The SKF 3306A-2Z/C3MT33 is a high-quality double row angular contact ball bearing, designed for applications requiring high rigidity and the ability to accommodate combined radial and axial loads. This bearing features two Z-shields (non-contacting shields) on both sides, providing protection against contaminants while retaining lubricant. It has a C3 internal clearance, which is greater than normal, suitable for applications with temperature differences or where shaft expansion is expected. The MT33 designation indicates a specific cage design or material, often related to optimized performance. With a bore diameter of 30 mm, an outer diameter of 72 mm, and a width of 30.2 mm, this genuine SKF bearing ensures reliable and efficient operation in demanding industrial and agricultural machinery.
