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

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

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.

The exclusive use of the involute helicoid thread form on the worm and gear provides for high efficiencies and long service
life. The hardened, ground and polished alloy steel worm develops a smooth, work hardened surface on the bronze gear. For this reason, the worm gears wear in and improve with prolonged service while other gears are wearing out.

•	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

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.

This line of electrically-released, dynamic, spring-set brakes (ERD) offers a high-performance, cost-effective solution for power-off load holding applications. With the removal of electrical power, whether accidentally or intentionally, they may be applied in any dry environment where a severe and dependable braking action is required. Torque range from 4 to 220 lb.ft.
