It is the most successful shaft fixing on the market place today with a full range of both metric and imperial sizes in addition to a full range of weld-on hubs, bolt-on hubs and hub adaptors.
Ease of installation and removal
Equivalent to a shrink-on fit upon uniform load applications and therefore eliminating the price of a key

Standard range fits up to 125mm/5″ shafts
Particular 4-hole feature for balanced assemblies
Complete short reach range offered, for compact lightweight assemblies
High grade, close grain iron (GG25) material
Spherodial Graphite (S.G.) iron construction on some sizes to give increase maximum bores
Manufactured from steel to provide convenient methods to secure fan rotors, steel pulleys, plate sprockets, impellers etc. to a shaft.
Shouldered outer diameter permits easy location
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 components, is as follows:
Screws should be tightened alternately and evenly until all screws are pulled up and the bushing is sq . into the hub.
The Taper Lock bush must 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 in which the bush is usually to be installed into, making sure the bush is removed from the hub, should it already be installed.
Verify the bushing to ensure all surfaces are clear of nicks and burrs, and guarantee the bushing has no indicators of cracking or fatigue. Place the bushing into the hub and match half holes to make comprehensive holes. It is important to notice that the holes need to be matched, not really the threads. Each hole will be threaded on one side only.
Oil threads, the point of the set screws or threads, and beneath the head of the cap screws. After that place the screws loosely in to the holes that are threaded on the hub-side
Ensure that the Taper Lock bush is free in the hub, after that slip the assembly onto the shaft and locate in the desired position. Insert the properly sized key in to the shaft keyway, ensuring the key is a press fit into the shaft keyway. Ensure there can be an air gap between the top of the essential and the bushing keyway slot. This will prevent cracking of the bush. IMPORTANT: Ensure that there is no oil or lubricant between your taper on the outside of the bushing and the taper bore of the hub, to which the bushing is being installed.
Screws ought to be tightened alternately and evenly until all screws are pulled up and the bushing is square into the hub.
Using a hammer and block, or sleeve, against the huge end of the Taper Lock bush will avoid harm to the bushing. Lightly tap against the busing to make sure it really is seated squarely. The screws are after that tightened further. A torque wrench is used to tighten the screws on the other hand and evenly until all of them are to the suggested torque setting.
Repeat this alternate hammering and screw tightening until the specified torque is achieved no longer requires tightening following hammering. IMPORTANT: After a period of running under normal conditions, it’s advocated that the application be reviewed to ensure the torque configurations of the screws are accurate, and don’t need re-tightening.
Fill up 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 parts, is as follows:

Remove all screws, oil threads, and the idea of the set screws or threads, beneath the mind of the cap screws.
Insert screws into the holes that are threaded on the bushing side, since shown in Figure 2. In sizes where washers are found under the screw head, be sure to make use of these washers. Please be aware that there should end up being one screw left over that is not used when eliminating the bushing.
Tighten the screws alternately before bushing is loosened in the hub. If the bushing does not loosen instantly, tap on the hub to aid 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 appealing, as the taper bushing relies on friction to operate effectively, and lubricants decrease friction. use industry standard Component Numbers to identify the specifications of every Taper Lock bush or Taper bush.
