The Uni-Guide family utilizes the proven plane bearing technology of Simplicity®, which allows the carriage to glide smoothly along the slide. The proprietary Frelon liner ensures safe travel over dirt, dust, grime and other particulates without damaging the rail or carriage. Maintenance-free and self-lubricating, the Uni-Guide products require no additional grease or oil and thrive in applications where contamination must be prevented: food processing, lab automation and medical equipment.

Comprised of a simple, two-piece rail and carriage assembly, Uni-Guide products facilitate quick system integration without the mounting components and alignment necessitated by other linear slide products. These competing products, such as re-circulating ball or polymer insert linear slides, use assemblies with multiple rails and components, and require painstaking alignment to ensure uniform parallelism across all assembled rails and carriages. The Uni-Guide family promotes ease of installation by machining two parallel rails in one profile. The one-piece carriage design also simplifies assembly by directly fitting onto the rail without fasteners—saving the end user on cost and reducing tolerance stack-up.

To ensure precision tolerances are maintained, the rail and carriage of the Low Profile Uni-Guide are machined by our patent pending SIMO® process. SIMO uses a synchronized tooling system to mill all critical edges concurrently—creating consistently tight tolerances that hold within ±0.001’’ (0.025 mm) for assured high accuracy travel.

SIMO® also produces specially angled edges along the LP Uni-Guide rail to support clean wash-down without chemical pooling. The angled edges also work with the overall design of the LP Uni-Guide to prevent any contamination from accumulating in the assembly. This makes the LP Uni-Guide a perfect design selection for food processing tasks.

Available with hand-brakes for quick manual adjustment and positioning, extended carriages for enhanced load dispersion and standard tap holes for mounting ease, the Low-Profile Uni-Guide is a versatile product that can be tailored to meet the customers’ needs.

Ultra-Smooth, Precise Motion
Aerotech’s high-power, cog-free linear motors drive the PRO LM series. The non-magnetic forcer coil provides high force with zero cogging for ultra-smooth velocity and position control. This zero-cogging design is ideal for applications requiring outstanding contour accuracy and smooth velocity profiling. Aerotech’s linear motor stages have zero backlash, no windup, and outstanding system responsiveness. The magnetic field of the linear motor is totally self-contained within the U-channel design, making these stages well-suited for high-performance applications that cannot tolerate the stray magnetic fields generated by flat motor magnet tracks.

Noncontact linear encoders with micron-level repeatabilities are standard on all PRO LM series stages. Either a line-driver output or amplified sine-wave output encoder is available. The optional HALAR factory calibration further increases the standard accuracy and repeatability.

Construction Features
Sealed linear motion guide bearings with integral wipers are incorporated to provide excellent payload capacity and long life. Both the metal waycover and tabletop are treated with a hardcoat that is scratch-resistant and provides outstanding protection in the harshest applications, while the tabletop utilizes stainless steel Helicoil™ inserts to protect mounting holes against thread wear. Several tabletop options are available for metric or English mounting, as well as for direct interface with our popular ADRS, ADRT, and AGR rotary stages. In addition, configurable cable management options are available for single- or multi-axis systems.
