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.
