Acid-resistant chain 12B-1 fi=8 L=40 on every 3 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, placed on every third pin. 316L steel provides high resistance to corrosion, moisture and cleaning agents, making the chain suitable for environments with increased hygiene requirements.

The geometry of the base chain complies with PN 77/M-84168 / DIN 8187 (British standard "B"). It performs well in the food and chemical industries, in sorting machines and wherever corrosion resistance combined with the ability to mount accessories on protruding pins is required.

Frequently asked questions

Why is this chain acid-resistant?

It is made of 316L stainless steel, which remains corrosion-resistant even in contact with moisture, water or the cleaning agents used to wash installations.

Which industries is this chain intended for?

Primarily the food and chemical industries, and anywhere a standard steel chain would corrode, e.g. in humid production halls.

What does fi=8 L=40 mean for this model?

"fi=8" is the diameter of the extended pin (8 mm), and "L=40" (exactly 40.5 mm) is its length - the pin protrudes above the chain plates, allowing accessories to be mounted.

How often does the extended pin occur?

The extended pin appears on every third pin; the remaining links have the standard design of the acid-resistant 12B-1 chain.

Does this chain work with standard 12B sprockets?

Yes, the chain geometry complies with the 12B standard, so it works with standard sprockets of this size without any additional modifications.
