This catalog features our US-manufactured lineup with 15mm and 20mm caged ball-type linear guides. Ball screw models suit high-thrust applications; timing belt models excel in high-speed, long-stroke operations up to 3000mm base lenght.
Ball screw type GL-N linear actuators (standard configuration) are eligible for quick ship service with 2-week assembly and delivery. Motor interface options vary according to order quantity.
THK flexibly accommodate customizing requests to your meet needs such as
・Non-standard lengths
・Right/Left Screw Thype
・Custom motor mounting brackets, etc.
Please contact with THK via Chat, local contact, distributors.

Model GL-NFeatures
Lightweight, high rigidity aluminum base with Caged Ball LM Guides has
been utilized for the guide portion. A screw or belt options are
available for the drive system.
In addition, Caged Ball LM Guides
and QZ Lubricator for the Ball Screw has been utilized to provide a
long-term maintenance free linear actuator.
Structure
Ball Screw
Timing Belt
Utilizing Caged Ball LM Guide (SSR, SHS)
-
SSR model:
Due to its 90-degree ball contact structure, is best suited to horizontal applications with relatively low moment loads.
-
SHS model:
It can handle loads from all directions (radial, reverse radial, and horizontal) with its 4-way equal load rating capability.
Drive System
Ball Screw Type
Variety of screw leads can be selected.
| Model number | Ball Screw lead (mm) |
|---|---|
| GL15N | 5, 10, 16, 20, 30 |
| GL20N | 5, 10, 20, 40 |
Note: For wrap-around motor types, three motor directions (left, right and bottom) can be selected. (See page 4 for details.)
Timing Belt Type
Highly rigid timing belt ensures that high speed processes are possible for longer stroke applications than the Ball Screw driven type.
| Model number |
Pitch diameter (mm) |
Slider move distance per pulley rotation (mm) |
|---|---|---|
| GL15N | 35.01 | 35.01×π≒110 |
| GL20N | 38.20 | 38.20×π≒120 |
Note: Because the timing pulley has a large pitch diameter, the use of a reducer is recommended. For details, see pages 18 and 19.
Lightweight and High Rigidity
By using a hollow aluminum extrusion, lightweight and high rigidity is achieved.
| Model number | Geometrical Moment of Inertia | Weight | |
|---|---|---|---|
| lX (mm4) | lY (mm4) | (kg/m) | |
| GL15N | 1.61×105 | 2.47×106 | 4.85 |
| GL20N | 3.15×105 | 4.28×106 | 6.47 * |
* The weight of the SSR model is 6.69kg/m.
GL-N Model also Available with Optional QZ Lubricator
A Caged Ball LM Guide and QZ Lubricator for the Ball Screw have been utilized to ensure a long-term maintenance-free linear actuator.
Ensuring Adaptability with Most Advanced Motors
A large variety of flanges have been engineered so that a wide selection of motor options are available to be used with the GL-N.
Multiple Options Available
Multiple options such as covers, bellows, sensors and cable carriers are available.
Compatible with the Conventional GL Model
Due to the dimensions between the GL models and the GL-N models are
same.
Replacing with the GL-N is easily possible (GL20N).
