Product Description
OIL FIELD ROLLER CHAIN (A.P.I.)
Ballized pin-plate, middle-bar and bushing-plate holes made to precision tolerances provide increased bearing area and press fits, improving fatigue life and working loads
Wide-waisted link plates are manufactured with maximized ball heights from special alloy steels for added strength. The wide link plate profile improves stress distribution, leading to improved fatigue resistance and enhanced performance
A hardened Sheppards hook cotter pin is deployed on chain sizes 60 ~ 180 and provides greater link-plate support and up to twice the shear strength of conventional short split cotters. The easily installed hardened hook cotter pin is designed to retain its position in high-vibration applications without coming loose
T-pin cotters used on sizes 200, 264, and 240 oil field chain. High-shear T-pins are designed to resist corrosion and retain position in the most extreme applications
The solid roller allows for smooth rotation on the bushing, reducing the impact load as the chain engages the sprocket tooth
Our chain is preloaded to 50 percent of minimum ultimate tensile strength (MUTS), which is especially important for applications involving fixed center-to-center sprockets without take-ups. Applications can withstand shock loads up to 50 percent of the chains MUTS without premature elongation
After final assembly, Timken hot-dips the roller chain in a special lubricant. This process ensures that all the load-bearing surfaces are initially protected from metal-to-metal contact, improving the wear life of the chain
Cut-to-length chain available
Other corrosion resistant finishes for components are available for the Oil Field chain upon request
Offsets are NOT suggested for Oil Field chains
Size 264 chain provides greater tensile strength/working load utilizing larger diameter pin and replaces 200H chain
CONNECTING LINKS
Standard connecting links are used when roller chain is operating under normal conditions
Spring-clip style connecting links are used for sizes 60H and smaller denoted by "S/C CO LINK"
Sizes 80 ~ 180H typically use a single special hardened "Sheppards" hook cotter pin denoted by "CT CO LINK SH"
Traditionl dual split cottered key connector links are also available in select chain sizes denoted by "SPL END CK"
Coated T-pins are used on chain sizes 200, 240 and 264 denoted by "CT CO LINK"
For severe applications, press fit connecting links are suggested denoted by "PF CO LINK"
