Product Description
Product Overview
A hydraulic railway damper is a device designed to absorb and reduce shock impulses incurred when a railcar is in motion. Dampers also help reduce noise and track wear. They operate on diesel and electric locomotives, passenger mainline coaches, and diesel and electric multiple-unit trains. It can be divided into 4 categories. Primary Vertical damper, Secondary vertical/lateral damper,Yaw damper and Coupling damper. For here it is primary vertical damper(axle box damper),used to control vertical movement between axle box and bogie. I.E nodding vibration.

There are other 3 categories as below:
Primay oil damper
it consists of vertical and lateral oil damper, which aims to control nodding vibration and bouncing vibration between carbody and bogie.
Yaw damper
Yaw dampers are a special feature of rail vehicles. They control the sine wave effects of the bogie, increasing safety at medium and high speeds.
Coupling damper
A coupling damper improves the quality and precision of your braking when towing by assisting with the gradual applying of the brakes both on and off.
