Bibbigard safety element torque limiters incorporate a number of safety element modules of a specific size mounted between two flanges and preset to release at a specified torque value in order to protect the drive system from expensive damage and lost production. They can be used with various types of drive medium many of which are available from Altra Industrial Motion. Bibbigard has been successfully utilized in many different industries where, subject to space availability, the release torque capacity is virtually unlimited.

•	Accurate release torque repeatability
•	Simple fast manual re-engagement
•	Low-cost maintenance
•	Versatile mounting capability
	*Tangential force per module

For high cyclic and general clutching duties. Specially designed for end-shaft mounting onto a bearing supported flywheel or gear wheel.

•	Start/Stop parts have a low inertia which:
	-	Reduces acceleration times and allows more cycles per minute
	-	Reduces heat generated
•	Air applied clutch with full circle friction discs
•	Extremely fast response
•	Available in 1,2,3 or 4 plate designs to suit torque, heat, response and space requirements.
Air connection via rotary union/seal/coupling mounted directly into front of clutch for fastest response time. For dry use only.

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

Wichita's mechanical PTO's are powered by Eaton's Solo™ mechanical 2-plate clutch. Built-in damping springs on the clutch; driven discs and no pilot bearing are some of the standard features that make Wichita's mechanical PTO user friendly when applied in the harsh environment of diesel engines.

Highlights of Wichita's mechanical PTO are:

•	Adjustment free feature automatically adjusts the clutch
•	In-line and side-load bearing carriers
•	30 Lb. handle pull to engage clutch

Fully-crowned gear teeth
provide operational benefits
including maximum
load-carrying capacity with minimum size, maximum
reliability and long life.

•	Both “O” ring and metal seal models are available
•	Strong, rigid floating sleeve
•	Precision-machined identical hubs
•	Positive dust-tight seals

Up to 0.70 kNm;

Sure-Flex is a TB Wood's original! Sure-Flex Couplings utilize a rubber (EPDM or Neoprene) or Hytrel™ thermoplastic flex element (sleeve) to transmit torque and accommodate shaft misalignments. Sure-Flex couplings have exceptional torsional flexibility, and the
4-way flexing action absorbs virtually all types of shock, vibration, misalignment, and
end float. Sure-flex couplings are an excellent choice when low cost, high flexibility, vibration damping, and easy installation are primary concerns.

•	Easy assembly
•	Spacer, bushed hub, and clamping hub designs in stock
•	Flexible design accommodates misalignment and protects equipment
Typical Applications
•	Pumps
•	Fans/Blowers
•	Electric Motors
•	Compressors
•	Mixers
•	Conveyors

Up to 4.50 kNm;
39,500 in.lb.

Dura-flex couplings "split-in-half" element design allows for easy element installation/ replacement without moving connected equipment or disturbing the shaft connection. Spacer design can accommodate a large range of shaft spacing with few parts. Patented design minimizes bond stress for long coupling life. Highly flexible and able to accommodate shaft misalignment while minimizing vibration and preventing damage to connected equipment.

•	Easy to assemble/replace
