This is a technical engineering drawing/blueprint for a C2162H rivet roller chain assembly manufactured by U.S. Tsubaki, Inc. The document specifies a complete chain assembly (Part PS92) measuring 42 feet 8 inches in length with 128 pitches and 8.0-inch typical spacing between components.

The drawing details material specifications and component requirements: chain links must be epoxy-coated before assembly with low-gloss black epoxy powder coating and electrostatically applied; all pins must be nitronic 60 stainless steel per ASTM A276 Type UNS S21800 with minimum HRB 95 hardness; bushings must be 17-4 PH stainless steel per ASTM A564; all rolls must be carbon steel case hardened; and cotters must be type 302 stainless steel. Manufacturing tolerances are precisely defined, including maximum per-foot tolerance of ±.025 inches, maximum variation between matched chain pairs of ±.030 inches, and maximum backlash per foot of .025 inches. Chains are prestressed in matched pairs with a 42-foot 8-inch chain length. The assembly incorporates numbered components including pins, cotters, bushings, rolls, and cotter keys, with dimensions and specifications provided in the accompanying parts list (items 1-9). No lubrication is permitted during any manufacturing process. The drawing is dated 11/28/85 and carries revision code C with drawing number B-101-0944.
