Product Introduction
1639605 C-01 is a high-precision sealed double-row tapered roller bearing unit specially designed for railway and urban rail axle box systems, fully compliant with EN12080 railway industry standards. It is manufactured from high-purity vacuum-degassed carburized bearing steel with strict P5 precision machining and professional heat treatment, delivering excellent structural rigidity and contact fatigue resistance for long-cycle railway operation.
This integrated bearing unit can withstand heavy combined radial loads and bidirectional axial thrust loads generated during vehicle curve running, snake vibration and track impact. Adopting optimized logarithmic roller crowning design, it effectively eliminates edge stress concentration, greatly improving shock resistance and operational stability under harsh and variable load working conditions. Equipped with a multi-lip integrated sealing system, it perfectly resists dust, rainwater, sand and other environmental contaminants, avoiding internal grease deterioration and bearing wear.
Supplied as a pre-assembled integral cartridge structure, the bearing requires no complicated assembly adjustment, greatly simplifying on-site installation, overhaul and replacement procedures, reducing railway vehicle downtime and maintenance costs. It maintains stable lubrication performance and ultra-long service life adapting to long-distance continuous running of rail transit equipment.
