New Product: Low-Profile Linear-Motor Stage

Manufactured from high-strength aluminum, the Model LT190-EDLM linear stage is 50-mm high and driven by an ironless-core linear motor with travels of 150 to 500 mm.

Typical speed is 1 m/sec with acceleration of several gs.

The stage’s design allows two units to mount together directly without an additional interface plate, creating a low-profile XY configuration.

Features include preloaded large cross-roller bearings for high stiffness and smooth motion; cageassist mechanism that prevents cage migration and ensures reliable operation under high accelerations and speeds of the linear-motor drive; and a sealed design with a metal way cover instead of accordion- type bellows, thus eliminating particle generation.

Three linear scale options based on the resolution requirement (20 nm to 6.25 picometers) are available.
