Product Introduction
232726 (30-232726 / 36-232726 E2M) is a professional single-row cylindrical roller bearing specially designed for railway locomotive and freight wagon axle box systems. Made of high-purity GCr15 chrome bearing steel, it adopts optimized internal roller configuration and high-rigidity structural design. This bearing features ultra-high radial load capacity, low friction coefficient and excellent fatigue resistance, fully adapted to long-term continuous operation and frequent variable load conditions of railway equipment.
It adopts high-precision brass cage (optional nylon/steel cage) to ensure stable roller operation and strong anti-shock performance. With precise manufacturing tolerance and reliable structural stability, it effectively resists vibration and impact during high-speed railway operation, delivering long service life and high operational safety under harsh and continuous working conditions.
Application
Exclusively applied for railway freight wagon axle boxes, locomotive wheel set support systems and railway rolling stock. Ideal for heavy-load, high-speed and long-distance railway transportation working scenarios, widely used in railway transit heavy-duty supporting equipment.
