SKF BS2-2220-2RS5/VT143 SPHERICAL ROLLER BEARING

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 high-performance bearing from SKF is designed to ensure reliable operation even under extreme conditions. It is a self-aligning roller bearing, ideal for handling both heavy radial loads and axial forces in both directions. Its self-aligning capability makes it a suitable solution for misalignment and shaft deflection, which are common in industrial environments. This product stands out for its robustness, reinforced sealing, and excellent durability, even under severe conditions.

Features:
This self-aligning bearing features two rows of rollers, optimizing load distribution and providing remarkable operational stability. It is designed with a cylindrical bore that ensures precise and quick installation. The lightweight yet robust deep-drawn steel cage reduces inertia and improves rotation. The standard internal radial clearance ensures a good balance between stability and smooth operation, allowing for smooth rotation while limiting internal stresses during temperature fluctuations. This model is equipped with HNBR contact seals on both sides, providing excellent protection against external contamination. It is pre-filled with 25 to 45% SKF LGEP 2 grease, an extreme-pressure grease formulated with mineral oil and lithium soap. This lubricant is ideally suited for applications subject to heavy loads and performs effectively within a temperature range of -20 °C to 110 °C. Its NLGI 2 consistency ensures good adhesion, minimizes friction, and reduces wear. Finally, the presence of an annular groove and three lubrication holes in the outer ring facilitates maintenance and extends the bearing’s service life.

Maintenance:
This bearing is shipped pre-greased and should not be washed before installation. It can be relubricated as needed, particularly when the grease has reached the end of its service life. Relubrication should be performed slowly, preferably while the bearing is rotating, to distribute the lubricant evenly and avoid damaging the seals. It is recommended to use the same original grease (type LGEP 2). It is crucial to keep the lubrication areas clean during maintenance. Regular inspection of the grease level and bearing performance allows for early detection of any wear or deterioration. This product operates optimally within a temperature range of -20 °C to +110 °C.

Sealing:
The bearing is equipped with HNBR contact seals on both sides. This type of steel-reinforced seal provides an effective barrier against dust, moisture, liquid splashes, and other contaminants. HNBR (hydrogenated nitrile) ensures excellent resistance to heat, industrial oils, and chemicals. This sealing design ensures reliable operation, even in demanding environments. It also limits the ingress of contaminants, thereby reducing wear and extending the bearing’s service life. The only limitation is a slightly reduced maximum rotational speed due to the presence of the seals.
