Chain 12B-1 with WK2 attachment

Product Description

Roller chain 12B-1 with WK2 attachment

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. A WK-2 attachment is fitted to selected outer links - an L-shaped bent plate used to mount flights, partitions or other working elements of the conveyor. The Ozdowski brand hardens pins, rollers and plates individually, before the links are assembled into a complete chain - as a result, our chains are approx. 20% stronger than the standard requires and therefore more durable and robust when working under load.

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 WK-2 attachment and what is it used for?

The WK-2 attachment is a widened bent attachment with two mounting holes. 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.

Are the chain plates additionally protected against corrosion?

Depending on the selected version, the links may have blackened, phosphated, nickel-plated or galvanised plates. Even in the basic industrial version, the links are factory-lubricated, which provides additional temporary protection against corrosion.

Where is this product used?

Chain 12B with WK-2 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.
