Submit a request

Sleeper pad PNB-3 (CP-328) is an elastic element of railway fastening systems installed between a reinforced concrete sleeper and a rail baseplate. It is designed to reduce dynamic impact loads, vibrations, and noise, as well as to provide electrical insulation between the rail and the sleeper. The pad is used on tracks with R-50 and R-65 rails on mainline and industrial railways.

Description and Design

The PNB-3 (CP-328) sleeper pad is manufactured in accordance with TU 2539-161-01124323-2003 from high-strength reinforced rubber. The material maintains its elasticity and shape under temperature fluctuations and exposure to oils, moisture, and ultraviolet radiation. The pad design ensures uniform pressure distribution under the rail base and prevents damage to the concrete sleeper.

Elastic structure absorbs impact and vibration loads from rolling stock;
The pad does not absorb moisture and is resistant to cracking;
Thickness and shape are optimized for uniform force transmission through the baseplate;
The material is electrically non-conductive, providing insulation of the sleeper;
Service life is at least 10 years under normal operating conditions.

Application

PNB-3 sleeper pads are used in railway fastening systems such as KB, KBL, KP, and similar assemblies for laying R-50 and R-65 rails. They are applied in the construction and maintenance of general-purpose and industrial railway lines, including mainline, station, and turnout sections. The pad is installed under the baseplate between the rail and the sleeper, providing an elastic and insulating interface.

Advantages of PNB-3 (CP-328) sleeper pads:

Reduction of vibrations and impact loads on sleepers and baseplates;
Extended service life of reinforced concrete sleepers and track components;
Resistance to aging, moisture, ultraviolet radiation, and low temperatures;
Retention of elastic properties under repeated load cycles;
Compliance with Ukrzaliznytsia requirements and TU 2539-161-01124323-2003.

Supply and Packaging

PNB-3 (CP-328) sleeper pads are supplied in batches of 100–500 pcs per package;
Each product undergoes inspection of geometric dimensions and hardness;
Supply as part of complete railway fastening kits is available;
Delivery across Ukraine by road or rail transport from Prombudkoliya warehouses.
