Bolster springs are commonly used in the automotive industry. They are important for the suspension systems of heavy-duty vehicles, like trucks, trailers, and railway cars. Their unique composition and design offer numerous benefits that significantly enhance vehicle performance and durability.

Production of Bolster springs

RNTICO has over 10 years of experience in the production of bolster springs. The production of bolster springs involves a sophisticated combination of steel and rubber materials, which creates a highly durable and long-lasting product. This process typically incorporates vulcanization, a method where rubber is cured with heat and sulfur. Vulcanization enhances the rubber’s strength and elasticity, ensuring optimal performance.

The high-strength steel component provides essential structural support, while the customized rubber element offers flexibility and resilience. This synergy between metal and rubber is what gives bolster springs their distinct advantages.

In terms of applications

Bolster springs are essential in heavy-duty vehicles such as trucks, trailers, and railway cars. Their main functions include:

Flexibility: The rubber component allows the bolster spring to absorb shocks and vibrations from the road surface. This not only enhances ride comfort for passengers but also reduces stress on the vehicle’s chassis.

Load-Bearing Capacity: The metal part of the bolster spring provides the necessary strength to support the vehicle’s weight. It helps maintain proper suspension alignment, ensuring safe and stable vehicle operation.

Durability: The combination of rubber and metal creates a highly durable product that resists wear and tear. Bolster springs can withstand heavy loads and harsh operating conditions, making them a reliable choice for long-term use.

Vibration Isolation: The rubber bonding in the bolster spring effectively isolates vibrations caused by road irregularities. This prevents vibrations from transferring to the vehicle’s chassis, contributing to a smoother and more stable ride.

​Noise Reduction: By absorbing and dampening vibrations, bolster springs help reduce noise generated by the suspension system. This results in quieter vehicle operation, enhancing the overall driving experience.

Furthermore, rubber bolster springs are also employed in industrial machinery and equipment that require shock absorption and vibration isolation. Their resilience and durability make them suitable for various applications involving heavy loads and mechanical stresses.

Bolster springs are important for better suspension performance. They improve ride comfort and help heavy-duty vehicles last longer. Their use reduces maintenance and operating costs, making them a cost-effective solution for vehicle manufacturers and operators.

RNTICO makes many types of bolster springs for different vehicle models. This includes VOLVO, BENZ, Hyundai, HOWO, and other heavy trucks.
