Overview

The IMS-V delivers high efficiency vertical motion even for long travels and heavy loads. Using the same industry-proven technology as the IMS linear stages, the IMS-V provides very high performance in a cost-effective package, making them ideal for precision industrial and laboratory applications. With a linear encoder, repeatability is ensured across the full travel. The stage utilizes a self-locking lead screw to keep the load in place and a low-friction nut to minimize wear.

Highest vertical load capacity (400 N) and longest travel range (300 mm)
Self-locking lead screw ensures best position stability even with power off
FEM-optimized aluminum body allows for high stiffness and minimizes bi-metal bending
Proprietary nut design minimizes wear
Direct position feedback provides superior accuracy and repeatability with minimum hysteresis
Recirculating ball bearings offer support for high loads and counteract moment loads

Features

FEM-Optimized Aluminum Body

Similar to the finite element method (FEM) used to optimize the structural design of IMS series DC and stepper motor linear stages, the optimized aluminum body of the IMS-V is designed for extreme stiffness and minimizes bi-metal bending without compromising weight. This results in a light and stable stage whose rigid body reduces deflection under load.

Recirculating Ball Bearings for High Load Capacity

The IMS-V features four-point contact, recirculating ball bearings to provide superior cantilevered loading capacity compared to other vertical stage families. The caged, recirculating ball bearings counteract moment loads and ensure maintenance-free operation.

Direct Position Feedback

Precision position feedback is provided by a linear scale encoder, which contributes to sub-micron MIM and makes the IMS-V less susceptible to hysteresis. The direct read system is impervious to position drift caused by motion-induced heating of the lead screw for improved accuracy and repeatability.

Efficient Drive System

The drive system utilizes a self-locking lead screw with a proprietary, low-friction and wear-resistant nut optimized for carrying high axial loads. Consequently, these features decrease settling time by minimizing oscillation and unwanted motion. Additionally, the self-locking lead screw is not back drivable. This offers the best position stability, and (in contrast to braked ball screw drives) when the stage is within proper loading conditons, its position will not change when power is off.

Metrology Report Included at No Additional Cost

Newport guarantees specification values which are measured and recorded following ASME B5.57 and ISO 230-2 standards. The typical performance values are two times better than the guaranteed specifications.

Right-Angle Bracket

Newport's EQ180 bracket offers convenient and stable mounting of IMS-V stages. Constructed of black anodized aluminum, the bracket also mounts to IMS series DC and stepper motor linear stages to provide stiff multi-axis positioning systems. Please note that IMS300V load capacity is limited to 100 N when used with EQ180 bracket. Contact us for alternative bracket options for larger payload.
