Roller chain 60H-1 (12AH-1) heavy-duty, ready-made length 4m - connecting link included | Ozdowski

Product Description

Roller chain 12AH-1 (60H-1) L=4000

This simplex roller chain bears the designation 12AH-1 (ANSI 60H) and operates at a pitch of 19.05 mm, typical of the drives of machines imported from the USA. The pin, roller and plate are hardened separately before the link is assembled - the approach on which we, as a European manufacturer, build the durability of the entire American series. Ozdowski chains withstand loads approx. 20% higher than the standard minimum - this is the result of individual hardening of each component (pin, roller, plate) before the chain is assembled.

Technical data

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 correct chain tension so important for its service life?

A chain that is too slack starts to vibrate (whipping), causing the rollers to strike the sprocket teeth. Excessive tension, on the other hand, overloads the shaft bearings and accelerates pin wear - in both cases the service life of the drive is reduced.

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.
