UMR High Load, Single-Row Ball Bearing Steel Linear Stages

UMR single-row ball bearing linear stages feature a robust steel construction and single-row ball bearings that provide excellent, smooth, linear travel while also capable of carrying high loads. The moving carriage is preloaded by two springs, ensuring constant contact with the micrometer and backlash-free motion.

Single axis, single-row ball-bearing stages
Low-profile steel construction for high stability and rigidity
400 N centered load capacity
BM micrometers are recommended

Specifications

Features

Low Profile, A Wide Variety of Sizes

UMR Series Linear Stages are offered with a variety of translation ranges from 0.2 in (5 mm) all the way to 3.15 in (80 mm). UMR12 stages feature single-row ball bearings and are ideal for applications with large vertical load capacity (+Cx) when mounted in vertical orientation. Similar stages of smaller footprint (UMR3, UMR5 and UMR8) feature double-row ball bearings for higher centered load capacity (Cz) in a horizontal configuration.

MVN Vertical Stage Compatibility

UMR stages are compatible with MVN Series Vertical Stages allowing you to build XZ or XYZ stage stacks with a horizontal oriented mounting platform.

A MVN50 vertical stage is shown on top of a UMR5.25 linear stage.

UTR Rotation Stage Compatibility

UMR linear stages are compatible with UTR Series Rotation Stages allowing you to built X or XY stage stacks with a rotatable mounting platform.

A UTR80 rotation stage is shown mounted on top of UMR8.25 linear stage.

XYZ Configurations

Abundant tapped hole patterns on these stages are included to provide the most options for mounting components on the stage mounting surface. Two stages can be easily stacked to provide XY translation (except the UMR5.5). Z configuration can be assembled using the EQ Series Angle Brackets.

Two XYZ configurations of (3) UMR5.25 linear stages with EQ50 angle brackets are shown. Note: In the vertical orientation with the actuator pointed up, the stage's vertical axial load capacity is reduced.

Adjustable System

We offer Adjustable Right Angle Brackets which allow one arm of an angle bracket to vary in length. This can be useful in adjusting the center of rotation of a UTR rotation stage mounted orthogonal to a UMR stage. It is also beneficial to simply adjust the length of one arm of a UMR stage mounted orthogonal to another UMR stage.

Compatible Actuators and Mounting Accessories

Actuators for UMR stages are not included. The stages can achieve 1 µm sensitivity when directly used with BM series standard micrometer heads or 0.1 µm sensitivity with LTA-HS motorized actuator which requires ADAPT-BM25-375 adapter. The travel of the stage is limited by either the travel range of the stage's bearing or that of the actuator, whichever is shorter.

The carriage of UMR stages can be locked by a carriage lock that mounts in the stage body opposite the actuator. Two are required for fixed positioning. Fixed positioning kits are available for select models.

Brackets and bases are available for creating multi-axis configurations of UMR stages. PBN series steel base plates are used to connect stages with bottom-surface mounting holes to support structures that are inaccessible from below, such as breadboards and optical tables. EQ series angle brackets are made with an open-corner design to allow more mounting space and easier access to adjustments. They are offered in exterior (-E) and interior (-I) versions for building XZ and XYZ motion control in flexible configurations. Adjustable angle brackets are also available.
