Chain 208B with A1 attachment

Product Description

Roller chain 208B with A1 attachment

Chain 208B-1 (simplex) is a proven solution for power transmission in mechanical systems, made with a pitch of 25.4 mm. Manufactured in accordance with DIN 8187 / ISO 606; as a European manufacturer, we guarantee full dimensional compatibility with sprockets made to the same standard. An A-1 attachment is fitted to selected outer links - an L-shaped bent plate used to mount flights, partitions 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.

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 208B these are 25.4 mm, 7.75 mm and 8.51 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 208B 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?

A double-pitch chain with attachments is used in accumulation conveyors, packaging lines and feeders, where a pusher or divider mounted on the attachment transports individual items at regular intervals - the larger pitch allows the use of fewer links and sprockets of larger diameter.
