Roller chain 08B-2, pitch 12.7 mm (1/2"), with attachment WSA2 on every second outer link, C45 steel

Product Description

Roller chain 08B-2 (duplex, pitch 12.7 mm) is a drive component used where durability and dimensional repeatability matter. Pins, rollers and plates are hardened separately before assembly - as a European manufacturer, we treat this as standard, so the chain retains its original dimensions for a long time and does not "stretch" under load. The chain is fitted with an upright WSA-2 type attachment (carrier), mounted on selected outer links and projecting above the chain plate. The attachment is mounted on every second outer link. 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

Applications

The 08B chain with WSA-2 attachment is used in conveyors, feeders and transport lines, where a flight, divider or other working element fixed to 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 12.7 mm (1/2"), a roller of 8.51 mm and an inner width of 7.75 mm?

It is the 08B-2 roller chain according to DIN 8187 / ISO 606, double-strand (duplex). If the measured chain has these dimensions, the matching product in the Ozdowski range is: roller chain 08B-2, pitch 12.7 mm (1/2"), with attachment WSA2 on every second outer link, 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 08B these are 12.7 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 the WSA-2 attachment and what is it used for?

The WSA-2 attachment is a widened upright attachment with one mounting hole. It is mounted on selected links of the 08B 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.

What is the purpose of the duplex design in a roller chain?

A duplex chain consists of two parallel rows of links mounted on common pins. It is chosen when the installation space does not allow a sprocket with a larger pitch and the drive must transmit a higher torque than with the simplex version.

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.
