What the AI looks for in Automotive Performance Clutch Release Bearings

Bearing type: Match the design: a mechanical bearing on a fork or sleeve, or a concentric slave cylinder (hydraulic release bearing). These are different systems and cannot be substituted without conversion parts.
Contact face: The bearing face diameter and profile must suit the pressure plate's diaphragm fingers. A mismatched face causes noise, finger wear and incomplete release.
Air gap and travel: On hydraulic or aftermarket bearings, set the installed clearance to the manufacturer's specified range using shims or measurement. Too little gap preloads and destroys the bearing. Too much leaves the clutch dragging.
Replace with the clutch: Always fit a new release bearing (and pilot bearing) whenever the clutch is replaced. A failed bearing means removing the transmission again.

Reusing the old bearing during a clutch job.
Installing a hydraulic release bearing without measuring and setting the air gap.
Cheap unbranded concentric slaves, which often leak early.
