BC2‑0098 Double‑row Cylindrical Roller Bearing

160-270-170

Product Introduction

BC2‑0098 is a custom‑design double‑row cylindrical roller bearing for railway traction motor service, manufactured to FAG railway specification. It is produced from high‑purity vacuum‑degassed chrome bearing steel, featuring two rows of precision‑ground cylindrical rollers for outstanding radial load capacity and high rigidity under alternating heavy‑load conditions.

This bearing adopts separable inner ring, outer ring and roller‑cage assembly. It can be easily mounted, dismounted and inspected on‑site, which meets railway maintenance requirements. The standard cage is solid machined brass, providing stable roller guidance, low friction heat generation and reliable high‑speed performance.

Normally used as floating (non‑locating) bearing position inside traction motor, it permits axial displacement caused by thermal expansion of rotor shaft while maintaining precise radial support. It resists shock, vibration and frequent variable‑speed working conditions of electric locomotives, multiple‑units and metro vehicles. Insulated coating option is available to protect against electric current erosion in traction motor systems.

Key Features

‑ Double‑row cylindrical roller structure, excellent heavy radial load capacity ‑ Separable components for convenient installation, removal and maintenance ‑ High‑strength machined brass cage for high‑speed stable operation ‑ Tolerates shaft axial thermal expansion for floating‑end application ‑ Good shock‑resistance and anti‑vibration performance for railway drive environment ‑ Optional insulation coating against electrical current damage

Application

Applied in railway traction motors for electric locomotives, EMU, metro and light rail vehicles; also suitable for locomotive auxiliary drive systems requiring large radial load and floating compensation.
