Detail Information
About QD Weld On Hub
CTS® QD Weld On Hubs
The H-SH weld-on hub turns a plate-steel sprocket, pulley disc, or fan wheel into a QD-mounted component. It is a short carbon-steel hub, taper-bored and drilled to the SH pattern — 3 in outside diameter, 2-1/4 in bolt circle, three 1/4-20 capscrew holes — with a plain outside surface that you weld to the plate. Once the hub is welded and the plate is finished, any standard SH QD bushing drops in and locks the assembly to the shaft.

Assembly: hub with SH QD bushing
1. Slide the SH bushing into the welded hub with the keyway aligned to the shaft key.
2. Line up the three capscrew holes with the tapped holes in the hub.
3. Fit three 1/4-20 × 1-3/8 capscrews with lockwashers.
4. Tighten in rotation in two or three stages to 108 in-lb (12.2 N·m).
5. Check runout on the finished component and re-torque after the first hours of running.
To remove, back the capscrews out and thread them into the push-off holes in the bushing flange; the bushing walks out of the taper, and the component comes off the shaft without a puller.
