Profile: Zhejiang Gidi Industrial Chain Co., Ltd. specializes in the production of various kinds of industrial roller, conveyor, engineering & high tensile chains, sprockets, and other power transmission components. We are an ISO 9001 and ISO 14001 certified company. All our products are manufactured as per ISO 606, DIN 8187, JIS or GB international standards. ANSI standard short pitch power transmission roller chains are used for driving, transmission reduction, tension, shuttle traction, and other applications. These chains are produced according to ISO 606A, ANSI B29.1M, and DIN 8188 standards from stainless steel; and incorporated with latest manufacturing technologies. These chains are available from pitch size 6.35 to 76.2 mm in single, multiple and triple strands, riveted or cottered. Transmission chains are used for driving engine, sprocket or other machines. Self-lubricating chain is designed specifically for applications where external lubrication is restricted or prohibited to prevent product contamination, where power transmission and conveyor drives are concealed & often overlooked, or where infrequent maintenance & outdoor exposure cause excessive wear and corrosion. The self-lubricating chain runs smoothly, freely and easily because the oil film prevents damaging corrosion, minimizes tight joints, & eliminates the excessive wear & power loss caused by dry metal-to-metal contact.
