Taper Bushes


Application

  • Allow easy installation application for any rotating parts (Rotors, Pulleys, Sprockets, Impellers) to a shaft.

  • Approx weight in kg for a minimum bore size

  • A taper bushing is deigned by 4 digit representing two numbers, The first numbers represent the maximum bore size ( in Inches), The second numbers represent the bushing length( In Inches).

  • For example : A 1008 has a max bore of 1.0" and total Length is 0.875"


Installation Remove

  • Do not use lubricants or anti seize compounds on bushing and hub mounting area.


Quick installation

  • Insert bush in hub with align drilled holes of bushing with tapped holes in hub.

  • Greasing thread and point of grub screw or in cap crews greasing threads and under head. Insert screws through tapped holes in pulley hub and thread loosely.

  • Position assembly on shaft and tighten screws progressively and uniformly until obtain fully secured grip.

  • After drive has been running under load for a short time stop and check tightness of screws.

  • Fill empty holes with grease to exclude dirt.


Fast Remove

  • Remove screws from hub and thread in to tapped holes in bushing, tighten alternately until bushing free from hub.

  • Remove assembly from shaft.


Tapered precision fit

  • Precision machining of the tapered bore in the component the tapered mating surface of the bushing insures a snug, precision fit between rim and bushing.


Fully interchangeable with other TB Bushings

  • As in the case of Derk Taper bushings & pulleys also conform to standardize in dimensions, because of this feature and stock bushing may be interchanged with the same size bushing.


Important Reminder

  • All operational power transmission products when used in a drive are potentially dangerous and must be guarded by the user as required by applicable laws, regulations standards and good safety practice.


Bushing Material

  • Taper bushing material close cast iron FG20.

  • Spheroidal graphite (S.G.) iron for higher stress application.

  • As per customer requirement.
