Rulment cu role sferice SKF 22215 E/C4

Rulmenții cu bile pe role joacă un rol cheie în buna funcționare a instalațiilor supuse unor solicitări mecanice intense. Designul lor robust asigură o performanță fiabilă și continuă, chiar și atunci când condițiile de funcționare sunt instabile sau dificile.

This SKF spherical roller bearing features a C4 internal radial clearance, a unique design with two stamped steel window cages, a shoulderless inner ring, and a floating guide ring. Its ability to withstand heavy loads in both directions while compensating for misalignment makes it a reliable choice for users seeking robustness, smooth operation, and extended service life. The presence of an annular groove and three lubrication holes in the outer ring further ensures easy maintenance and long-lasting performance.

Features:
This double-row self-aligning roller bearing features an open design with a cylindrical bore, allowing for simple and precise mounting on the shaft. Its two pressed-steel cages reduce inertia, thereby improving the bearing’s responsiveness at high speeds and optimizing load distribution for smooth operation at high speeds. The C4 internal radial clearance is designed to accommodate significant thermal expansion, particularly in high-temperature environments or under heavy loads. It reduces internal stresses, facilitating smooth and stable rotation, even at high speeds. It also features an annular groove and three lubrication holes integrated into the outer ring, for easier maintenance. Its shoulder-free design allows for the use of a floating guide ring, which guides the rollers and contributes to stable operation even under varying loads.

Maintenance:
This open bearing requires regular relubrication to maintain its performance. It is important to use a lubricant suitable for the operating conditions, particularly in cases of high temperatures or heavy loads. The integrated lubrication system facilitates uniform grease distribution and the removal of particles. The absence of seals allows for quick visual inspection and direct access for cleaning. During each service, it is recommended to thoroughly clean the housings to prevent the ingress of contaminants. Adhering to these best practices ensures a longer bearing service life.

Sealing:
This model does not have built-in seals. It is therefore more exposed to dust, moisture, and other particles present in the environment. However, its open design has the advantage of simplifying maintenance and reducing internal friction. To maintain a clean environment, it is advisable to protect the surrounding areas during installation and to take immediate action in the event of contamination. Regular lubrication also helps minimize the risk of contamination and ensures reliable long-term operation.

Key Benefits:
- Withstands high radial and axial loads in both directions;
- Effectively compensates for misalignment and shaft deflection;
- C4 internal radial clearance adapted to thermal expansion, limiting internal stresses;
- Allows for direct relubrication thanks to the annular groove and lubrication holes;
- Operates at high speeds thanks to reduced inertia provided by the stamped steel cages;
- Withstands temperatures up to 200 °C with a suitable lubricant;
- Quick and easy installation thanks to the cylindrical bore.

Applications:
This type of bearing is particularly well-suited for industrial applications subject to heavy loads and variable operating conditions. It is found in conveyors, crushers, mining equipment, gearboxes, and material processing machines. It is also suitable for installations where mounting conditions do not allow for perfect alignment. Thanks to its robustness and adaptability, it is ideal for dusty or vibration-prone environments.
