Secondary Suspension Products

Explore our range of secondary suspension components designed to support vibration isolation, controlled movement and reliable performance across railway coach and bogie assemblies.

Ball Joint Roll Link

Essential for stabilizing roll motions in LHB FIAT Bogie, this robust ball joint ensures optimal lateral balance and ride comfort.

Traction Centre Elastic Joint

Designed to absorb dynamic forces and vibrations, providing flexibility and stability in the central traction system of the bogie.

Lateral Bump Stop

A resilient rubber component that limits lateral movements, ensuring controlled dynamics and protecting the bogie structure.

Rubber Pad for Longitudinal Bump Stop

Specially designed to limit longitudinal motion, protecting the bogie and enhancing ride stability.

Stabilizer Link Assembly

The stabilizer link, also known as a sway bar or anti-roll bar, connects both sides of the suspension system in a bogie to reduce body roll and improve stability during cornering or uneven terrain. It distributes weight evenly across the bogie, maintaining balance and traction, while also allowing controlled independent suspension movement to handle uneven surfaces effectively.

Central Pivot Bush

Side Bumper

The side bumper in a bogie, or lateral buffer, absorbs lateral forces during train operations, stabilizing the bogie and reducing swaying on curves or uneven tracks. It enhances passenger comfort by dampening lateral movements and protects bogie components from impacts and reduces noise and vibration, ensuring structural integrity and a quieter environment.

Traction System Products

Explore our range of traction system components designed to support efficient force transmission, controlled movement, vibration isolation and reliable performance across demanding railway applications.

Ball Joint Traction Lever

High-performance ball joint connecting the traction lever to the bogie, enabling precise and smooth power transmission with enhanced durability.

Application: Passenger Coach – LHB Coach

Motor Suspension Bush

The motor suspension bush in a traction motor dampens and isolates vibrations, reducing noise and protecting other bogie components from wear and tear. It ensures proper alignment and stability of the motor, preventing excessive movement or misalignment. By minimizing stress and fatigue, it extends the lifespan of the motor and related components.

Application: Vande Bharat (Train 18)

Motor Suspension Pad

The motor suspension pad in a traction motor isolates vibrations, reducing noise and preventing their impact on other components, improving ride comfort. It absorbs shocks from track irregularities or abrupt movements, protecting the motor and bogie from damage. Additionally, it distributes loads evenly, reducing stress on components and enhancing their durability and lifespan.
Application: Vande Bharat (Train 18)

Traction Rod Assembly

The traction rod assembly with a spherical bearing transmits traction and braking forces between the bogie and wheelsets, enabling propulsion and deceleration. The spherical bearing allows for articulation and misalignment, ensuring efficient power transfer while accommodating track variations and curves. It enhances stability, reduces stress on components, and improves ride quality by maintaining proper alignment and minimizing wear.
Application: Vande Bharat (Train 18)

Spheribloc

In the WAP7/WAG9 electric locomotive, spheriblocs are used to provide longitudinal guidance for the axle box housing while allowing controlled lateral movement, ensuring smooth operation of the axle guide rods. They are also fitted at both ends of the torque arm to support the traction motor mounting plate and connect the traction motor support arm to the bogie frame and center transom mounting lug, ensuring stability and vibration damping.
