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
HZ RIVETED & COTTERED SERIES CHAIN - HZ series chain has the same dimensions as ANSI-standard heavy series chain
- The "Z" designates through-hardened pins that are utilized for higher working load capacities and additional resistance to fatigue in heavy load applications
