Product Overview: The 7318 Angular Contact Ball Bearing
The 7318 bearing is a high-precision, single-row angular contact ball bearing designed to accommodate combined radial and axial loads simultaneously. With its principal dimensions of 90mm Bore Diameter, 190mm Outer Diameter, and 43mm Thickness, this component is a key part of our 7300 Series. These bearings are engineered with a specific contact angle, typically 40 degrees, which allows them to sustain significant axial loads in one direction. For applications requiring support for axial loads in both directions, these bearings are often mounted in pairs (back-to-back, face-to-face, or in tandem).
As a specialist in industrial mechanical parts, we ensure our 7318 bearings meet stringent quality standards, delivering superior performance in high-speed and high-precision applications. Their robust design and construction make them indispensable in demanding machinery.
