TAPER-LOCK ® WELD-ON HUBS
TAPER-LOCK ® BUSHING INSTALLATION AND REMOVAL
Special dimension hubs are available per your application requirements on a Made-To-Order basis. All stock U.S. Tsubaki hubs are made from 1045 steel bar stock. No powdered or sintered metal is used. The TAPER-LOCK ® weld-on hubs listed below include the appropriate tapered bores and mounting holes to mate with U.S. Tsubaki sprockets and other U.S. sprocket manufactures that conform to ANSI specifications.
U.S. Tsubaki offers the most complete line of TAPER-LOCK ® weld-on hubs for insertion and welding to produce “B” type sprockets, sheaves, and other applications without hub protrusion. To provide greater strength for this type of shaft locking mechanism and to reduce heat distortion caused by welding, these hubs are dimensionally interchangeable with our sprocket items.
TAPER-LOCK ® Bushing Installation
1 Clean and degrease the bore and tapered surface of the bushing and the tapered bore of the pulley/hub/sprocket. 2 Insert the bushing into the pulley/hub/sprocket bore and line up the holes (Half threaded holes must line up the half straight non-threaded holes). 3 Lightly oil the locking screws and insert but do not tighten yet. 4 When using a key, it should be fitted to the shaft keyway. There should be a top clearance between the key and the keyway in the mating bushing. 5 Clean and degrease the shaft. Fit pulley/hub/sprocket onto the shaft and locate in the desired position. 6 Using a hexagon socket wrench, gradually tighten the locking screws in accordance with the required tightening torque. 7 When the drive has been operating under load for a short period, approximately 30 to 60 minutes, stop the equipment and check that the screws remain at the required tightening torque. Adjust if necessary. 8 To avoid the ingress of dirt, fill all empty holes with grease.

TAPER-LOCK ® Bushing Removal
A Remove any loading to the equipment to enable a safe removal of components. B Slacken and remove all locking screws.
C Add lubricant to the previously removed screws and insert into jack-out hole/holes in the bushing. D Tighten the screws uniformly and alternately until the bushing is loose and the pulley/hub/sprocket can be moved freely on the shaft. E Remove the bushing/pulley/hub/sprocket assembly from the shaft.
