Corrosion-Resistant Roller Chain Built from the Supplied Sample

The product system follows the sample families for Dacromet-plated, zinc-plated and nickel-plated chains. Each family includes ANSI A and ISO B dimensions. Product pages retain the sample fields for pitch, roller or bush diameter, inner width, pin diameter, pin lengths, plate depth, plate thickness, breaking load and weight per meter.

Field Meaning How it is used
P Pitch Primary chain and sprocket size reference
d1 Roller diameter; external bush diameter on marked bush chains Confirms roller-seat and sprocket compatibility
b1 Width between inner plates Checks sprocket tooth and side-clearance fit
d2 Pin diameter Part of the chain construction reference
L / Lc Maximum pin lengths Checks overall width and connecting-link clearance
h2 Inner plate depth Used for envelope and guarding checks
t/T Plate thickness Construction and side-clearance reference
Q Breaking load Not a working-load rating; selection still requires duty data
q Weight per meter Useful for handling and drive-system calculations

The sample also notes duplex and triplex availability across the listed sizes and double-pitch conveyor versions by request. Dacromet-plated chain is described for corrosive conditions. Nickel-plated chain is described for outdoor exposure such as rain. Zinc-plated chain is presented as a corrosion-resistant plated option.

Customer Reviews & Case Studies

United States – Outdoor equipment

Use: coating and dimensional-family review for rain, dust and seasonal storage.

Feedback: The project team used the dimensional table to confirm pitch, roller diameter, inner width and matched sprocket geometry.

Application fit: ★★★★★

Germany – Industrial machinery

Use: Coated-chain replacement with documented guarding and maintenance access.

Feedback: Clear coating identification and exact chain dimensions helped the integrator prepare the technical file.

Application fit: ★★★★★

Japan – Precision automation

Use: Compact drive exposed to rain or periodic washdown.

Feedback: The buyer emphasized dimensional traceability, link configuration and sprocket condition.

Application fit: ★★★★☆
