WR106 Chain - Welded Steel Mill Chain

Our welded steel WR106 chain is manufactured to exceed expectations in working life, strength, and quality. The welded steel style chain is one of the most popular types of Engineer Class Chain on the market. This is widely due to its effectively productive offset link design. With an ultra-high tensile strength of 54,400 lbs at a low per foot weight of 7.0 lbs, WR106 chain makes an excellent and efficient use in whichever application it is used in. What makes our WR106 chain different is the use of high-grade steel so the core of the components has great metallurgy. Common applications for WR106 welded steel chain include heavy-duty conveyors, forestry, grain handling, pulp, paper, and sugar processing. This chain is supplied as 10' coils (20 link strands) and is supplied with one heat-treated connecting pin per coil.
WR106 vs WH106 vs WH106HD vs WH106XHD
WR106 and WH106 chain directly interchange with each other dimensionally and are both equally as popular. WH106HD heavy duty chain and WH106XHD extra heavy duty chain dimensionally is the same but with different side-bar thicknesses, WH106HD = +0.125" and WH106XHD = +0.125". However, when taking a closer look there are differences. WR106 does not implement fully heat-treated components like WH106 and WH106XHD chain does, thus it has a much quicker wear life and a lower tensile strength rating. Because of this we primarily recommend WH106 chain for general applications and WH106XHD chain for applications requiring the highest strength 106 chains available.
WR106 tensile strength - 54,400 LBS
WH106 tensile strength - 69,000 LBS (+14,600 LBS)
WH106HD tensile strength - 92,500 LBS (+38,100 LBS)
WH106XHD tensile strength - 122,000 LBS (+67,600 LBS)
Made in USA WR106 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 WR106 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.

WR106 Chain Attachments

WR106 attachments can be supplied onto the chain in any spacing/ configuration needed.
Standard Attachments:

WR106 S1	WR106 Slasher	--	--
WR106 A22	WR106 A22 Slotted	WR106 Log Chair	--
WR106 A Cradle	WR106 B Cradle	WR106 C Cradle	WR106 Special C Cradle

Non-Standard Attachments:

Pusher Attachment	Flat Bar	HSS Square Tube

Pusher Attachment - These are used in trimmer applications, steel mills, and applications for pushing heavy or large products.
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.
