Rulment cu role sferice SKF 22319 EK/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.

The spherical roller bearing is designed to accommodate high radial and bidirectional axial loads while compensating for misalignment. This SKF model features two symmetrical rows of rollers, an E-type design with a stamped steel cage, a 1:12 tapered bore, and an open design with an annular groove and three lubrication holes on the outer ring.

Features:
This SKF self-aligning bearing is designed to provide stable and long-lasting operation under severe mechanical conditions. Its internal architecture features two stamped steel window cages, a flangeless inner ring, and a floating guide ring, ensuring better roller retention, uniform load distribution, and reduced internal stresses during operation. The C3 internal radial clearance provides better tolerance to thermal expansion and promotes smooth rotation, even at high speeds. Thanks to its 1:12 tapered bore, installation is precise, reducing vibrations. It also features an annular groove with three lubrication holes on the outer ring, facilitating maintenance during operation.

Maintenance:
To ensure the longevity and performance of this double-row roller bearing, regular maintenance is essential. Its open design allows direct access to the internal components, facilitating visual inspection and cleaning. During maintenance, it is essential to remove any contaminants from the housing to prevent premature wear. Additionally, this model is not pre-lubricated, allowing the lubricant to be selected based on operating conditions. Relubrication must be performed at appropriate intervals and is facilitated by the annular groove and lubrication holes integrated into the outer ring, which ensure proper grease distribution and minimize the risk of contaminant buildup. Monitoring the operating temperature is also recommended to detect any abnormalities related to a lack of lubricant or contamination.

Sealing:
This SKF bearing is designed without an integrated sealing system. Its open design makes it more vulnerable to contaminants such as dust, water, or solid particles. This configuration therefore requires special attention to the environment in which it is installed. On the other hand, the absence of seals reduces internal friction and allows for higher rotational speeds.
