FAQ

The 'C3' indicates that the bearing has a radial internal clearance that is greater than the standard 'Normal' clearance, which allows for thermal expansion at higher speeds or temperatures. The 'VT143' denotes that the bearing is factory-filled with a specific high-performance grease (ExxonMobil Polyrex EM), which is suitable for a wide temperature range.

Yes, the combination of C3 clearance and VT143 grease makes this bearing well-suited for applications with elevated operating temperatures, typically found in industrial fan systems.

The primary advantage is its ability to tolerate static and dynamic misalignment. The spherical outer ring raceway allows the inner ring and ball set to pivot, compensating for shaft deflection or errors in housing alignment without inducing excessive stress on the bearing.
