SKF 452319 M2/W502 SPHERICAL ROLLER BEARING

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

This SKF double-row self-aligning roller bearing is designed to withstand heavy loads while compensating for misalignment. Its brass cage provides the mechanical strength required for high speeds. This model is open, without seals, which facilitates maintenance while requiring clean operating conditions.

Features:
This self-aligning bearing incorporates two symmetrical rows of rollers that can support radial and axial loads in both directions. It is equipped with a solid brass cage that ensures good load distribution and excellent temperature resistance. Its cylindrical bore simplifies direct mounting on a shaft. The C4 internal radial clearance helps limit overheating and allows for higher rotational speeds. It features an annular groove and three lubrication holes on the outer ring, facilitating relubrication. The W502 tolerance on the outer diameter ensures increased operational precision by improving the bearing’s fit in the housing, thereby reducing the risk of misalignment and vibration.

Maintenance:
Periodic visual inspection helps detect signs of premature wear or the presence of contaminants. Regular lubrication is also essential to ensure the longevity of this bearing. This bearing can operate at temperatures up to 200 °C, but the actual temperature depends on the lubricant selected. Since it is not pre-lubricated, it is recommended to choose a high-performance lubricant suitable for your operating conditions. Before each relubrication, it is advisable to thoroughly clean the mounting area to prevent contamination. The presence of integrated lubrication channels allows for effective relubrication without disassembly.

Sealing:
This product is an open bearing with no integrated sealing system. This means it is not protected against dust, moisture, or solid particles. On the other hand, the absence of seals reduces rolling resistance and allows for easier visual inspection. The ability to relubricate regularly compensates for the lack of sealing by extending the bearing’s service life.
