Power and Performance for Oil Field Operations
Energy Series™
When Power Counts
High productivity, high speeds, high shock loads, and high cyclic loading in the oil field put great demands on roller chain. Count on the experts at U.S. Tsubaki to deliver Energy Series — the chains you need to keep your operation running smoothly.
Engineered for quality and performance
U.S. Tsubaki builds performance into every Energy Series chain. We start with the highest-quality steel, manufacture all parts to stringent tolerances, and provide the most effective heat-treatment processes to maximize tensile strength and shock load resistance. That means long-lasting chain in the toughest applications.
Stronger pins for longer chain life
Drilling applications put a lot of stress on pins, and pin wear can cause early chain failure. Energy Series pins are made of special materials, precision-ground to ensure accurate fit, and assembled only after our proprietary heat treatment. The result is tough, through-hardened pins that increase fatigue strength and allow the chain to better withstand shock loads.
Ballized holes for smoother contact
Fatigue cracks can start from imperfections in the plate holes. Energy Series chains are manufactured to minimize imperfections. After heat treatment, the pitch holes on the side plates are ball drifted to impart residual compressive stress and create extremely smooth hole surfaces, which maximizes fatigue strength.
Pre-stressed for performance out of the box
All chains are pre-stressed to ensure uniform load distribution and to minimize initial elongation. The result is better operation immediately following installation and throughout the life of the chain.
Pitch-compensated
link plates maintain
maximum strength
Energy Series link plates have wider waists, putting more steel where you need it to handle shock loads. The added plate strength creates a rigid link with less deflection
under load. Center plates are pitch-compensated, creating a contact fit that allows easy cutting and assembly while maximizing chain strength. The plates hold tighter and share the load equally, creating higher fatigue resistance and longer lasting chain.
Building better bushings and rollers that last
Roller and bushing designs play significant parts in chain life. Every Energy Series chain uses solid rollers, which are carefully formed from high-grade steel into optimal roundness and then heat treated and shot peened for toughness and strength. Energy Series features
solid bushings for large sizes and precision-formed bushings for small sizes. Both types of bushings are fabricated to be the roundest in the industry for smooth,
long-lasting operations.
Factory-applied hot-dip lube penetrates deeper
The final manufacturing step before chains are shipped is one of the most important.
U.S. Tsubaki dips each chain in hot lubricant, so it penetrates deeper than typical surface sprays. This special step puts the lube where you need it — deep into the pin and bushing area — to extend the working life of the chain.
