IMS Series High-Performance Long-Travel Linear Stages

Product catalog summary

Overview: The document provides technical specifications and details for the IMS Series High-Performance Long-Travel Linear Stages, designed for precision industrial and laboratory applications. These stages offer high stiffness and are optimized to minimize thermal bending effects.

Specifications:

Material: Extruded Aluminum
Bearings: Double-row recirculating ball bearings with caged balls
Drive Mechanism: Backlash-free ball screw with a 5 mm pitch
Feedback: Rotary encoder with 4,000 pts/rev, and linear scale with 0.1 µm resolution for CCHA versions
Limit Switches: Optical
Motor Options: DC servo motor or 2-phase stepper motor
Cable: 5 m long motor cable included

Performance:

Travel Range: 300 to 600 mm
Resolution: 1.25 µm for PP and CC, 0.1 µm for CCHA
Repeatability: 0.7 to 1.25 µm for PP and CC, 0.2 to 0.5 µm for CCHA
Maximum Speed: 100 to 200 mm/s
MTBF: 20,000 hours

Load Characteristics:

Normal centered load capacity: 600 N
Axial load capacity: <30 N
Compliance in roll, pitch, and yaw: 1 µrad/N.m, 0.2 µrad/N.m, 1 µrad/N.m respectively

Ordering Information: Various models are available with different travel lengths (300 mm to 600 mm) and motor types (DC motor, DC motor with linear encoder, stepper motor).

Design Details: The IMS stages feature a robust design with a protective cover to prevent damage and contamination. They include a motor-end mounted origin for repeatable initialization and elastomeric end-of-run dampers for smooth emergency braking.

Additional Components: The EQ180 bracket allows for vertical configuration mounting, and recommended motion controllers include XPS and ESP300.

The IMS stage features a robust design and high performance but without the high cost. The IMS is a cost-effective solution for precision industrial and laboratory applications. Using the same industry-proven technology as the ILS Series, the IMS Series features an FEM optimized, aluminum extruded body. While high in stiffness, the bending effect caused by different thermal expansion coefficients of the aluminum body and the steel rails is also minimized. Smooth running recirculating ball bearing slides with ball separators provide accurate linear motion and avoid ball cage migration found on linear ball bearings or crossed roller bearings. A high stiffness, backlash-free and efficient 5 mm pitch ball screw ensures rapid motion with fast step and settling times, minimizes heating, thereby extending the stage life. Position measurements are read on a 4000 pts/rev. rotary encoder, mounted directly on the ball screw to avoid screw/coupling errors. For more demanding precision positioning requirements, the IMS-CCHA versions are available with a highly interpolated linear scale providing 0.1 ìm resolution feedback. The upper rigid cover prevents damage to the drive train and protects it from dust, debris and other pollutants. IMS stages also feature a motor-end mounted origin for repeatable initialization, limit switches to prevent over travel, and elastomeric end-of-run dampers for smooth emergency braking. Use EQ180 bracket to mount another IMS or RV (see page 814) stage in a vertical configuration. Two IMS stages and one EQ180 in an XZ configuration. An RV160 (see page 814) vertically mounted with an EQ180 to an IMS stage.
