Acid-resistant chain 12B-1 fi=8 L=40 on every 4 pins

Product Description

Acid-resistant roller chain 12B-1 made of 316L stainless steel, with an extended pin of diameter fi=8 mm and length L=40.5 mm, occurring on every fourth pin. The wider spacing of the extended pins compared with the "every 3" variant works well where accessory mounting points can be spaced further apart, e.g. with longer flights or dividers.

The base chain is made in accordance with PN 77/M-84168 / DIN 8187 (British standard "B"), and the material - 316L steel - ensures durability in humid and hygienic environments such as the food or chemical industries, as well as in sorting machines.

Frequently asked questions

How does this chain differ from the "every third pin" version?

The design and dimensions of the pin (fi=8, L=40.5 mm) are the same, only the spacing differs - here the extended pin repeats on every fourth pin, i.e. less frequently.

What material is this chain made of?

Acid-resistant stainless steel 316L, resistant to corrosion and the effects of moisture and cleaning agents.

Where is this chain used?

In conveyors operating in the food and chemical industries and other environments that require corrosion resistance combined with mounting accessories on the pins.

What do the values fi=8 and L=40 in the name mean?

"fi=8" is the diameter of the extended pin in millimetres, and "L=40" (exactly 40.5 mm) is its length measured from the chain to the end of the pin.

Do standard 12B sprockets fit this chain?

Yes, the geometry of the acid-resistant 12B-1 chain complies with the 12B standard, so it works with standard sprockets of this size.
