The 6311 C3 is a standard single row deep groove ball bearing, engineered for high speeds and capable of supporting both radial and axial loads. With a precise inner diameter of 55 mm, an outer diameter of 120 mm, and a width of 29 mm, this bearing features C3 radial internal clearance. This clearance is greater than normal, making it suitable for applications involving thermal expansion, misalignment, or where a looser fit is required. It is a fundamental component used across various industrial and agricultural machinery, ensuring reliable performance and efficient power transmission in demanding environments.
