Product Overview

BWK cylindrical roller bearings use cylindrical rollers with linear contact between the rollers and raceways, providing high radial load capacity and reliable rigidity.

Different ring and flange designs are available to meet radial load, axial positioning and shaft displacement requirements. The separable structure also makes installation and maintenance more convenient.

BWK provides single-row, double-row, metric and inch-size cylindrical roller bearings for different industrial applications.
