Sprocket 24B-1 z=38 for Taper-Lock bush 3030, cast iron

Product Description

Sprocket 24B-1 z=38 for Taper-Lock bush 3030, cast iron works with 24B-1 roller chain (European standard DIN 8187 / ISO 606), single-strand (simplex), with a pitch of 38.1 mm (1 1/2"). It has 38 teeth and is made of EN-GJL-250 cast iron.

The sprocket has a seat for a Taper-Lock 3030 clamping bush, so it can be mounted on the shaft without boring the hole or cutting a keyway in the sprocket - simply choose a 3030 bush with a bore that matches the shaft. The hub diameter is 160 mm and the total width of the sprocket is 76 mm. The bush is not included - the 3030 bush can be purchased separately from our range.

Technical data

Applications

It works well in high-power agricultural machinery, presses and drives in processing plants. 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-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 38.1 mm. A simplex sprocket requires a single-strand (simplex) 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.

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.

Can a Taper-Lock bush be used on a shaft without a keyway?

The bush holds on the shaft by friction, but in drives transmitting high torque a key is an essential safeguard. Bushes with larger bores have a standard keyway to DIN 6885.

What does the lead time depend on?

When ordering, please check the current stock level of this sprocket - the lead time depends on it and is clearly stated according to the quantity available in each warehouse. The stock level is shown above the product price and may vary depending on the warehouse.
