SKF SEALED SPHERICAL BRG BS2-2215-2RS/VT143

Self-aligning 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 spherical roller bearing stands out for its self-aligning capability and robustness. Its two rows of rollers allow it to withstand very high loads by distributing them evenly, and its pressed steel cage ensures good roller stability and helps maintain performance over time. This model is pre-lubricated and sealed with two NBR seals.

Features:
Designed to withstand both high radial loads and axial loads in both directions, this self-aligning bearing naturally accommodates misalignment. Its cylindrical bore facilitates direct mounting on a shaft without additional accessories. Its deep-drawn steel cage minimizes inertial effects while ensuring even force distribution. The product features an annular groove and three lubrication holes, ensuring easy maintenance. It is pre-lubricated and filled with 25 to 45% SKF LGEP 2 grease, a special lithium soap-based lubricant compatible with a wide temperature range. Thanks to its contact seals on both sides, this sealed model is ideally suited for applications where the environment is exposed to dust or moisture. Due to the contact between the seals and the rings, the permissible rotational speed is lower than that of an open bearing, but remains sufficient for applications at moderate speeds.

Maintenance:
This bearing is delivered pre-greased and ready for use. The presence of an annular groove and three holes in the outer ring facilitates relubrication when the grease reaches the end of its service life. This operation must be performed slowly, preferably while the bearing is rotating, to ensure proper distribution without damaging the seals. It is recommended to use the same grease as the original to avoid any incompatibility. Regular inspection of the lubrication level and the bearing’s overall condition helps anticipate potential damage. When servicing the bearing, it is essential to ensure the cleanliness of the lubrication points to prevent contamination. The product is suitable for operating temperatures up to 90 °C, with a temporary tolerance up to 120 °C.

Sealing:
This model is equipped with NBR lip seals on both sides. These seals, reinforced with a steel cage, provide an effective barrier against contaminants, water, and liquid splashes. Nitrile butadiene (NBR) offers good resistance to industrial oils, grease, and moderate temperatures. This sealing solution protects the bearing without compromising its durability, but it slightly limits the permissible rotational speed compared to an open bearing. The assembly ensures reliable operation in dusty or humid environments.

Brand information:
SKF (Svenska Kullager-Fabriken) is a Swedish multinational group founded in 1907 and a world leader in the field of mechanical bearings. SKF is one of the world’s leading suppliers of bearings, seals, mechatronic components, lubrication systems, and services designed to improve the reliability of rotating equipment and ensure its performance.
