It’s the most successful shaft fixing on the market place today with a complete selection of both metric and imperial sizes in addition to a full selection of weld-on hubs, bolt-on hubs and hub adaptors.
Ease of installation and removal
Equal to a shrink-on fit on uniform load applications and therefore eliminating the expense of a key
No costly reboring: complete range of both metric and imperial available
Standard range fits up to 125mm/5″ shafts
Special 4-hole feature for balanced assemblies
Complete short reach range obtainable, for compact lightweight assemblies
High grade, close grain iron (GG25) material
Spherodial Graphite (S.G.) iron structure on some sizes to give increase maximum bores
Manufactured from metal to provide convenient methods to secure fan rotors, metal pulleys, plate sprockets, impellers etc. to a shaft.
Shouldered outer diameter allows for easy location
A convenient means to secure fan rotors, steel 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 parts, 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 must be thoroughly cleaned, removing all traces of oil, grease, dirt, and metal filings. Clean the shaft, the bore, the outside of the bushing, and the bore of the hub in which the bush is to be set up into, ensuring 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 assure the bushing has no signals of cracking or fatigue. Place the bushing into the hub and match half holes to make finish holes. It is important to note that the holes need to be matched, not really the threads. Each hole will become threaded using one side only.
Oil threads, the point of the established screws or threads, and beneath the mind 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, after that slide the assembly onto the shaft and locate in the desired position. Insert the correctly sized key in to the shaft keyway, making sure the key is a press match 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 essential oil or lubricant between your taper externally of the bushing and the taper bore of the hub, to that your bushing is being 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 large 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 further. A torque wrench can be 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 before specified torque is attained no longer requires tightening following hammering. IMPORTANT: After a period of running under regular conditions, it is suggested that the application be reviewed to guarantee the torque configurations of the screws are accurate, and do not need re-tightening.
Fill up the holes that are not used in combination with grease or silicone sealant to prevent 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, essential oil threads, and the idea of the established screws or threads, beneath the mind of the cap screws.
Insert screws into the holes that are threaded upon the bushing side, since shown in Physique 2. In sizes where washers are found under the screw head, be sure to use these washers. Please be aware that there should always end up being one screw left over that’s not used when getting rid of the bushing.
Tighten the screws alternately before bushing is loosened in the hub. If the bushing will not loosen instantly, tap on the hub to aid remove.
When installing or removing a Taper Lock bush, it really is imperative that no lubrication be used between your taper. The presence of lubricant on the tapered surfaces is not desirable, as the taper bushing relies on friction to operate successfully, and lubricants decrease friction. use industry standard Part Numbers to identify the specifications of each Taper Lock bush or Taper bush.
