• Q1: What does DB matching stand for?

  DB means back-to-back paired arrangement, bearing larger overturning moment and bidirectional axial load.

• Q2: What is ATY cage material?

  ATY is glass fiber reinforced nylon cage, lightweight, low friction and fit high-speed working conditions.

• Q3: Can you upgrade precision to P4?

  Yes, 7001ATYNDBMP4 ultra-precision matched bearing can be customized for ultra-high accuracy equipment.
