FAQ

The 'UA' suffix indicates a universal design for matching. This means the bearing has specific clearance/preload characteristics that allow it to be mounted in pairs (back-to-back, face-to-face, or tandem) without needing special shims or adjustments, ensuring proper load distribution.

The FAG 7405-B-MP-UA with its solid brass cage ('MP') is generally suitable for operating temperatures up to 120 deg C. For applications exceeding this, consult the manufacturer's datasheet for potential limitations or requirements for special lubrication.

While angular contact ball bearings are designed to accommodate combined (axial and radial) loads, they must always be subjected to an axial load to function correctly. They cannot be used for purely radial loads, as this would lead to improper ball-raceway contact and premature failure. They are typically used in pairs to handle radial loads and axial loads in both directions.
