Description
ANSI A series corrosion-resistant roller chain
EP-100ZP Zinc-Plated Roller Chain
EP-100ZP follows the ANSI A series dimensions shown in the supplied corrosion-resistant chain sample. The sample presents this family as corrosion-resistant zinc-plated chain. The chain is intended for general outdoor drives, agricultural machinery, humid production areas, rain-exposed conveyors, and utility equipment where the selected finish, lubrication method, sprocket condition, and maintenance plan are reviewed together.
The model number is prefixed with EP- for this website while preserving the original dimensional designation.

Sample-Based Construction Notes
Duplex and triplex zinc-plated chains are available in the listed sizes. Double-pitch zinc-plated conveyor chains are available upon request.
For the sizes marked as bush chain, d1 is the external diameter of the bush. The 06B family is shown with straight side plates. These construction notes should be retained when preparing drawings, replacement checks, and RFQ documentation.
Matching Sprockets, Links and Drive Components
Pair EP-100ZP with a 100 chain sprocket made for the same dimensional family and strand count. Use connecting links and offset links with the same specified finish. Check sprocket tooth hooks, root wear, shaft runout, center distance, guarding, and lubrication access before commissioning.
Application Guidance
In the United States and Australia, buyers commonly review coated chains for agricultural and outdoor equipment exposed to rain, fertilizer residue, dust, and seasonal storage. German and Nordic projects often require clear coating declarations and machinery risk documentation. Japanese buyers frequently place strong emphasis on dimensional records, replacement drawings, and controlled maintenance procedures.
ASTM B117 is a controlled salt-fog test method and does not convert test hours directly into outdoor service life. Where a corrosion test is required, state the exact method, specimen, acceptance criterion, and coating chemistry in the purchase specification.

Questions Buyers Ask
What dimensions define EP-100ZP?
The sample lists pitch P 31.750 mm, roller or bush diameter d1 19.05 mm, width between inner plates b1 18.90 mm, pin diameter d2 9.53 mm, maximum pin length L 40.40 mm, maximum connecting-pin length Lc 44.70 mm, inner plate depth h2 30.00 mm, and plate thickness t/T 4.00 mm.
What is the breaking load of EP-100ZP?
The sample lists a breaking load of 88.50 kN / 20114 lbf. This value is not a working-load rating; drive selection must consider speed, shock, lubrication, sprockets, alignment, and duty cycle.
Can EP-100ZP be supplied as duplex or triplex chain?
Duplex and triplex zinc-plated chains are available in the listed sizes. Double-pitch zinc-plated conveyor chains are available upon request.
Which sprocket should be used with EP-100ZP?
Use a correctly manufactured 100 chain sprocket for the ANSI A series, matched to the strand count. Inspect tooth wear and alignment before installing a new chain.
