Frequently asked questions
Which chain does the 08B-1 z=20 sprocket fit?
08B-1 roller chain to European standard DIN 8187 / ISO 606, with a pitch of 12.7 mm. A simplex sprocket requires a single-strand (simplex) chain.
Which shaft does this sprocket fit?
The sprocket has a finished bore of 16 mm with a keyway, so it is mounted on a 16 mm shaft with a key. Before ordering, it is worth measuring the shaft carefully with a caliper in several places.
Does it fit ASA 40 chain?
No. ASA 40 chain (American standard) has the same pitch, but a different roller diameter (7.94 mm instead of 8.51 mm) and a different inner width (7.94 mm instead of 7.75 mm). The 08B sprocket is designed for European-standard chain, so the two systems should not be mixed.
Can a new chain be fitted on a worn sprocket?
This should not be done. A worn sprocket has a changed tooth profile, so a new chain runs unevenly and elongates quickly. The rule is: new chain - new sprockets.
What causes wear on the sides of the teeth?
Most often misaligned sprockets. The chain does not run straight and its plates rub against the sides of the teeth. In this case the sprockets must be realigned in one plane.
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.
