SKF 6307 C4 Deep Groove Ball Bearing - 35x80x21mm - High Speed, High Temperature Industrial Motor Use
The SKF 6307 C4 Deep Groove Ball Bearing is engineered for demanding industrial environments requiring maximum operational reliability and speed capability. Featuring standard boundary dimensions of 35mm bore (d), 80mm outside diameter (D), and a 21mm width (B), this bearing utilizes the high-precision 63 series design. The critical C4 internal clearance (greater than standard C3) specifically accommodates thermal expansion, interference fits, and conditions where the inner ring operates significantly hotter than the outer ring. This design minimizes operational friction and prevents premature failure in applications like electric motors, high-speed pumps, and specialized industrial fans where heat buildup is a major concern.
Leverage SKF's patented steel purity and advanced rolling element geometry to significantly reduce vibration and noise output compared to standard alternatives. Optimized for high dynamic loads (Cr: 33.5 kN) and robust static stability (C0r: 19.0 kN), the 6307 C4 ensures extended service life and reduced maintenance cycles. Choosing SKF guarantees genuine quality, lower total cost of ownership, and proven performance in mission-critical machinery where downtime is costly. This bearing is the standard choice for reliable operation under elevated speed and thermal stress.
