Universal Series US/USW
With motor Without motor

Features

1.Long service life
Most US models have a running life of 20,000km with the maximum load capacity applied (10,000km for US6 and 8), which is the highest level of service life in the industry. LM Guide and ball screw running life can also be calculated based on usage conditions.

2.Long-term maintenance-free operation
Thanks to the use of Caged Ball LM Guide model SHW (US8) and model SHS (US12, 16, and 20) in a rectilinear guide, and Lubricator QZ, which supplies just the right amount of lubricant in the ball screw, this series provides long-term maintenance-free operation.
Model SHW is highly resistant to moment load in the Mc direction due to its 4-way equal load design and wide　rail structure.
Model SHS, a global-standard size LM Guide, can accept loads in all directions (radial, reverse radial, and lateral)　due to its 4-way equal load design.

3.High speed
Most units in this series (US8 to USW20) accommodate twice as many types of leads for each ball screw shaft diameter. This reduces processing time and enables the device to operate at high speeds.

4.Smart structure
In most units the standard sensor is incorporated into the actuator, making the actuator highly compact(this does not apply to the US6). For other sensor options, the sensor is installed on the outside of the unit.
US8: 1 sensor (home position); USW12, 16, and 20: 3 sensors (home position and ends).

5.Easy assembly
For the standard unit, both table and base have dowel pin holes, and the base has elongated holes. These facilitate installation and assembly, enabling the unit to be mounted easily. Either top face mounting or lower face mounting can be selected for the base (this applies to US12, 16, and 20 only).

6.Versatile lineup
These units accommodate stroke lengths, specified in 50mm increments, ranging from 100mm to 1,700mm. Many types of ball screw leads are provided as well, enabling customers to select a unit ideally suited to their needs.
