Chain 12B-3 stainless

Product Description

Roller chain 12B-3 stainless

This triplex roller chain 12B-3 is made of stainless steel and has a pitch of 19.05 mm. Manufactured in accordance with the standard DIN 8187 / ISO 606; as a European manufacturer, we guarantee dimensional compatibility with sprockets of the same standard, regardless of the material. 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.

Technical data

Frequently asked questions

How do I select a stainless 12B chain for a drive or conveyor?

Three parameters are key: pitch, inner width and roller diameter - for 12B they are 19.05 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.

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.

What is the triplex design of a roller chain used for?

A triplex chain consists of three parallel rows of links mounted on common pins. It is chosen when the installation space does not allow a sprocket with a larger pitch and the drive must transmit a higher torque than with the simplex version.

Is excessive chain tension harmful?

Yes - excessive tension overloads the shaft bearings and accelerates pin wear, while a chain that is too slack starts to vibrate (whipping) and its rollers strike the sprocket teeth. The correct tension lies in between.

Where is this product used?

Used on conveyors and in packaging machines in food and pharmaceutical plants, as well as in rooms with high humidity where ease of cleaning is required.
