taper lock bush

Remove all screws, essential oil threads, and the idea 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, since shown in Physique 2. In sizes where washers are found beneath the screw head, make certain to make use of these washers. Please be aware that there should always be one screw left over that’s not used when eliminating 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 assist remove.
When installing or removing a Taper Lock bush, it is imperative that no lubrication be used between your taper. The presence of lubricant on the tapered surfaces is not desired, as the taper bushing depends on friction to operate efficiently, and lubricants reduce friction. use industry standard Component Numbers to identify the specifications of each Taper Lock bush or Taper bush.

It is the most successful shaft fixing in the market place today with a complete range of both metric and imperial sizes as well as a full selection of weld-on hubs, bolt-on hubs and hub adaptors.

Keyed version also available 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 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 outside of the bushing, and the bore of the hub in which the bush is usually to be installed into, making sure the bush is taken off the hub, should it already be installed.
Check the bushing to make sure all surfaces are free from nicks and burrs, and ensure the bushing has no symptoms of cracking or fatigue. Place the bushing into the hub and match half holes to make complete holes. It is necessary to notice that the holes have to be matched, not really the threads. Each hole will end up being threaded on one side only.
Oil threads, the idea of the set screws or threads, and beneath the head of the cap screws. Then place the screws loosely into the holes that are threaded on the hub-side
Ensure that the Taper Lock bush is totally free in the hub, after that slide the assembly onto the shaft and locate in the required 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 your 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 externally of the bushing and the taper bore of the hub, to that your 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.
Using a hammer and prevent, 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 is seated squarely. The screws are then tightened additional. A torque wrench is utilized to tighten the screws alternatively and evenly until they are all to the suggested torque setting.
Continue doing this alternate hammering and screw tightening until the specified torque is attained and no longer requires tightening following hammering. IMPORTANT: After a period of running under regular conditions, it’s advocated that the application be reviewed to guarantee 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.
