The K1 Lubrication System, used for precision ball screws and linear guides, has an oil-impregnated porous olefin seal designed to lubricate the rail or screw while sealing out damaging contaminates. The reportedly long-lasting seal prevents environmental pollution caused by oil, making it suitable for applications such as manufacturing devices in the food, medical equipment, and semiconductor industries.

UniSlide® Assemblies measure absolute travel distance position using an optical encoder for gauging, testing, and alignment. The encoders are available in resolutions of 0.0005, 0.0001, and 0.000005 inch. Travels range from 1 to 84 inches, with stages in four cross-sectional widths, bearing 300 lbs: 2.5-, 4-, 6-, and 9-inches. RS-232C interface, zero reset button, and inch/metric toggle switch are featured in LED Digital Readout.
The DES 70/10 digital servo-amplifier is intended for brushless motor velocity and torque control. It reportedly maintains torque control and smooth velocity, regardless of speed, due to 50 kHz sinusoidal commutation. The 4-quadrant servo-amplifier uses 24 to 70V dc supply voltage, operating at 10A continuous current or 30 A peak current. Measuring 180 × 26 × 103 mm, it is protected against over-current, over-temperature, and short circuit of motor leads.

DualVee guide wheels—made of an inner race, outer race, and heat stabilized 440C stainless steel ball bearings—operate at temperatures up to 500F/260C. A pair of 304 stainless steel shields separate the ball tracks, which are kept in place by a 304 stainless steel retainer. Guide wheels have a radial load capacity up to 574 lbs/wheel. According to the company, guide wheels are intended for antifriction guided motion, high temperature capability, and contaminant resistance.
