■Features
(1) With pilot on flange of the inner diameter, the tightening lock screw presses hub inner diameter. This generates effect to control instability on the hub end face and outer diameter (centering effect).
(2) Free phase adjustment and positioning.
(3) No hub movement in axial direction when tightened with lock screw.
(4) No backlash after tightening.
■Recommended Tolerance of Shaft and Hub
Shaft Outer Diameterh7 (g6)
Hub Inner DiameterH7
Finish surface roughness at or below 1.6a in shaft and 3.2a in hub.
