Chain 12B-1 with attachment K1

Product Description

Roller chain 12B-1 with attachment K1

Roller chain 12B-1 (simplex, pitch 19.05 mm) is a drive component used where durability and dimensional repeatability matter. As a European manufacturer, we ensure a precise fit of the pin in the bush, which limits the development of play and extends chain service life. A K-1 attachment is mounted on selected outer links - an L-shaped bent plate used to fix flights, dividers or other working elements of the conveyor. In Ozdowski chains, each component is hardened separately before being assembled into a finished link - which is why their actual strength exceeds the requirements of the standard by about 20%, meaning greater durability and resistance to breaking.

Technical data

Frequently asked questions

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 a K-1 attachment and what is it used for?

The K-1 attachment is a bent attachment with two mounting holes, positioned centrally on 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 does "dry" running shorten the service life of rollers and pins?

Lubrication reduces metal-to-metal friction in the joints and dissipates heat. Running without lubricant leads to micro-seizures and faster heating of the pins, which accelerates link wear.

Where is this product used?

The 12B chain with K-1 attachment is used in conveyors, feeders and transport lines where a flight, divider or other working element fixed to the attachment moves or lifts the conveyed goods. Typical applications include packaging lines, sorting machines and conveyors in the food industry and agricultural machinery.
