High-Precision, High-Strength Roller Drive Chains (PRN, PRT)

Designation: PRN, PRT
PRN and PRT chains are roller drive chains of increased precision and strength. They are made to tighter manufacturing tolerances and from higher-grade steel, which raises the breaking load and extends service life compared with standard PR chains. They are used in drives with elevated requirements for accuracy, speed and durability. PRN denotes the high-strength version, PRT the heavy-duty version. We supply to GOST and manufacture to customer drawings.

Supply and custom manufacturing. We work with VAT.
Exact parameters and pricing are confirmed via the request form.
