Bearings
Fiberglide(R) self-lubricating bearings offer load capacities of 40,000 psi for static loads and 20,000 psi for dynamic load applications. Bearings also provide reportedly long life due to its heavy-duty construction, making them suitable for construction, agriculture, trucking, material handling, and power transmission. Lining the bearings are woven PTFE and polyester fibers, bonded to a steel backing, reducing noise, vibration, and rattling.

Wedge table
The ZP200 8-inch square moving wedge table is made for exact positioning and high speed vertical lifting. Offering up to 375 lb payloads in a one-inch travel path, its unobstructed mounting surface also reportedly positions within plus or minus 1 micron. Recirculating square rail bearings within the wedge design maintain X-Y integrity while allowing for high dynamic vertical translation. The ball-screw drive has selectable leads of 5, 10, or 20 mm that may be matched to specific speed/resolution needs.

Gearboxes
The GTM Planetary Gearboxes, used in factory automation applications, is reportedly rated up to 10 dB less than other gearboxes, due to its small internal cavity designed to reduce noise. A large taper bearing, for longer life and higher radial and axial loads, serves as a pump that reduces oil amounts in horizontal, vertical, or angled applications; hence, the gearboxes lower inventory and create less friction and heat.

Amplifier
The 4-Q Linear Servo Controller 30/2 is the company's latest servo amplifier made to drive low power permanent magnet dc-motors up to 50W. The linear power stage offers zero electromagnetic emission and smoothly runs the motors with any feedback system. A DIP switch allows users to choose the operating mode from IxR compensation, current control, voltage regulation, and encoder- and dc-tacho feedback.
