•	Fewer sizes to cover a full range of applications
•	Reduced spare parts inventory
•	Lower total cost of ownership
•	Special designs avaiable for higher-torque applications

•	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

Complete line of spur, helical, miter, bevel, worms and worm gears.

•	Thousands of gears are available for immediate shipment
•	Custom gears can be designed and manufactured
•	All gears are manufactured to the strictest standards for the highest quality product available

Wichita's Air PTO is powered by our heavy-duty Standard Vent clutch. With large friction areas for high energy starts and an air actuated clutch for remote or automatic control of the PTO.
The air actuated PTO is ideal for your application because:

•	The bearing supported shaft eliminates sideload on the crankshaft
•	The high speed airtube not affected by centrifugal force
•	There are no o-rings or diaphragms to wear out
•	14" and 18" 1, 2 & 3 plate clutches available

Boston Gear's 800 Series contains a focused selection of compact, heavy duty helical gear drives that offer long-life performance and simplified maintenance. The 800
Series provides a functional
interchange for SEW Eurodrive
and other European manufacturers' helical gear drives, making it uniquely practical for replacement
applications.

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

The Twiflex centrifugal clutch coupling is designed to provide load free starts and smooth acceleration. Ideal for engine drives.

•	Loads are smoothly accelerated giving soft start
•	Reduces shock on shafts and gearing
•	Engine starts and idle free of load
•	Serves as automatic throttle controlled clutch
•	Eliminates shock loads
•	Prevents engine stall under sudden overload
•	Prevents engine reverse swing when coming to rest
•	Limits vibratory torques to safe level
•	Combines advantages of an efficient flexible coupling.
•	100% efficiency saves fuel.
•	Long trouble-free life with no routine maintenance.

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

These torsionally stiff, light weight couplings are capable of transmitting high torques at high speeds while accepting significant levels of angular, radial, and axial misalignment. They are easy to install, suitable for hostile environments, require no lubrication and feature a high torque to weight ratio. Specific designs are available which meet the customer’s exact requirements. Standard units are compliant with API 671 (American Petroleum Institute) and ATEX 94/9/EC.

•	No maintenance
•	Standard and reduced moment designs available
•	Capable of being torsionally tuned to suit specific machinery requirements

Unique diaphragm design permits high-torque density and low weight. Designed for years of dependable, low-maintenance performance.

•	Multiple, separated, convoluted diaphragms allow greatest design flexibilty for most demanding applications
•	API-671 compliant
•	Best for high axial travel requirments

Form-Flex metal disc couplings consist of two hubs, a spacer and two high strength carbon or stainless steel flexible discs. Modified and special designs are commonly supplied to meet specific application conditions. Available in carbon steel, stainless steel or with corrosion resistant coatings.

•	No maintenance
•	Zero backlash
•	Close couple, spacer and floating shaft designs available
•	Easy interchangeability
