※The difference with this design is that the balance sdjustment screws tighten from the outer skirt at a radial angle.It is the optimal choice for spindles with restricted
   space.Balance adjustment screw holes can be fitted with screw-in plugs(optoin),eliminating high frequency noise and subsequent vibration.
※The data is not as good as it is available. Please contact CHENA for the remaining dimensions.
