Product Description

Our GOST Standard Fixed Cover is a precision engineered component specifically designed for Russian railway axle box assemblies used in heavy duty freight wagon bogies. This fixed cover serves as the opposite side sealing component to the fastening cover, providing essential protection for the axle bearing assembly against dust, moisture, and mechanical damage .

18-100 Bogie Compatibility

This fixed cover is designed for the Russian 18-100 bogie, widely used across 1520 mm gauge railway networks in Russia, Ukraine, and other CIS countries . It is an integral component of the axle box unit that connects the wheelset to the bogie frame while supporting the vehicle's weight and allowing smooth wheel rotation .

Heavy Duty Construction

Manufactured from high strength cast steel ZG230-450 using precision casting methods, the fixed cover ensures reliable sealing performance under heavy load and harsh operating conditions . The material provides excellent durability and resistance to impact loads encountered during heavy haul freight operations.

Surface Protection

All fixed covers receive anti-rust oil treatment to ensure long service life even in demanding environmental conditions, protecting against corrosion and wear during extended freight operations .

Key Components and Part Numbers

The complete axle box assembly includes both fixed cover and fastening cover components. The fixed cover is identified by part number 100.10.002 and works in conjunction with the fastening cover (100.10.052-0) to provide complete sealing of the axle bearing housing .

GOST Compliance

Our fixed cover meets the requirements of GOST 34385-2018, the interstate standard for axle-boxes and adapters for wheelsets of freight wagon bogies, which establishes general technical specifications and quality requirements . This standard covers axle boxes and their components, including covers, for two-axle three-element bogies per GOST 9246 .
