Core shafts and mandrels (air shafts) are used to handle winding reels in the processing of web-fed materials.

Line Drivers

(22 companies)
Line drivers extend the transmission distance between terminals or computers connected along private lines or networks.

Pump Drives

(11 companies)
Pump drives take an input rotational power source and route it to hydraulic pumps via gears or other means. The pumps are mounted on the drive housing.

Trace Line Heaters

(50 companies)
Trace line heaters are flexible, insulated cables that are heated with electricity or re-circulated fluids. They are used to prevent liquids in pipes from freezing, or to reduce heat loss in piping.

Servo Drives

(467 companies)
Servo drives provide electrical drive outputs to servo motors in closed-loop motion control systems where position feedback and corrective signals optimize position and speed accuracy.
Drive rollers and idler rollers convey materials along a belt or within an assembly. Drive rollers are powered by electric motors, while idler rollers are linked in a transmission or unpowered.

Line/Load Reactors

(51 companies)
Line and load reactors are current-limiting, inductive devices used to remove distortion and filter power.

Wheel and Track Drives

(13 companies)
Wheel and track drives are a gearbox, motor and brake assembly which power wheeled or tracked vehicles. Motors can be either electric or hydraulically powered.
Shaft-hub locking devices frictionally clamp gears, pulleys, flywheels, and other components to a shaft without the need for threads or keys.

Rack and Pinion Drives

(28 companies)
Rack and pinion drives use a rotational motor to affect linear motion via a rack and pinion combination. They are used frequently in long-travel applications, such as machine tool table positioning, that require high stiffness and accuracy.

Washers

(1,216 companies)
Washers are disks of metal or non-metallic material placed beneath a nut, an axle bearing, or a joint, to relieve friction, prevent leakage, isolate, prevent loosening, or distribute pressure.

AC Motor Drives

(842 companies)
AC motor drives interface controllers to AC motors. They match the control signals (voltage and power levels) as well as the signal type (analog or digital). They also provide power conversion, amplification, and the sequencing of waveform signals.

Top Drives

(22 companies)
Top drives are suspended mechanical devices that provide torque to the drill string and serve as an alternative to the use of a Kelly drive or rotary table.

Hard Drives

(460 companies)
Hard drives are integral, non-volatile, electronic data storage units inside computers. Traditionally, hard drives were hard-wired into computers. Removeable hard disks and drives are also available.
PCMCIA hard drive cards provide high storage capacities for notebook and palmtop computers, personal digital assistants (PDAs), mobile systems, and PCMIA-equipped computers.
