⚙ Features & Advantages

✔ Combined Radial and Axial Load Support: The angular contact geometry allows the bearing to carry significant axial thrust in one direction in addition to heavy radial loads.

✔ High Precision Design: Manufactured by SKF, ensuring reliable performance, minimal vibration and low maintenance.

✔ High Axial Capacity: With a 40° contact angle, the axial load capacity is enhanced compared to standard angular contact bearings with smaller angles.

✔ Robust Dimensions: At 95×200×45 mm, this bearing offers substantial size and load-carrying capacity for heavy-duty applications.

✔ Versatile Use: Suitable for many industrial machines where shaft location in the axial direction is required and radial loads are high.

Specification / Ordering Notes

Confirm the exact variant suffix (e.g., “7319 B”, “7319 BECBM”, “7319 BECBY”) as cage type, seating variant or clearance grading may differ. Motion+1

Ensure the correct axial load direction is used (single-direction thrust load inherent in single-row angular contact bearings).

Check internal clearance and preload options—depending on mounting and operating conditions a paired set or duplex arrangement may be needed for bidirectional axial loads.

Ensure lubrication regime (grease or oil) is appropriate for speed, load and temperature conditions—bearing limiting speed is ~4–5 k rpm in typical configuration.
