  • 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.
