Chain 20B-3

Product Description

Roller chain 20B-3

The 20B-3 chain (triplex) is a proven solution for power transmission in mechanical systems, made with a pitch of 31.75 mm. Manufactured in accordance with DIN 8187 / ISO 606; as a Polish manufacturer, we guarantee full dimensional compatibility with sprockets made to the same standard. In Ozdowski chains, each component is hardened separately before being assembled into a finished link - which is why their actual strength exceeds the requirements of the standard by about 20%, meaning greater durability and resistance to breaking.

Frequently asked questions

How do I choose the right roller chain for an industrial drive?

The key is to determine three parameters: pitch, inner width and roller diameter - for 20B these are 31.75 mm, 19.56 mm and 19.05 mm respectively. In addition, operating conditions should be taken into account: load, rotational speed and environment (dust, moisture), in order to select the right version.

What is a triplex chain and when is it used?

A triplex chain is a design consisting of three parallel rows of links connected by common pins. It is used where the space for sprockets is limited (a wider sprocket with a larger pitch cannot be used) and the drive must transmit a higher torque than in the simplex version.

How can industrial chains be cleaned of dirt and mud without damaging the links?

Avoid aggressive acid cleaners and pressure washers at close range, as water can be forced under the rollers. Dedicated cleaning agents and soft brushes are a better solution.

Are the chain plates additionally protected against corrosion?

Depending on the selected version, the links may have blackened, phosphated, nickel-plated or galvanised plates. Even in the basic industrial version, the links are factory-lubricated, which provides additional temporary protection against corrosion.

Where is this product used?

This chain is used in industrial machine transmissions, hoists and lifts, conveyor drives and agricultural machinery - wherever repeatable performance under load matters.
