WH111 vs WR111 Chain
WR111 and WH111 chain directly interchange with each other dimensionally and are both equally as popular. However, when taking a closer look there are differences. WR111 does not implement fully heat-treated components, thus it has a much quicker wear life and a lower tensile strength rating. Because of this we primarily recommend WH111 chain!
WR111 Tensile Strength - 50,400 lbs
WH111 Tensile Strength - 91,000 lbs (+40,600 LBS)
Made in USA WR111 Chains
Something that really sets USA Roller Chain and Sprockets apart from other suppliers in the industry is our lineup of domestically manufactured chains. We supply a Made in USA WR111 chain for almost the same price as an import chain, the benefit of domestic welded steel chains boils down to the metallurgy and workmanship/ quality control. Domestic steel has better properties than import and US workers ensure the chain is up to quality standards and is ready for install. Though working loads and tensile strengths are the same with a domestic chain, the metallurgy that domestic materials support will provide an overall better working life in the long-run.

Flat Bar - These attachments are offered as just a standard steel flat plates/ flights or with UHMW or press-fitted steel tube. The UHMW flights act as the wear strip in the bottom of a conveyor.
HSS Square Tube - These are easily replaceable UHMW or steel tube sleeves that reduce wear, maintenance cost, power consumption, and reduce noise.
Non-standard attachments are made per requested dimensions from the customer.
