Bush Description
The BTL 3535 is a standard Taper Lock bush intended for fastening pulleys, wheels, shaft couplings and other components to shafts. It is produced from grey cast iron.
Taper Lock bushes have a conical outer surface and a cylindrical inner bore with H7 tolerance including a standardized keyway (for technological reasons, some sizes with a reduced keyway). Once fixed, the component is capable of transmitting torque while being secured against axial displacement.
Typical Applications
The BTL 3535 Taper Lock bushes are used in a variety of industrial applications.
They are used to fix standard and non-standard V-belt, timing and flat pulleys, sprockets, TB hubs, shaft couplings and other components.
Materials

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.
Information: The tapered locking bushing size is defined by 4 digits representing two numbers. The first two digits represent the maximum bore size and the second two digits represent the bushing length. For example, product number 1008 has a max. bore of 1.0 inches and a total length of 0.8 inchesInstallation.
