A convenient means to secure fan rotors, metal pulleys, plate sprockets, impellers etc to a shaft
Welding not necessary
For use with parallel bore eliminating the price of drilling, tapping and taper boring
Keyed version also designed for heavy duty applications
Installing a Taper Lock bush, including Martin or Fenner Taper Lock bush elements, is as follows:
Screws should be tightened alternately and evenly until all screws are pulled up and the bushing is square into the hub.
The Taper Lock bush needs to be thoroughly cleaned, removing all traces of oil, grease, dirt, and metal filings. Clean the shaft, the bore, the exterior of the bushing, and the bore of the hub where the bush is to be installed into, ensuring the bush is taken off the hub, should it already be installed.
Examine the bushing to make sure all surfaces are free from nicks and burrs, and ensure the bushing does not have any indications of cracking or exhaustion. Place the bushing in to the hub and match fifty percent holes to make finish holes. It is important to note that the holes need to be matched, not really the threads. Each hole will be threaded on one side only.
Oil threads, the idea of the arranged screws or threads, and beneath the head of the cap screws. After that place the screws loosely into the holes that are threaded on the hub-side
Ensure that the Taper Lock bush is free of charge in the hub, then slide the assembly onto the shaft and locate in the required position. Insert the correctly sized key in to the shaft keyway, making sure the key is a press fit into the shaft keyway. Ensure there can be an air gap between the top of the key and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Make sure that there is no oil or lubricant between the taper externally of the bushing and the taper bore of the hub, to which the bushing has been installed.
Screws should be tightened alternately and evenly until all screws are pulled up and the bushing is square into the hub.
Utilizing a hammer and block, or sleeve, against the huge end of the Taper Lock bush will avoid harm to the bushing. Gently tap against the busing to ensure it really is seated squarely. The screws are then tightened additional. A torque wrench can be used to tighten the screws alternatively and evenly until they are all to the suggested torque setting.
Repeat this alternate hammering and screw tightening before specified torque is achieved no longer requires tightening following hammering. IMPORTANT: After a period of running under normal conditions, it is suggested that the application form be reviewed to ensure the torque settings of the screws are accurate, and don’t need re-tightening.
Fill the holes that aren’t used in combination with grease or silicone sealant to avoid them from filling with dirt and/or rust.
Removal of a Taper Lock bush, including Martin or Fenner Taper Lock bush elements, is as follows:

Remove all screws, essential oil threads, and the point of the set screws or threads, under the head of the cap screws.
Insert screws in to the holes that are threaded upon the bushing side, because shown in Physique 2. In sizes where washers are found under the screw head, make sure to make use of these washers. Please note that there should always end up being one screw left that’s not used when removing the bushing.
Tighten the screws alternately before bushing is loosened in the hub. If the bushing will not loosen immediately, tap on the hub to assist remove.
When installing or removing a Taper Lock bush, it really is imperative that simply no lubrication be used between the taper. The existence of lubricant on the tapered surfaces is not attractive, as the taper bushing relies on friction to operate successfully, and lubricants reduce friction. use industry standard Part Numbers to identify the specifications of every Taper Lock bush or Taper bush.
