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.

These units combine the best of both chain and belt drives, providing positive power transmission and accurate speeds while requiring little maintenance. Load capacities scale up to 1200 HP at 1750 RPM.

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

Up to 8.20 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

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
•	High Misalignment ratings
•	No maintenance/lubrication
•	Part-for-Part interchangeable with industry standard design
•	In-stock versatile spacer design can accommodate many configurations with few parts
