Sprocket 24B-2 z=76 for Taper-Lock bush 4040, cast iron

Product Description

Sprocket 24B-2 z=76 for Taper-Lock bush 4040, cast iron fits 24B-2 roller chain (European standard DIN 8187 / ISO 606), double-strand (duplex), with a pitch of 38.1 mm (1 1/2"). It has 76 teeth and is made of EN-GJL-250 cast iron.

The sprocket has a seat for a Taper-Lock 4040 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 4040 bush with a bore that matches the shaft. The hub diameter is 240 mm and the total width of the sprocket is 102 mm. The bush is not included - the 4040 bush can be purchased separately from our range.

Technical data

Applications

It is used in sawmills, cement plants and bulk material handling lines. The double-strand version carries higher loads than a single-strand one of the same pitch. The cast iron design works well for large sprockets in reduction gears, where rigidity and vibration damping matter.

Frequently asked questions

Which chain does this sprocket fit?

24B-2 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 38.1 mm. A duplex sprocket requires a double-strand (duplex) chain.

Does it fit ASA 120 chain?

No. ASA 120 chain (American standard) has the same pitch, but a different roller diameter (22.22 mm instead of 25.4 mm). The 24B sprocket is designed for European-standard chain, so the two systems should not be mixed.

How do I mount a sprocket with a Taper-Lock bush?

Insert the bush into the sprocket seat, align the holes and lightly screw in the screws. Then slide the assembly onto the shaft and tighten the screws alternately until the bush is firmly clamped on the shaft.

Can the bush taper be greased before mounting?

No. The bush works by friction, and grease on the tapered surfaces can cause the bush to be drawn in too deep and crack the sprocket hub. The tapered surfaces must be degreased before mounting.

How do I remove a sprocket with a Taper-Lock bush?

Remove the mounting screws and screw one of them into the free dismounting hole. The screw then acts as a puller and pushes the bush out of the sprocket seat.

What does the lead time depend on?
