Double row cylindrical roller bearings

Contact Now

Double Row or Two Row cylindrical roller bearings are designed for heavy loads that can’t be serviced with a single row bearing. The additional row of rollers allows for the increased radial loads. Our double row cylindrical bearings are typically metric dimensioned with a machined brass cage. The cage is a one-piece roller riding brass finger cage that promotes smooth rolling. They are industry interchangeable with the same size designation. They will be supplied with C3 Internal Radial Clearance unless specified. Bearings with tapered bore, “K” suffix and P5 clearance can be supplied upon request. Applications for two row cylindrical bearings include lathes, gearboxes, and pinion stands.
