Frequently asked questions

Which chain has a pitch of 19.05 mm (3/4"), a roller of 12.07 mm and an inner width of 11.68 mm?

It is the 12B-3 roller chain according to DIN 8187 / ISO 606, triple-strand (triplex). If the measured chain has these dimensions, the matching product in the Ozdowski range is: roller chain 12B-3, pitch 19.05 mm (3/4"), stainless steel. The pitch is measured as the distance between the axes of adjacent pins.

How do I select a stainless 12B chain for a drive or conveyor?

Three parameters are key: pitch, inner width and roller diameter - for 12B they are 19.05 mm, 11.68 mm and 12.07 mm respectively. In addition, in a corrosive environment it is worth assessing whether standard stainless steel is sufficient or whether the acid-resistant 316L version is needed.

What grade of steel is the stainless chain in this version made of?

The standard stainless version is made of chromium-nickel steel (type 304) containing approx. 18% chromium and 8-10% nickel. It performs well in humid conditions and in the food and pharmaceutical industries, where carbon steel would corrode.

What is the triplex design of a roller chain used for?

A triplex chain consists of three parallel rows of links mounted on common pins. It is chosen when the installation space does not allow a sprocket with a larger pitch and the drive must transmit a higher torque than with the simplex version.

Is excessive chain tension harmful?

Yes - excessive tension overloads the shaft bearings and accelerates pin wear, while a chain that is too slack starts to vibrate (whipping) and its rollers strike the sprocket teeth. The correct tension lies in between.

What does the lead time depend on?

When ordering, please check the current stock level of this chain - 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.
