Chain 12B-1 with WSK2 attachment

Product Description

Roller chain 12B-1 with WSK2 attachment

Roller chain 12B-1 is a simplex chain with a pitch of 19.05 mm, used as a basic drive element in mechanical engineering. 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 fitted with a WSK-2 type attachment (pusher) in an upright design, mounted on selected outer links and projecting above the chain plate. 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 the WSK-2 attachment and what is it used for?

The WSK-2 attachment is a widened upright 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.

Why does hardening each component (pin, roller, plate) before assembly increase chain service life?

Many low-cost suppliers harden the chain only after assembly, which causes uneven hardening and brittle links. Separate hardening of the pin, roller and plate provides uniform hardness and less wear during operation.

Where is this product used?

The 12B chain with WSK-2 attachment is used in conveyors, feeders and transport lines, where a pusher, partition 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.
