Product Description

1. Product Overview

535191/574613 is TQO structure four row tapered roller bearing, widely used for metallurgical rolling mill roll neck. Complete set consists of two double cones, one double outer cup, single outer cup plus inner & outer spacer components.

It can withstand extremely heavy combined radial load and bidirectional axial load simultaneously. Built-in spacer with lubrication through-holes, ensures uniform lubricant distribution between roller rows. Strict serial matched assembly, cannot randomly mix spare parts. Open construction supports continuous circulating oil lubrication. Mainly applied on hot rolling mills, cold rolling mills, heavy metallurgical machinery and low-speed high-load industrial rotary equipment.

Formal quotation will be sent within 24 hours upon your inquiry.
