Polyurethane screen parts(Rail Seat)

It is usually installed on the frame or support structure of the screen mesh, used to support and fix the screen mesh, making installation and replacement convenient, and reducing downtime.

Polyurethane Rail Seats are critical polyurethane screen parts used in vibrating screens to support and fix screen panels or rails.
They are designed to absorb vibration, reduce impact, and protect screen structures from wear and damage during operation.

Compared with metal or rubber rail seats, polyurethane rail seats provide better elasticity, longer service life, and reduced maintenance costs in harsh screening environments.

Product Description

Polyurethane screen rail seats are installed between the screen deck and supporting rails of vibrating screens.
Their main function is to provide stable support for screen panels while reducing vibration, noise, and metal-to-metal contact.

Made from high-quality cast polyurethane, rail seats combine excellent abrasion resistance with elastic cushioning, making them ideal for mining, quarrying, and aggregate screening applications.

They help extend the service life of both screen panels and screen frames while improving overall screening efficiency.

Key Features

High Elasticity & Shock Absorption
Effectively reduces vibration and protects screen structures

Excellent Wear Resistance
Longer lifespan than rubber and metal rail seats

Noise Reduction
Minimizes operational noise caused by vibration and impact

Secure & Stable Support
Ensures proper fixation of screen panels and rails

Custom Design Available
Dimensions, hardness, shapes, and colors can be customized

Typical Applications

Polyurethane rail seats are widely used in:

Vibrating screens

Mining screening equipment

Aggregate and quarry screening systems

Coal, sand, and stone processing plants

Bulk material handling systems

Installation Position

Rail seats are typically installed:

On screen support rails

Between the screen deck and rail beam

At contact points where vibration and impact are concentrated

The polyurethane rail seat acts as a buffer and support component between screen panels and screen frames.
