DOUBLE-ROW CYLINDRICAL ROLLER BEARINGS
Double-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. These 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 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 include lathes, gearboxes, and pinion stands.
Some cylindrical roller bearings have no ribs on either the inner or outer ring, so the rings can move axially relative to each other. These can be used as free-end bearings. Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.Pressed steel or machined brass cages are generally used, but sometimes molded polyamide cages are also used.
