air differential shaft

Description

GZ Air differential shaft
3''outer diameter:φ*5 Expand diameter:φ*8mm
1)Applicable tube ID:φ*6±0.2mm
2)Inside diameter(ID):φ*0mm
3)Standard width:*5mm
Can form central pressure type,pneumatic side compression type,mechanical side pressure type differential shaft.Center pneumatic friction torque mechanical properties loss small,according to the pressure to get accurate proportion to the size of the torque,realize tension from small to large,large range accuracy control.
