Bearing roller cylindrical

Cylindrical roller bearings are a type of bearing that uses cylindrical rollers to provide movement between the inner and outer rings. They are capable of withstanding high radial loads and are used in a variety of industries that require high load capacity.

Types of cylindrical roller bearings

- single row (the most common type of bearing, in which one row of rollers interacts with the grooves on the inner and outer rings; can withstand radial loads, but have limited ability to withstand axial loads);
- double-row (have two rows of rollers, which provides greater load capacity (both radial and axial), they are used in conditions where increased load capacity is required or with large dimensions);
- with end stops (have additional end stops so that the rollers do not fall out of the working area at high speeds);
- with guides (bearings with built-in guides that ensure precise positioning of the rollers and minimize their oscillations, which is especially important at high speeds).

Advantages of cylindrical roller bearings

- high capacity for radial loads (due to the cylindrical shape of the rollers, the bearings can withstand significant loads);
- minimal friction (compared to ball bearings, cylindrical rollers have a larger contact area, which reduces friction);
- high stability and accuracy (due to their design, they provide more uniform movement).

Rollers are usually made of high-quality carbon steel or special steels with increased wear resistance.
The spacers can be made of metal, nylon, polyamide, or other materials that reduce friction and wear.

Designation options for cylindrical roller bearings according to international standards

NU, N, NJ, NF, NUP - different types of cylindrical roller bearings.
NU - with a split sleeve that allows axial movement of the outer ring.
N - without axial movement restriction, suitable for use on one side.
NF - one flanged outer ring to limit the axial movement of one of the rings.
NJ - with one flange for axial movement.
NUP - with flanges for axial movement of both rings.

For example - NU 205 E
NU - bearing type.
205 - size.
E - bearing with increased strength characteristics.

Cylindrical roller bearings are widely used due to their ability to withstand high radial loads and efficiency at high speeds

- automotive industry (gearboxes, vehicle wheels, transmission and suspension mechanisms)
- metallurgical and mining industry (conveyors, blast furnaces, crushers, various types of presses, mining equipment, bulldozers and excavators)
- energy (generators, turbines, hydroelectric power plants);
- metalworking and machine building (machine tools, high-precision mechanisms);
- Robotics and automation (robotic systems, conveyors);
- transportation and rail transport (train wheels, heavy-duty vehicles, trucks, buses and other vehicles)
- automotive and aircraft engines (internal combustion engines);
- High-speed technologies (high-speed machines and devices: centrifuges, electric generators and turbochargers);
- Agriculture (tractors, combines);
- aviation and astronautics (turbine and compressor mechanisms).
