Drive Chains
Roller Drive Chains with Offset Plates (PRI)
Designation: PRI
PRI chains with offset plates are used in heavily loaded drives that operate in harsh weather and process conditions. The plate shape is designed for assemblies subject to significant impact loads: under force the plate may deform slightly, but the chain retains its integrity and does not fail.
When selecting, the pitch, plate height, roller and pin diameters and the distance between plates are important. The breaking load of these products is in the 360–1200 kN range. We supply to GOST and to in-house company standards, and provide a warranty on all products. Manufactured to customer drawings.
Supply and custom manufacturing. We work with VAT.
