Product Overview: The 7019 Angular Contact Ball Bearing
The 7019 bearing is a high-precision, single-row Angular Contact Ball Bearing designed for applications that require high speed and accuracy. Part of our versatile 7000 Series, this bearing is engineered to accommodate combined loads, meaning it can handle both radial and axial forces simultaneously. Its specific design, featuring a 40° contact angle, provides high axial load capacity in one direction, making it essential for rigid and precise shaft guidance. For optimal performance, these bearings are typically mounted in pairs (back-to-back, face-to-face, or in tandem) to manage axial loads in both directions and provide a stiff bearing arrangement.
With industry-standard dimensions of 95mm Bore Diameter, 145mm Outer Diameter, and 24mm Thickness, the 7019 is a reliable choice for a wide range of demanding industrial machinery. Our commitment is to supply high-quality components that ensure longevity and operational excellence.
