Q: Are 399A and 394A two separate complete bearings?
A: No. 399A is cone, 394A is cup. They must be paired as one complete bearing set.
Q: Can single 399A/394A bear bidirectional axial load?
A: Single set only withstands one‑way axial load. Two sets are required for bidirectional support.
Q: Can cone and cup be replaced separately?
A: Original matched cone‑cup pair is recommended to guarantee service life.
Q: Is preload adjustment required on installation?
A: Yes, correct preload setting is essential during mounting work.
