Description

About SH Type QD Bushing

The SH QD bushing is the compact three-bolt member of the QD (quick-disconnect) family. A single split runs the full length of the taper bore, so the same bushing mounts conventionally with the flange outside the hub, or reversed with the flange inside it. It releases in minutes: loosen the three capscrews, thread them into the push-off holes in the flange, and the bushing walks itself out of the taper.


SH-QD bushing takes shafts from 1/2 in (12.7 mm) up to 1-3/8 in (34.9 mm) with a standard keyway, and it is the size most often found on small conveyors, fan and blower drives, pump drives, light agricultural machinery, and OEM sub-assemblies where a 2-11/16 in flange is all the space available.

SH vs SDS vs SK vs SF QD Bushing— which one fits

Work up the range only as far as the shaft and the load requires; a larger bushing needs a larger hub and a heavier flange.


• SH Bushing: 2-11/16 in flange, 3 × 1/4-20, 108 in-lb, 1.0 lb. The right choice for shafts up to 1-3/8 in with a standard keyway where space is tight.
• SDS Bushing: same 108 in-lb capscrew torque, but a 3-3/16 in flange and a 1-3/8 in body to take bores past 1-3/8 in.
• SK Bushing: 3-7/8 in flange, 3 × 5/16-18 at 180 in-lb, 2.0 lb, for medium-duty drives needing a stiffer flange.
• SF Bushing: 4-5/8 in flange, 3 × 3/8-16 at 360 in-lb, 3.0 lb, for heavier overhung loads.

Rule of thumb: if the shaft measures 1-3/8 in or less and the drive is light to medium duty, SH is the economical answer. If the shaft is bigger, or the component is heavy and overhung, step up to SDS or SK rather than boring an SH past its keyway limit.

Interchange with Martin, Dodge, Browning, and TB Wood's

SH is a letter designation shared across the industry, not a brand-specific part number. 

A CTS SH bushing matches the Martin SH, Dodge SH, Browning SH, and TB Wood's SH in taper, bolt circle (2-1/4 in), and capscrew pattern (3 × 1/4-20 × 1-3/8). 

Note that SDS, SD, SK, and SF are different types and are not interchangeable with SH: the flange, taper, and bolt circle all change.
