Chain 212B-1 stainless

Product Description

Roller chain 212B-1 stainless

The stainless 212B-1 chain is a simplex chain with an extended (double) pitch 38.1 mm, designed for slow-running conveyors operating in a corrosive environment. Manufactured in accordance with the standard DIN 8187 / ISO 606 for double-pitch chains; as a European manufacturer, we keep the same roller, pin and plate dimensions as in the 12B chain with standard pitch. Ozdowski brand chains offer strength up to 20% higher than the standard requires - each component (pin, roller, plate) is hardened individually before the chain is assembled, which translates into greater durability and resistance to elongation.

Technical data

Frequently asked questions

How do I select a stainless 212B chain for a drive or conveyor?

Three parameters are key: pitch, inner width and roller diameter - for 212B they are 38.1 mm, 11.68 mm and 12.07 mm respectively. In addition, in a corrosive environment it is worth assessing whether standard stainless steel is sufficient or whether the acid-resistant 316L version is needed.

Why are extended (double) pitch chains used instead of ordinary single-pitch chains?

For the same conveyor length, the chain has half as many links, pins and rollers as the single-pitch version, which reduces cost and weight - worthwhile in slow-running drives where the high pitch precision typical of high-speed transmissions is not required.

Does a chain with extended (double) pitch fit standard sprockets?

No - it requires a sprocket designed for double pitch (every second tooth engaged). It must not be confused or interchanged with a standard-pitch chain of the same base designation.

What grade of steel is the stainless chain in this version made of?

The standard stainless version is made of chromium-nickel steel (type 304) containing approx. 18% chromium and 8-10% nickel. It performs well in humid conditions and in the food and pharmaceutical industries, where carbon steel would corrode.

Where is this product used?

Extended-pitch chains are used in slow-running conveyors, transport accumulators and packaging and bottling lines - the stainless version additionally in washing systems, the food industry, and dryers and ovens operating at elevated temperatures.
