Railway Rubber Bump Stops & Secondary Rubber Mats
Limit Buffering and Elastomeric Isolation Pads for Bogies & Vehicle Frames
Overload Limiting & Secondary Vibration Isolation
Protect your bogie structures and suspension systems from extreme shock overloads with our durable railway rubber bump stops and elastomeric primary rubber mats. Designed to provide progressive cushioning during large displacements, our lateral and vertical bump stops act as safety limits that prevent harmful metal-to-metal contact during extreme sway or bounce.
Concurrently, our heavy-duty rubber spring mats and buffer pads are placed beneath metallic coil springs to mitigate high-frequency acoustic vibrations and distribute localized stresses evenly. Formulated from premium weather-resistant, oil-proof elastomers, our limit bumpers offer reliable performance under extreme climate and load conditions.

Where Each Rubber Component Does Its Job
Bogie Lateral & Vertical Rubber Bump Stops
Lateral bump stops limit sway between the bogie frame and carbody, while vertical bump stops limit bounce travel. Both act as safety limits that absorb shock before metal-to-metal contact can occur. Rubber stop blocks are available in conical and cylindrical forms, with or without metal mounting bases.

Primary & Secondary Suspension Rubber Mats
Primary rubber mats and spring mats sit beneath metallic coil springs to reduce high-frequency noise and spread localized stress evenly. Secondary rubber mats and buffer pads serve the carbody-side suspension positions as a further vibration isolation layer.

Progressive Rubber Buffer Blocks & Protectors
Textured or wave-profile rubber buffer blocks provide rising stiffness as they compress, giving soft initial contact and firm end-of-travel protection for bogie and vehicle frame structures under heavy load.

Where Bump Stops & Rubber Mats Sit on the Bogie
Primary mats sit under the axlebox coil springs, secondary mats and buffers at the bolster and carbody interface, and lateral/vertical bump stops at the travel limits of the bogie frame.
- Primary Suspension
- Rubber spring mats beneath coil springs at the axlebox.
- Secondary Suspension
- Rubber mats and buffer pads at the bolster and carbody interface.
- Travel Limits
- Lateral and vertical bump stops limiting extreme sway and bounce.
