Product Introduction
NNJ5232X3 is a heavy-duty double-row cylindrical roller bearing specially designed for railway freight wagon axle boxes. It adopts a separable inner and outer ring structure, equipped with high-precision machined brass cage and premium chrome bearing steel.
This bearing features extremely high radial load capacity, excellent structural rigidity and superior shock resistance. The optimized internal structure perfectly adapts to heavy alternating loads, frequent start-stop operation and long-distance continuous running. It mainly undertakes radial loads and allows limited axial displacement, ensuring high operational stability and long service life under harsh railway working conditions.
Application
Widely applied in railway freight wagon axle box assemblies and heavy-duty rail vehicle wheel set support parts, dedicated for heavy-load railway freight transport scenarios.
