Double Row Full Complement Cylindrical Roller Bearings

Double Row Full Complement Cylindrical Roller Bearings

Double row full complement cylindrical roller bearings are a type of rolling element bearing designed to handle high radial loads by incorporating two rows of cylindrical rollers without a cage or separator. The absence of a cage allows for maximum roller density, resulting in increased load-carrying capacity.

Features

Double Row Design

These bearings have two rows of cylindrical rollers, providing higher radial load-carrying capacity compared to single-row designs.

Full Complement of Rollers

Similar to single-row full complement bearings, these bearings lack a cage, allowing for a complete set of cylindrical rollers in each row.

Increased Radial Load Capacity

The double row configuration enhances the radial load-carrying capacity, making these bearings suitable for applications with heavy radial loads.

Axial Load Capacity

While primarily designed for radial loads, double row full complement cylindrical roller bearings can also accommodate certain axial loads. However, their axial load capacity is generally lower compared to their radial load capacity.

Enhanced Rigidity

The absence of a cage increases the rigidity of the bearing, which can be beneficial in applications where rigidity is crucial.

Applications

These bearings find applications in heavy-duty machinery and equipment, including but not limited to rolling mills, gearboxes, and other industries where high radial loads and rigidity are essential.

Alignment

Like single-row full complement bearings, double row designs may have slightly less ability to accommodate misalignment compared to bearings with cages.

Operating Temperatures

The operating temperature of these bearings can vary depending on the materials used and the specific design.

Lubrication

Proper lubrication is crucial for reducing friction and preventing premature wear. Lubrication requirements may vary based on the specific design and operating conditions.

Precision and Tolerance:

Bearings are manufactured with specific tolerances to ensure proper fit and alignment. Precision levels such as P0, P6, or P5 indicate the level of manufacturing precision.
