Roller chain 12B-1, pitch 19.05 mm (3/4"), with attachment A1, C45 steel

Product Description

Chain 12B-1 is an industrial-grade simplex roller chain with a pitch of 19.05 mm, designed for use in drives of machines and production equipment. As a Polish manufacturer, we ensure a precise fit of the pin in the bush, which limits the development of play and extends chain service life. The chain is equipped with a bent type A-1 attachment (flight), fitted to selected outer links and used to mount conveyed or driving elements. Ozdowski brand chains offer strength up to 20% higher than the standard requires - each component (pin, roller, plate) is hardened individually before the chain is assembled, which translates into greater durability and resistance to elongation.

Technical data

Applications

Chain 12B with A-1 attachment is used in conveyors, feeders and transport lines, where a flight, partition or other working element mounted on the attachment pushes or lifts the conveyed goods. Typical applications include packaging lines, sorting machines and conveyors in the food industry and agricultural machinery.

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-1 roller chain according to DIN 8187 / ISO 606, single-strand. If the measured chain has these dimensions, the matching product in the Ozdowski range is: roller chain 12B-1, pitch 19.05 mm (3/4"), with attachment A1, C45 steel. The pitch is measured as the distance between the axes of adjacent pins.

How do I select the right roller chain with attachment for an industrial drive?

The key is to determine three parameters of the chain itself: pitch, inner width and roller diameter - for 12B these are 19.05 mm, 11.68 mm and 12.07 mm respectively. In addition, the type and spacing of the attachments must be matched to the machine design.

What is an A-1 attachment and what is it used for?

The A-1 attachment is a single-sided bent attachment with one mounting hole, offset to the side of the link. It is mounted on selected links of the 12B chain to fix conveyed elements, flights, dividers or other working elements to the drive - the exact spacing of the attachments must be matched to the machine design.

What is the difference between a bent and an upright attachment?

The bent attachment (designations without the letter S, e.g. A-1, K-1, WA-2, WK-2) has a plate bent into an L shape and fixed to the side of the chain, close to its axis. The upright attachment (with the letter S, e.g. SA-1, SK-1, WSA-2, WSK-2) has a plate mounted perpendicularly, projecting upwards from the chain. The choice depends on how the flight, divider or other element is fixed in the specific machine.

Why is it not advisable to break a chain with a hammer and punch?

Hammer blows generate uncontrolled forces that can damage the fit of the pin in the plate of the adjacent link, and a ricocheting punch can be dangerous and may damage the roller surface.

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.
