Double row cylindrical roller bearing: high rigidity and heavy load efficient transmission bearing

Double-row cylindrical roller bearings are a heavy-duty category in the cylindrical roller bearing family with two rows of cylindrical rollers as the core. The core feature is that through the line contact design of double-row rollers and the inner and outer ring raceways, they can achieve higher radial load-bearing capacity and rigidity than single-row models in the same installation space. They also have axial compensation functions and are suitable for scenes with strict radial load and stiffness requirements, such as machine tool spindles, rolling mills, and mining equipment. They are key support components in heavy industry and precision manufacturing.

From a structural point of view, this type of bearing is mainly composed of four parts: an outer ring (with double rows of linear raceways), an inner ring (with double rows of linear raceways), two rows of cylindrical rollers, and a cage. Some models include ribs or seals. The core design highlight is the double-row roller layout: the two rows of rollers are symmetrically distributed and precisely fit the double-row raceways of the inner and outer rings. The contact area is 80%-100% larger than that of single-row cylindrical roller bearings, which can transmit radial loads more evenly; the rollers mostly adopt a convex design to reduce Edge stress is concentrated to improve wear resistance; cages are divided into brass cages (suitable for high speed and high temperature, such as machine tool spindles) and engineering plastic cages (low noise, lightweight, such as motors) according to working conditions. Some heavy-duty models use integral steel cages to enhance impact resistance. According to the separability of the structure, the common types are "separable inner ring" or "separable outer ring". There is no need to disassemble the entire transmission system during assembly and disassembly, which facilitates maintenance.Centripetal Bearings,High-Quality Bearings,Industrial Bearings,Explore our premium centripetal and radial ball bearings.
