Taper Locking Bushes are supplied as unmarked. We hold stock for various makes include Kobo, SKF, Challenge etc but offer a low price as we cannot guarantee which make will be supplied. All Taper Lock Bushes are new products. Tapered Locking Bushes: A simple device designed to permit easy positioning of pulleys, sprockets and other power transmission hubs and then fasten them securely in place to the shaft. Likewise, the removal process is simple, allowing for positional adjustments and periodic maintenance to take place easily. The standard material used to manufacture these tapered locking bushes is high-grade Cast Iron.
Installation.
1. Clean all parts of the bushing and bore of the hub thus removing any oil, lacquer or dirt, and clean the shaft of any rust or dirt. Install the tapered locking bush in the hub and match half holes to make complete holes (each complete hole will be threaded on one side only).
2. Oil the threads and either the end of the grub screws. Install screws loosely in holes that are threaded on the hub side.
3. Make sure that the bushing is free in the hub. Slip the assembly onto the shaft and align it in the desired position.
4. Tighten screws evenly and alternately until the part has tightened.
5. Using a hammer and a block, tap the large end of the bushing inwards around its perimeter. Re-tighten screws using the correct torque. Repeat this procedure until the screws no longer turn. Filling any remaining holes or cap screw heads with grease is a good practice to prevent dirt build-up.
Removal.
1. Remove all screws. Oil the threads and either the end of the grub screws.
2. Insert screws into the hole(s) that are threaded on the bushing side, for bushes with 2 screws there is 1 removal hole, for bushes with 3 screws there are 2 removal holes.
3. Tighten screws alternately until the bushing is loose in the hub. It may be necessary to tap on the hub to loosen the bushing. Once loose the hub will slide off the shaft.
Benefits: Simple installation and removal, cost-effective solution.
