
Wheel rim base: The main component connecting to the axle.
Retaining ring: Installed on one side of the wheel rim to secure the tire.
Lock Ring: A critical safety locking ring designed to securely lock the retaining ring into the rim groove.
O-ring：Installed in the groove of the wheel rim, it provides a core airtight seal.
Valve stem assembly：Installed in dedicated mounting holes for inflation and pressure measurement.
Product Parameters
Product Advantages
Highly secure
Tubeless tires eliminate the risk of blowouts caused by friction-generated heat in inner tubes. After punctures, they leak air slowly, providing more time for repair.
Excellent heat dissipation
The tire makes direct contact with the wheel rim, facilitating heat transfer from the tire to the metal rim for dissipation. This configuration is suitable for low-speed, heavy-load operating conditions.
Lightweight yet strong load-bearing capacity
Compared to traditional tubed rim assemblies, it is lighter in weight and offers higher structural strength.
Easy to maintain
Tire repair can be performed directly on the vehicle without removing the wheel rim.
