7. FAQ

Q1: What does ATR stand for in 7902ATR?

A means 30° contact angle; T means phenolic resin cage; R is internal design suffix.

Q2: Can 7902ATR work alone for bidirectional axial load?

No. Single angular contact bearing only takes one‑way axial load. It needs to be paired (DB/DF/DT) for bidirectional axial force.

Q3: Do you support OEM private logo?

Yes, private logo printing is supported, certain MOQ required.

Q4: What is your warranty term?

12‑month warranty against manufacturing defects, excluding man‑made damage and improper installation.
