Frequently asked questions
Which chain does this sprocket fit?
ASA 120-1 (24A-1) roller chain with a pitch of 38.1 mm. A simplex sprocket requires a single-strand (simplex) chain.
How do I check sprocket run-out after installation?
A dial indicator on a magnetic stand is used. Place the tip against the rim or side of the sprocket and turn the shaft, reading the deviations. Excessive run-out usually means a crooked bore or a damaged shaft.
How should a sprocket be protected before a longer machine standstill?
After cleaning with a brush and technical cleaner, coat the whole surface of the sprocket with preservative grease or thick spray oil that displaces moisture. This protects the C45 steel against corrosion during downtime, for example out of season.
How does tooth wear affect machine operation?
Worn teeth make the chain engage the sprocket unevenly and abruptly. This causes vibrations that are passed on to shafts and bearings and accelerate wear of the whole drive.
How do I check the pitch of a sprocket?
The sprocket pitch matches the chain pitch - it is the distance between the centres of adjacent teeth measured on the pitch circle. The easiest way to check it is to place a section of matching chain on the sprocket: it should sit on the teeth without tension. This sprocket has a pitch of 38.1 mm (1 1/2").
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.
