By incorporating an LM Guide within its rectilinear guide, the ES provides both compactness and reliability.
Compact and reliable
The use of LM Guides reduces the number of components required, making the ES available at a reasonable cost.
Reasonably priced
The ES incorporates the model SRS LM Guide, equipped with ball retainers, as well as Lubricator QZ, for optimal
ball-screw lubrication. The combined effect provides for long-term maintenance-free operation.
Long-term maintenance-free operation
The service life of the LM Guide and ball screw can be calculated based on usage conditions.
Contact THK for details.

When 0 is selected, a coupling is not provided
for motor direct coupled specification. Timing
pulley and timing belt are provided for motor
wrap configuration. When 1 is selected, THK
will prepare a motor and install it.
For ES3, ES3R, EC3, EC3R and
EC3H, have ball screw lead of
6mm only.

under the following conditions: 5,000km running life, single-direction load, 0.3G
horizontal or vertical, 150mm stroke.
×2Value when THK control device is used. Actual load mass should be determined
based on the specifications of the motor used. See "Reference Materials for Selecting
ES" in P.39.
