Trantorque GT Series 1” Keyless Bushings provide a zero-backlash frictional connection that will never wear or pound out and can accommodate high-torque, thrust, bending, and/or radial loads. Designed with an external counter torque nut for easier installation, by allowing the system to be held from rotating during installation. Trantorque GTR keyless bushing is the ideal solution for high power or critical timing applications.
It offers a mechanical shrink-fit eliminating the problems of fretting corrosion, backlash and key wallowing. Locks and unlocks with the twist of just one nut. Precise radial and axial adjustment on shaft. Ideal for timing components. Dec 26, After several blows try to loosen the nut some more then repeat, and bushpruning.buzz the bushing lets go.
Note you can spray WD into the bushing; but; you need to make sure the bushing is clean and all the WD removed before re-using the bushing. Also known as Trantorque bushings, these tighten with a twist of the collar nut- no screws needed.
As you tighten the collar nut, the inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.
Stainless steel bushings are corrosion resistant for use in harsh environments. For technical drawings and 3-D models, click on a part number. Trantorque QC–simply a better tapered bushing! U.S. Patent #5, and 6, Other patents pending. Trantorque QC Keyless Bushings are recommended for use in synchronous belt sprockets bored for QD bushings. Consult Fenner Drives for applications incorporating other components bored for QD bushings.
Depending on the pulley–bushing combination and customer preference the bushing may be recessed in the pulley for a compact assembly. While shafts without keyways are stronger, keyless bushings can also be used with keyed shafts by positioning the inner ring slit opposite keyway and a locking screw over the keyway.
OK to use with keyed shaft. To Remove TAPER-LOCK Type Bushings 1. Loosen and remove all mounting bolts. 2. Insert bolts into all jack screw holes indicated by dark removal holes in Figure 1 on page 1.
3. Loosen the bushing by alternately tightening the bolts in small but equal increments until the tapered sprocket/sheave and bushing surfaces disengage.
