Four-Row Cylindrical Roller Bearings BC4-0109

Four-Row Cylindrical Roller Bearings BC4-0109

The BC4-0109 is a four-row cylindrical roller bearing with a 190mm bore and 270mm outer diameter, designed for heavy-duty applications. Its 200mm width provides stability under combined loads, handling up to 405,000 lbf dynamically.

Made from high-quality materials, it supports both grease and oil lubrication, ensuring smooth operation in temperatures from -30°C to 110°C. The chamfered edges (2.1mm) on both inner and outer rings make installation easier.

This bearing is interchangeable with SKF models, offering a reliable replacement option. Ideal for industrial machinery like rolling mills or large gearboxes where high radial loads are common.

Compliant with RoHS and REACH standards, it’s built for durability and long service life in demanding environments.
