WR78 is constructed with offset sidebars \u2014 each link’s sidebar is bent at an angle that causes adjacent links to interlock at their crossing points. The offset geometry provides a tighter, more compact chain construction that is resistant to twisting under off-axis loads. The “R” indicates the standard (regular) construction. WR78 is the most common specification for agricultural drag conveyors, grain elevators, and light industrial drag chain applications.<\/div>\n<\/div>\n

WH78 uses a heavier sidebar cross-section than WR78 \u2014 the “H” indicates heavy construction. Same 2.609-inch pitch, same barrel diameter (0.875 inches), same tooth face (1.000 inch), making WH78 directly compatible with the same sprockets as WR78. WH78 is specified when the application requires higher breaking load \u2014 cement plant raw material conveyors, steel slag handling, and industrial applications where impact loading exceeds the WR78 rating. Both chains use identical sprockets: any sprocket listed as WH78-A also works with WR78.<\/div>\n<\/div>\n<\/div>\n

Brass idler bodies are specified for wet or corrosive environments where steel would corrode. Nylon bodies are used where weight reduction matters. UHMW bodies (with the lowest friction coefficient) are the preferred specification for idler positions in cement and aggregate applications where abrasive dust contacts the sprocket \u2014 UHMW resists abrasive wear better than nylon at these contact conditions. All three materials are available with the standard WR78\/WH78 tooth profile and any bore size within the sprocket’s maximum bore limit.<\/p>\n

\"WR78<\/p>\n

Korean conveyor equipment fabricators building custom drag and bucket conveyors for industrial clients use split-for-welding WH78 A-plate sprockets where the shaft is a fabricated component rather than a machined shaft. The weld-in construction is integral to the conveyor design, allowing the sprocket to be sized and positioned precisely during fabrication. Both WR78 and WH78 chain compatibility ensures the client’s existing chain is supported.<\/p>\n<\/div>\n<\/div>\n

No. 81X chain is an ANSI engineer class roller chain with a 2.609-inch pitch but a different roller diameter and link geometry from WR78\/WH78 welded steel chain. The sprocket tooth profile is designed for a different chain cross-section. An 81X sprocket’s tooth form does not correctly seat the WH78 chain barrel (0.875-inch diameter), and a WH78 sprocket’s barrel seat does not match the 81X chain’s roller geometry. The identical pitch is coincidental \u2014 the chain and sprocket systems are not interchangeable. Always verify the chain designation before ordering sprockets.<\/div>\n<\/div>\n
\n
What is the “shroud diameter” in the specification table?<\/div>\n
The shroud diameter is the outside diameter of the smooth cylindrical surface between the tooth tips \u2014 it is the diameter that the chain links ride over as they approach the tooth engagement zone. In welded steel chain, the chain link’s inner guide rail contacts this shroud surface as the chain wraps onto the sprocket, centring the chain laterally on the sprocket face. The shroud diameter must be smaller than the chain link’s inner gauge dimension to allow correct chain seating. This dimension is important when designing the conveyor trough to ensure the sprocket clears the trough walls at the chain inlet.<\/div>\n<\/div>\n
