Linear guide

Featuring 300 Series stainless steel construction for corrosion resistance, the HSR-M-2A LM guide has four rows of load-carrying balls between the rail and the block. On each side of the rail, two of the grooves are arranged in tiers, permitting the balls to contact the block at a 45 degree angle. A self-adjusting capability lets the guide maintain accuracy.

Roll feed

The Zig-Zag Roll Feed moves material forward and back-and-forth, rather than just forward, to maximize material usage and cut waste. Features include a brushless ac servo motor, belt drive, linear guide, aircraft-grade aluminum feed body, and permanently lubricated bearings. The unit is programmable for diagonal and forward bridge amount, pattern angle and offset, number of lanes (up to 50), lane shift, acceleration, and speed (up to 600 strokes/minute).

Controller

Measuring 3.68x1.815x0.35 inches, the RTC-3000 stand-alone controller-amplifier can operate most small brush and brushless dc servo motors. The controller includes an amplifier, logic power supplies, and program interpreter with 32 kbits program memory and 32 kbits data storage. As many as 120 controllers can work together on an RS-485 network; other communications options are over RS-232 or between the controller and a host or PLC.
