13 www.jbj.co.uk/couplings.html #DriveLineHarmony “A” Type - Shrink Disc ® TRASCO ES Zero Backlash Jaw Couplings This type of coupling provides excellent kinetic uniformity. Furthermore, the absence of keys or set screws makes it a well-balanced coupling and greatly facilitates installation and removal. Exact radial/axial positioning is easy for those applications which require it. The absence of keyways also avoids fretting corrosion and backlash between the shaft and the hub. This is the ideal type of coupling for applications requiring precision and/or high rotational speeds. Approved according to ATEX Directive.
