Micro-Positioning Stages

LM76 (East Longmeadow, MA) offers micro-positioning stages available in travel lengths from 10 mm to 200 mm. The Micro Stage linear positioning stages are available with 6-mm anti-backlash lead screws or 4-mm lead ball screws. They are suitable for pick-and-place, assembly, sampling, testing, and robotics. The Lead Screw Micro Stage linear positioning stages are available in three travel lengths: 10 mm, 30 mm, and 40 mm. Features include 0.03-mm repeatability, 0.03-mm/full step resolution, and maximum speeds of 50, 80, and 100 mm/sec. The maximum load for all lead screw stages is 4.9 N.

Direct-Drive Frameless Motors

The ULT Series of direct-drive frameless motors from Applimotion (Loomis, CA) is available in sizes down to 27 mm in diameter with axial length to 8 mm and up to a 20-mm through hole. They operate from traditional three-phase trapezoidal or sinusoidal motor controllers ranging from 12 to 320 volts DC. They can achieve speeds to 10,000 rpm, which may be useful in some scanning applications. Hall devices and cable/connector options are available. ULT motors are suitable for applications needing direct-drive low-profile motors such as optics applications and direct-drive rotary table systems. The ULT motors can be used for precision positioning with the user of a high-resolution encoder or for continuous scanning in medical devices, computer component manufacturing, or optical inspection.

Flexured Couplings

Helical Products (Santa Maria, CA) offers miniature couplings, u-joints, and machined springs with integrated attachment components. The line includes couplings with an unlimited variety of customized ends. All of these products utilize the HELI-CAL® Flexure. The configuration of attachments can vary from plain bore to pinion gear. These flexured couplings and u-joints are backlash-free and provide constant velocity rotation regardless of misalignment. With proper attachment, the devices may minimize assembly production time, and reduce the total number of parts purchased, inventoried, or assembled.

Linear Actuators

Haydon Switch & Instrument (Waterbury, CT) has added the size 14 hybrid to its line of linear actuators. The devices are available with a 0.9-degree step angle and come in all four designs: captive, non-captive, external linear, and linear rotary. Combined with a stainless steel lead screw, the linear actuator provides positioning and motion. The step angle allows for a full-step linear movement of 1.6 microns.

Pressure-Compensated Flow Control Valve

Beswick Engineering (Greenland, NH) has released the PCFCD-1N1, an ultra-miniature pressure-compensated flow control valve with low-friction diaphragm. The device is designed to maintain a constant flow rate, which the customer can adjust, regardless of upstream or downstream pressure variations. It works with incompressible fluids and gasses, but is primarily intended for the control of liquids. The pressure regulation is accomplished with a low-friction diaphragm mechanism.

Shaft Grounding Ring

The AEGIS SGR™ Conductive MicroFiber™ Shaft Grounding Ring from Electro Static Technology (Mechanic Falls, ME) is suitable for predictive maintenance programs on VFD-controlled AC and DC motors. By protecting bearings from electrical damage, the SGR may extend motor life by preventing bearing noise, downtime, and motor repairs and replacements. Preventing shaft current damage, the AEGIS SGR provides predictive/ preventative maintenance programs for motor repair shops, maintenance contractors, HVAC service contractors, and in-house maintenance departments. The SGR’s conductive microfibers work with no friction or wear, are unaffected by dirt and grease, and last for the life of the motor, regardless of the RPM. The SGR can be mounted on any NEMA or IEC motor and provides clearance for motors with shaft shoulders, slingers, bearing caps, or end-bell protrusions.
