Roller chain 60H-1 (12AH-1) heavy-duty, ready-made length 5m - connecting link included | Ozdowski

Product Description

Roller chain 12AH-1 (60H-1) L=5000

Simplex roller chain 12AH-1 (ANSI 60H, pitch 19.05 mm) is used as a replacement part in drives with inch dimensions. The pin, roller and plate are hardened separately before the link is assembled - this is the approach on which we, as a Polish manufacturer, build the durability of the entire American series. 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 you choose the correct ANSI roller chain pitch for a drive?

Three parameters determine the correct selection: pitch, inner width and roller diameter - for 12AH (ANSI 60H) they are 19.05 mm, 12.57 mm and 11.91 mm respectively. It is also worth considering the load, rotational speed and operating environment (dust, moisture) in order to choose the right version.

How does an AH (reinforced) chain differ from the standard version of the same pitch?

The AH version has the same pitch, inner width and roller diameter dimensions as the standard 12A (it works with the same sprockets), but uses thicker side plates - 3.2 mm compared with 2.4 mm in the standard version. As a result, the chain copes better with jerky loads and operation in more demanding conditions.

Can a section length other than the standard lengths listed be ordered?

Yes. As standard, we offer ready, convenient sections in lengths of 1, 2, 3, 4 and 5 metres, but the chain can also be ordered by the running metre, or several sections can be joined with a connecting link to obtain the required total length - remembering to keep an even number of links.

Why is it better to use a chain breaker rather than a hammer to separate a chain?

A chain breaker pushes the pin out axially and in a controlled manner, without the risk of deforming the side plates. Hammer blows generate uncontrolled forces that can damage the pin fit in the adjacent link.

Where is this product used?

The thicker side plates of this version are fitted in CLAAS combine harvesters (Dominator, Mega, Commandor) and in other agricultural machines operating under higher dynamic loads than a typical industrial drive.
