DERK Taper Bush Weld Hub made of steel material to weld with rotating elements like Impellers, Sprockets, Steel Pulley, Rotors, Agitators and many other device for secure mounting assembly.

DERK weld hub are design for use with the universally accepted taper bush made by standard manufacturer.

It is recommended to weld on larger hub diameter D1 and 45 degree continuous weld be used. Do not use excess weld for avoid distortion.

• 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"

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

• 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.

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

• 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.

• 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.

• 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.

• Taper bushing material close cast iron FG20.
• Spheroidal graphite (S.G.) iron for higher stress application.
• As per customer requirement.

DERK Taper Bush Bolt Hub are convenient to mount rotors, Impellers, Agitators and other rotating device with the use of bolts for secure shaft mounting assembly.

DERK Bolt On Hub assembly are design for use with the universally accepted taper bush.
