Taper Lock Bush Manufacturer in Ahmedabad
Bushes and hubs
Fit and remove a pulley in minutes
Taper lock bushes in standard sizes from 1008 to 5050, for fast, concentric mounting of pulleys, sprockets and gears on plain shafts. Bored with keyway, in metric or inch sizes.
A taper lock bush is a split, tapered sleeve that locks a pulley, sprocket or gear onto a plain shaft. Tightening the grub screws draws the bush into the matching taper in the hub and clamps it to the shaft. To remove it, a screw goes into the removal hole and pushes the bush back out.
Because the bush carries the bore, one hub fits a range of shaft sizes with no reboring. Taper lock bushes fit V belt pulleys, timing pulleys, sprockets and gears with taper bored hubs.

Fitting
How a taper lock bush locks and releases
-
Clean and fit
Clean the taper, put the bush in the hub and line up the half holes.
-
Insert the screws

FAQ
Taper lock bushes: common questions
Quick answers for maintenance and purchase teams.
The first two digits give the approximate maximum bore and the last two the approximate length, both in tenths of an inch. A 1610 bush takes bores up to about 1.6 in (42 mm) and is about 1.0 in long.
Choose the size whose maximum bore covers your shaft and that matches the taper in your hub. The size table lists the stock metric and inch bores for each bush.
Fit the bush in the hub, insert the grub screws in the fitting holes and tighten them evenly. To remove it, move a screw to the removal hole and tighten it to push the bush out of the taper.
Taper lock bushes sit flush in the hub, while QD bushes have a flange and pull up with cap screws. The two are not interchangeable, so match the bush to the hub you have.
Yes. Each bush size is made with metric or inch bores up to its maximum, with a standard keyway.
