Product Overview: The 5303 Double-Row Angular Contact Ball Bearing
The 5303 bearing is a high-performance component from our 5300 Series of Angular Contact Ball Bearings. With principal dimensions of 17x47x22.2mm, this bearing is engineered with two rows of balls in a back-to-back arrangement, enabling it to accommodate combined radial and axial loads in both directions. Its design provides a high degree of stiffness, making it an excellent choice for applications that require rigid support and precise shaft guidance.
As a leading supplier of industrial bearings, we ensure our 5303 bearings are manufactured from high-quality bearing steel to industry standards, guaranteeing reliability and long service life. The double-row configuration offers the functionality of two single-row angular contact bearings but within a more compact axial space, making it a space-efficient solution for various industrial machinery.
