SKF 229750 J/C3R505 SPHERICAL ROLLER BEARING

Self-aligning roller bearings play a key role in the proper functioning of equipment subjected to high mechanical loads. Their robust design ensures reliable and continuous performance, even under unstable or demanding operating conditions.

Designed to withstand high loads and accommodate misalignment, this spherical roller bearing is specifically engineered for railway axle boxes. Thanks to its double row of rollers and self-aligning capability, it ensures smooth and reliable transmission of mechanical forces. This open, seal-less model features a stamped steel cage guided by the inner ring and a C3 radial clearance.

Features
This self-aligning bearing features a cylindrical bore for quick and easy mounting on a machined shaft. Its deep-drawn steel sheet cage, guided by the inner ring, reduces inertia, thereby optimizing the bearing’s performance at high speeds while ensuring good mechanical strength. Its C3 internal radial clearance also promotes stable high-speed rotation by giving the bearing excellent tolerance to temperature variations. Finally, its robust structure allows it to withstand high radial and axial loads in both directions while compensating for misalignments and shaft deflection.

Maintenance:
It is recommended to regularly check the lubricant level, particularly in dusty or humid environments. The open design facilitates access for visual inspections, cleaning, or relubrication. All maintenance must be performed in a clean environment to prevent contamination. Special attention should be paid to signs of wear, such as increased noise or temperature.

Sealing:
This product is designed without seals, which allows for higher rotational speeds and reduces internal friction. However, this results in increased vulnerability to external elements. The absence of a barrier against dust or moisture requires adequate environmental protection. This design choice offers the advantage of simplified maintenance but requires increased vigilance.

Brand Information:
SKF, founded in 1907, is a major player in the field of solutions for rotating equipment. Specializing in bearings, seals, and lubrication systems, the Swedish brand is recognized for its technical expertise and innovations that meet the diverse needs of industrial sectors such as automotive, aerospace, energy, and food processing.

Key Benefits:
- Self-aligning capability to compensate for misalignment and shaft deflection;
- Open design allowing for visual inspection and easy maintenance;
- C3 radial clearance ensuring good tolerance to thermal expansion;
- Deep-drawn steel cage for high mechanical strength and reduced inertia;
- Reliable high-speed operation thanks to low internal friction.

Applications:
This double-row roller bearing is ideally suited for railway axle boxes, where it withstands heavy loads while compensating for misalignments caused by dynamic rail stresses, such as vibrations, repeated shocks, and load variations. Its robustness and self-aligning capability make it the preferred choice for ensuring the reliability and safety of rolling stock, even under demanding operating conditions.
