Chain 12B-1 galvanised

Product Description

Roller chain 12B-1 galvanised

Chain 12B-1 (simplex) is a proven solution for power transmission in mechanical systems, made with a pitch of 19.05 mm. Pins, rollers and plates are hardened separately before assembly - as a Polish manufacturer we treat this as standard, which means the chain retains its original dimensions for a long time and does not "stretch" under load. Ozdowski chains withstand loads approx. 20% higher than the standard minimum - this is the result of individual hardening of each component (pin, roller, plate) before the chain is assembled.

Technical data

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 12B these are 19.05 mm, 11.68 mm and 12.07 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 corrosion protection does galvanising provide?

The zinc coating protects the links against corrosion in conditions of increased humidity, e.g. outdoors or near washing stations.

When should automatic tensioners be used, and when fixed chain guides?

Automatic (spring-loaded) tensioners work well in drives with variable loads and high speeds, whereas fixed plastic chain guides are most often used in drives with a stable, repetitive duty cycle.

Do roller chains from the Ozdowski range comply with DIN 8187?

Yes. Our chains fully comply with the stringent European standard DIN 8187 / ISO 606, which ensures a correct fit with sprockets made to the same standard.

Where is this product used?

The chain is used in production machine drives, transport conveyors, industrial mills and mixers, sorting lines and in maintenance as a replacement part for existing chain drives.
