Beam Coupling For Servo Motor, BCM Model beam flexible coupling bore: 3,4,5,6, 6.35 , 8,9, 9.525 ,10,11,12, 12.7 ,14,15,16.
1:Integrated sturcture,the ovrall use of high-strength aluminum alloy.
2:Flexible action to compensate radial,angular and axial misalignment.
3:Seamless shaft and sleeve connection,suitable for reversing.
4:Jack Screw type,Main use for Servo Motor.
