ES backlash coupling
“A” type - shrink disc execution
This type of coupling provides excellent kinetic uniformity. Furthermore, the absence of keys or grubscrews makes ita very
well balanced coupling and graetly facilitates installation and removal.
An exact axial and radial positioning is very easy. The absence of keyways also avoids fretting corrosion and backlash
between the shaft and the hub. This ist the ideal type of coupling for applications requiring precision and / or high
rotational speeds.
