Rulment cu role sferice SKF 22215 E/C3

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.

Spherical roller bearings are designed to withstand very high loads while providing effective self-alignment. They are distinguished by their ability to compensate for misalignment and shaft deflection, even under severe conditions. This SKF model, of the E-type design, is an open bearing featuring a windowed cage made of stamped sheet steel, an internal radial clearance of C3, and an annular groove with three lubrication holes on the outer ring.

Features:
This double-row roller bearing is designed to simultaneously handle radial and axial loads in both directions. Its E design includes two stamped steel window cages, a shoulderless inner ring, and a floating guide ring. This configuration optimizes load distribution, minimizes internal friction, and improves stability at high speeds. Its enlarged radial clearance (C3) allows for the absorption of thermal expansion while maintaining rotational stability. The cylindrical bore simplifies direct mounting on the shaft. This bearing is designed for high speeds, thanks to its lightweight cage and the absence of seals, which reduces internal friction. Its annular groove and the three holes on the outer ring ensure effective lubrication.

Maintenance:
Regular relubrication is essential to maintain this bearing’s performance, and its open design facilitates visual inspections. Since this bearing is not pre-lubricated, it is essential to select a lubricant suitable for high loads and operating temperatures. In the event of exposure to contaminants or visible wear, the housing and mounting area must be thoroughly cleaned before relubrication. It is recommended to maintain a clean environment around the bearing to minimize the ingress of particles. The product can operate at temperatures up to 200 °C, provided the lubricant is compatible with this temperature range.

Sealing:
This bearing does not have an integrated sealing system. Its open design makes it susceptible to moisture and dust. However, the presence of an annular groove and three lubrication ports allows for targeted relubrication, which helps remove internal contaminants. This type of configuration requires increased vigilance regarding operating conditions, particularly in dirty or humid environments. Regular maintenance is essential to maintain performance and extend the product’s service life.
