FAQ
Q1: What is the main difference between angular contact and deep groove ball bearings?
A: Angular contact bearings are designed to handle combined loads, especially axial loads, while deep groove ball bearings mainly support radial loads.
Q2: Can 7205 bearings be used in pairs?
A: Yes, they are often mounted in pairs (back-to-back or face-to-face) to support axial loads in both directions.
Q3: Do you offer ceramic or high-precision versions?
A: Yes, we offer ceramic and precision-grade versions such as P5 and P4 for high-speed applications.
