Ball screw spindle bearing
Main structures:
1. One-way thrust angular contact ball bearing: The contact Angle is 60°. This series can withstand a large axial load
  in a single direction and a certain radial load,
  so it needs to be used in pairs. It has high axial stiffness, high axial height, high acceleration capacity and low friction.
2. Both-way thrust angular contact ball bearing: The contact Angle is 60°. This series can bear both-way axial
  load and certain radial load, so it needs to be used in pairs.
  It has high axial rigidity, high axial height, high acceleration capacity and low friction.
  ZKLF and ZKLFA series have flanged mounting holes.

High speed electric spindle
special bearing
Features:
Can bear radial load and axial load in one direction, used in pairs.
High-speed electric spindle special bearings are used for contact angles of 15° (C), 18° (CE), 20° (D) and 25° (AC).
The smaller the contact Angle is, the higher the speed and radial bearing capacity are,
and the larger the contact Angle is, the greater the axial bearing capacity is.
