Roller chain 60H-1 (12AH-1) heavy-duty, ready-made length 3m - connecting link included | Ozdowski

Product Description

Roller chain 12AH-1 (60H-1) L=3000

The 12AH-1 chain is a simplex replacement for drives built to the American inch system - ANSI designation 60H, pitch 19.05 mm. Manufactured in accordance with the standard ANSI B29.1; as a Polish manufacturer, we guarantee dimensional compatibility with sprockets designed to the same standard. 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.

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.

Does fitting a connecting link require special tools?

For normal fitting, pliers or flat-nose pliers are sufficient. When working directly on the machine, it is worth using a chain puller that holds both ends of the chain steady while the connecting link is fitted.

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.
