CECON units are available with a disconnect feature that provides physical separation of the input and output shafts. This allows maintenance to be performed on the non-energized driver while the disconnect CECON is locked out in the disconnect position.

•	Designed for high-speed, continuous operation
•	View port allows visual confirmation of disconnect/connect status
•	Full-speed testing of isolated equipment prior to reconnection
•	Operates in adverse atmospheres
•	Reduced downtime
•	Long Service Life
•	Minimum maintenance

TB Wood’s offers a full line of sheaves and drives to meet your specific application requirements.

•	Conventional V-Belt drives
•	Narrow drives (Ultra-V)
•	Light-duty drives (FHP)
•	Synchronous Plus drives
•	QT Power Chain® synchronous belt drives

•	Automatic engagement and disengagement
•	Delayed engagement produces a “no load start”
•	No slippage at full running speed
•	Controlled soft-start acceleration
•	100% efficient at rated speed
•	Standard, spring control, and deep pocket models
•	Protection against shock loads during start-up

The flexibility of Wood’s engineering, foundry and machine shop facilities allows us to design and manufacture special non-standard (made to order) sheaves and pulleys to meet a variety of customer requirements. Sheaves and pulleys up to 108 inches O.D., with any face width can be built to customer designs or can be designed by Wood’s experienced engineers to customer specification.

Sure-Grip® “Quick Detachable” bushings are easy to install
and remove. They are split through flange and taper to provide a true clamp on the shaft that is the equivalent of a shrink fit.

•	6-hole drilling (most sizes) makes installation and removal quick and easy.
•	Keyseat 180° from split.
•	Precise taper (3/4 in. per ft. on diameter) provides proper wedging action.
•	Saw cut through flange and taper (and sometimes cut down into keyway also) to provide a true clamp fit.
•	Cap screws used to secure bushings to sheave and to remove bushing from sheave

Up to 169 kNm;
1,500,000 in.lb.

State-of-the-art design from Bibby Transmissions, the original grid coupling manufacturer. G-Flex/Bibby 2000 Series is an all-metal coupling that provides positive protection against the damaging effects of shock loads and vibration. Aluminum horizontal cover (T10), and
all-steel vertical cover (T20) designs are available. G-Flex tapered grid couplings are an excellent choice where torsional flexibility/vibration damping are primary concerns.

•	Easy to assemble / replace
•	Part-for-part interchangeable with industry standard tapered grid coupling designs
•	Coupling sizes 1020 through 1140 in-stock in a range of standard bore sizes
•	Shot-peened tapered grid flex element for long life

Up to 96 kNm;
850,000 in.lb.

These pin and bush couplings accept parallel, angular and axial misalignment and can provide considerable torsional flexibility.

•	Vertical or horizontal operation
•	80 or 90 shore hardness close fitting flexible elements
•	Steel or cast iron hubs
•	Brake drum or disc available as well as special designs

Available in ratings up to 40,000 HP and output speeds up to 20,000 RPM or higher in ratios up to 9:1. Nuttall Gear's design features include heavy cast iron or welded steel housings for strength and rigidity, dynamically balanced precision double helical gears for uniform load distribution, and oversized split sleeve bearings with labyrinth oil seals to insure reliability.
