Chain 12B-1 fi=8 L=40 on one in every 3 pins

Product Description

Roller chain 12B-1 with an extended pin of diameter fi=8 mm and length L=40.5 mm, fitted on every third pin. This is a longer pin version than the L=24 variant, which allows larger or thicker conveyed items to be fixed directly on the chain.

The base chain is manufactured in accordance with PN 77/M-84168 / DIN 8187 (British standard “B”). It is used in industrial and agricultural conveyors and in sorters where flights, dividers or holders need to be fixed on the extended pins.

Frequently asked questions

How should the designation fi=8 L=40 in the chain name be understood?

“fi=8” is the diameter of the extended pin (8 mm), and “L=40” (exactly 40.5 mm) is its length measured from the chain axis to the end of the pin.

What applications is this chain intended for?

For conveyors and transport lines in which flights, holders or elements guiding the conveyed load are mounted on the extended pins.

How often does the extended pin repeat along the chain?

The extended pin fi=8 L=40.5 mm occurs on every third pin; the remaining chain links have the standard 12B-1 design.

Does this chain require a special sprocket?

No, the pitch and roller dimensions comply with the 12B standard, so the chain works with standard sprockets of this size.

Can a section length other than the standard one be ordered?

The chain is available by the running metre - the length is adjusted to the order while keeping a constant spacing of the extended pins.
