3306-BD-XL-2Z-C3 Angular Contact Ball Bearing 3306zz for Railways Double Row P5 Precision Rating

3306-BD-XL-2Z-C3 is a high-performance angular contact ball bearing engineered for heavy-duty industrial applications. It features a BD-type 40° contact angle, an XL (extra load) design that enhances radial and axial load-carrying capacity, double steel shields (2Z) for effective dust and debris protection, and a C3 radial internal clearance that accommodates thermal expansion in high-temperature or high-speed operating conditions. Its precision-machined raceways and high-quality balls ensure smooth rotation, low vibration, and long service life even under continuous high-load and high-speed operation.​
