Product Overview: The 3313 Double-Row Angular Contact Ball Bearing
The 3313 bearing is a high-capacity component from our 3300 Series, designed to handle combined radial and axial loads in both directions. As a type of Angular Contact Ball Bearing, its double-row configuration is comparable to two single-row angular contact bearings arranged back-to-back, but with a more compact design. With dimensions of 65x140x58.7mm, this bearing provides exceptional rigidity and is ideal for applications requiring stiff shaft guidance.
Manufactured to precise industry standards, the 3313 ensures reliable performance and a long service life. Its ability to accommodate tilting moments makes it a superior choice for a wide range of industrial equipment where operational stability is critical. As a leading supplier of industrial components, we provide top-quality bearings like the 3313 to meet the demands of modern machinery.
