SKF HRA+ SPHR ROLLER BRG 24130 CC/W33

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.

This SKF spherical roller bearing is designed to withstand heavy radial and axial loads while ensuring smooth and stable operation. Thanks to its self-aligning capability and robust construction, it effectively compensates for misalignment or shaft deflection. This model is particularly valued for its reliability in systems subjected to dynamic loads and high rotational speeds.

Features:
This double-row roller bearing is equipped with two windowed cages made of stamped sheet steel, a shoulderless inner ring, and a floating guide ring centered on the inner ring. Its cylindrical bore allows for direct mounting on the shaft, simplifying installation. Thanks to its lightweight and durable cages, this component ensures even distribution of radial and axial loads in both directions. The standard internal radial clearance promotes balanced mechanical response, even at high speeds. Its open design, which lacks seals, reduces rolling resistance, thereby improving overall efficiency and enabling high rotational speeds while minimizing the risk of overheating.

Maintenance:
Regular maintenance helps maintain performance and extend the product’s service life. Its open design requires closer monitoring of operating conditions. The presence of an annular groove and three lubrication holes facilitates relubrication, which must be performed at appropriate intervals, particularly in dusty or humid environments. The choice of lubricant is important, especially at high temperatures. This model can operate up to 200 °C, provided a specific lubricant is used. To ensure stability, a tight fit on the shaft is recommended.

Sealing:
This model has no built-in seals. Its open design improves ease of inspection and maintenance but makes it more vulnerable to contaminants. Dust, solid particles, and moisture can compromise performance if not properly managed. However, its annular groove and three holes in the outer ring facilitate the removal of contaminants.

Present in more than 130 countries, the brand is distinguished by its innovation, reliability, and commitment to sustainable performance. SKF serves approximately 40 industrial sectors worldwide.

Key Benefits:
- Simultaneously supports heavy radial and axial loads in both directions;
- Compensates for misalignment and shaft deflection without loss of performance;
- Lightweight deep-drawn steel cages suitable for high rotational speeds;
- Open design allowing for easy inspection and maintenance;
- Integrated lubrication system with an annular groove and three lubrication holes;
- Suitable for operating temperatures up to 200 °C with the appropriate lubricant.

Applications:
This self-aligning bearing is used in many industrial applications where loads are high and speeds vary. It is suitable for conveyors, crushers, industrial fans, heavy-duty pumps, steelmaking equipment, and agricultural machinery. Its design makes it ideal for fixed mountings and environments where perfect shaft alignment cannot be guaranteed. It also offers a reliable solution in installations subject to demanding thermal conditions or high dynamic loads.
