Lubrication system
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.

Servo-amplifier
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 x 26 x 103 mm, it is protected against over-current, over-temperature, and short circuit of motor leads.

Guide wheel
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.
