Drive Chains
Roller Drive Chains (PR)
Designation: PR
A roller drive chain (PR) transmits force between shafts in a wide variety of machines and mechanisms. It is assembled from alternating inner and outer links — plates, pins, bushings and rollers — so the chain stays flexible and withstands high loads. With regular maintenance and lubrication, the product retains its working properties for many years.
Why this chain type is chosen:
• transmits power almost without losses — efficiency up to 98%;
• dimensions and strength comply with GOST requirements;
• smooth running, without jerks or jamming;
• easy to repair — a worn link can be replaced individually.
Such chains are in demand in materials-handling equipment, drilling rigs, agricultural machinery and other industrial units. We supply GOST sizes and manufacture chains to order to customer drawings.
Supply and custom manufacturing. We work with VAT.
