Can Samsung bearings be used without springs?

Samsung bearings can't be used without springs. Because there is a spring in the ball cage, the spring head has a smooth pad and leans against the Samsung bearing. The function of the spring is to apply axial pre-tightening force to the axial clearance of the bearing. Without this spring, the spindle will swing when it rotates at high speed, which has great influence on the spindle itself and machining quality.
