Bearing components are essential for the proper functioning of industrial machines. Their role is to guide movements while reducing friction. Among the various models available, cylindrical roller bearings provide high precision and an extended lifespan. They are characterised by a high level of radial load capacity and the ability to operate at high speeds.

Suitable for the most demanding environments, they cater to every type of application. Rubix offers a comprehensive range of cylindrical roller bearings that combine robustness and reliability.

Manufactured from steel, polyamide, or brass, cylindrical roller bearings ensure linear contact for optimal radial support. They consist of three essential components, starting with the rollers themselves. An inner and outer ring provide proper retention. Finally, the roller cage helps guide the rollers.

With a rigid design, these bearings can withstand high radial loads while limiting axial movement. This robust shape reduces friction and enhances precision. These are crucial advantages for the execution of the most demanding industrial applications.

In standard or specific series, the nomenclature indicates the level of play, size, and design in accordance with standards.

They differ from tapered roller bearings, which can support both axial and radial loads. On the other hand, ball bearings favour precision in smaller machines. Needle bearings are characterised by their compact size but have lower load capacities.

Cylindrical roller bearings are used in numerous industries. They can be found in various machines within automated production lines, pumps, gearboxes, and motors.

• Transmissions in the automotive industry;
• Turbines, alternators, and wind turbines for energy production;
• Suspension and propulsion systems in the railway industry;
• Heavy-load motors and rolling mills for steel and metallurgy;
• Machines in the paper industry;
• Presses and tools in mechanical engineering;
• Production lines and conveyor systems in the food industry;
• Screens, grinders, crushers, and other machines in the mining and construction industries.

Cylindrical roller bearings excel in environments subjected to high speeds. Their reliability and robust design adapt to various HSE constraints for perfect operational safety.

Cylindrical roller bearings come in several models to meet the various mechanical constraints of industrial installations.

• Single-row systems are suitable for applications where radial load predominates. They stand out for their excellent rigidity.
• The double-row bearing is ideal for significant constraints, allowing for better load distribution.
• By increasing load capacity, multi-row bearings are offered for the heaviest systems.
• Depending on the needs, some bearings incorporate shoulders or a stop for better management of axial forces.

Cylindrical roller bearings can be installed quickly with separable rings. Even in hard-to-reach locations, they are designed for simplified installation. Special attention should be given to lubrication with greases suitable for temperature and speed. Preventive measures are recommended through regular checks of play, vibrations, alignment, and the edge of the rings.

The main criteria are load level, speed, temperature, and type of environment. It is essential to determine the internal clearance (C3 or CN) and the dimensions of the bearings. The presence of a fixed or free support is also crucial.

The choice of cage also plays an important role:

• Brass is ideal for high temperatures;
• Polyamide promotes quiet operation;
• Steel is intended for standard conditions due to its reliability;
• In a dusty environment, a sealed cage bearing is recommended.

• The FAG & INA brands from the Schaeffler group are distinguished by their high precision. They offer standard and special series for technical applications.
• The NTN & SNR brands provide products with proven robustness featuring double rows for heavy loads.
• SKF bearings are synonymous with consistency, offering a wide choice in NU, NJ, and NUP.
• The NSK brand and its patented cages provide low noise and low friction performance.
