Submit a request

Under-rail pad OP-356 is a railway fastening element installed between the rail foot and the baseplate. It is designed to reduce dynamic loads, vibrations, and impacts occurring during rolling stock passage. The pad also provides electrical insulation between the rail, the baseplate, and the sleeper. It is used on tracks with R-50 and R-65 rails.

Description and Design

The OP-356 pad is manufactured in accordance with TU 2539-161-01124323-2003 from reinforced, high-wear-resistant rubber. The pad design ensures tight contact between the rail foot and the baseplate, eliminating micro-movements and providing uniform pressure distribution. The elastic material maintains its shape and properties under long-term loads and temperature variations.

The shape corresponds to the rail foot profile of R-50 and R-65 rails;
Provides uniform load distribution and electrical insulation of metal components;
The material is resistant to moisture, oils, frost, and ultraviolet radiation;
Effectively reduces vibrations and noise generated by rolling stock movement;
Service life: at least 10 years under standard operating conditions.

Application

OP-356 under-rail pads are used as part of elastic railway fastening systems such as KB, KBL, KP, and similar designs. They are installed between the rail and the steel baseplate on reinforced concrete sleepers. The pads are applied in the construction, repair, and modernization of mainline and industrial railway tracks, including stations and turnout areas.

Advantages of OP-356 pads:

Reduction of dynamic loads on track superstructure elements;
Extended service life of rails, baseplates, and sleepers;
High electrical insulation properties and moisture resistance;
Resistance to cyclic loads and temperature fluctuations;
Compliance with Ukrzaliznytsia requirements and TU 2539-161-01124323-2003.

Supply and Packaging

We supply OP-356 under-rail pads in batches of 100 pcs or more;
Each batch undergoes inspection of geometric dimensions and hardness;
Supply as part of complete KB, KBL, and KP railway fastening systems is available;
Delivery across Ukraine by road or rail transport from Prombudkoliya warehouses.
