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.

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.
