Patented NEMA gearheads are energy-efficient alternatives to conventional "cut gear" speed reducers. Each unit uses a "composite gear" (precision roller chain mounted on a disc to form a pin gear) in cycloidal, differential, and planetary design configurations. Operational features include compact aluminum cases, pin gear construction that permits force transmission in either direction, and gearhead reductions ranging from 3:1 to 595:1.

Zero-backlash bellows and torque-limiting safety couplings are for digital servo drives, spindles, and tools operating at speeds up to 10,000 rpm. The outside conical hubs automatically quick-release when disassembling, resulting in more accurate manufacturing tolerances, improved bearing wear, and reduced downtime. Release set screws are also available.

Clamp-type shaft collars feature a solid flat and square working face that can be modified to function as a component mounting collar, seal, or hardened thrust-bearing race. The Accu-Clamp™ shaft collar combines a non-marring clamping section with a solid working face that is flat and square within 0.001 inch TIR, and can be machined or hardened. Designed to provide a basic platform that can be faced, turned, drilled, and tapped, the device can be provided with a keyway or an O-ring groove, and threaded to create a mounting surface for sprockets, pulleys, and other components.

DEEPGROOVE® tooling for internal grooving consists of a DEEPGROOVE toolholder shank, head, and clamp, and is available for use with 2, 3, and 4-mm DEEPGROOVE inserts. The maximum depth into the bore for the tooling is 3 inches with a minimum bore diameter of 1 inch, and a ½ inch maximum depth of cut. The toolholder shank diameter is 1 inch, and has an elliptical shaped neck for extra strength and rigidity.

SCF Series Sub Micro Drives introduces a set-point control option. For process control applications where regulation of a process variable to a set point is important, the built-in PI regulator reportedly saves cost, space, and set-up time versus using a stand-alone controller to regulate the drive. Applications include pumps, fans, material feed conveyors, and rewind stands.
