Single Axis Stage IMTEK - KK Modules
A Single Axis Stage, often called a linear module, is a machine part that moves an object back and forth in a straight line. The KK module is special because it uses a U-shaped outer rail. Inside this rail, a ball screw rotates to move a slide block. Because the guide and the screw are integrated, the whole unit is very compact. You get high rigidity without the bulk of traditional systems. This design is perfect for projects where every millimeter of space counts.

Basic Knowledge of KK Type
The Mechanics of the U-Rail Design
When you look at the KK type single axis stage, you will notice the U-shaped steel track. This is not just for looks. The U-shape acts as both the frame and the guide rail. It keeps the ball screw centered and protects the internal parts from dust. Because the rail is made of high-quality steel, it does not bend under heavy loads. You can mount it directly to your machine base with a few bolts. This simplicity reduces the chance of errors during assembly.
Internal Components and Materials
Inside the module, you will find a precision ball screw and a carriage with recirculating balls. We use hardened steel for the raceways to ensure a long life. The balls move smoothly through the carriage to reduce friction. You will find that the movement is quiet and steady, even at high speeds. We often use C3 grade ball screws to ensure the highest level of positioning accuracy. This level of quality means your machine will stay accurate for millions of cycles.

Key Features
Space-Saving Modular Design
In modern factories, floor space is expensive. You need machines that do more in less room. The KK type is much thinner than a standard guide and screw setup. Because the motor is mounted to the end of the module, the whole footprint is narrow. You can stack multiple stages to create X-Y or X-Y-Z systems easily. This modularity allows you to build complex robots without needing a massive frame.
High Rigidity and Heavy Load Capacity
Rigidity is the most important factor in precision motion. If your stage flexes, your parts will be out of spec. The KK stage uses a wide track and multiple contact points for the balls. This allows the carriage to carry heavy weights while moving fast. Even if you apply force from different angles, the slide block stays on track. You can rely on this stability for tasks like laser cutting or heavy-duty drilling where vibrations must be kept to a minimum.
Common Applications
- In Industry 4.0
- Medical and Laboratory Automation
- Semiconductor and Electronics Assembly
You will see the KK series in almost every smart factory today. Because they are so versatile, they fit into many different roles. They are the backbone of many “pick and place” machines. These machines grab a part and move it to a new spot with high speed. If the stage is not fast and accurate, the whole assembly line slows down. With the KK type single axisstage, you can push your machine to its limits while knowing the parts will land exactly where they should.
Medical labs use the KK series to move test tubes and liquid dispensers. In these jobs, cleanliness and quiet operation are key. The integrated covers on our modules keep the grease inside and the dust out. You can run these stages next to sensitive sensors without worrying about electrical noise or physical vibrations. They help doctors and scientists get faster results by automating the boring work of moving samples.
In the world of electronics, parts are tiny and fragile. You need a stage that moves without shaking. The KK stage provides the smooth motion required for soldering chips or inspecting circuit boards. Because it is compact, it fits inside the small vacuum chambers used in chip making. You can count on the precision grade of these stages to hit the same spot within a few microns every single time.
Installation and Maintenance Tips
You want your equipment to last a long time. The best way to do this is to follow a simple maintenance plan. Even though the KK type single axis stage is very tough, it still needs a little care. You should check the mounting bolts once a month to make sure they are tight. If the bolts are loose, the stage might vibrate, which will ruin your accuracy. You should also keep the rail clean. If dust gets into the tracks, it acts like sandpaper and wears down the metal.
Proper Lubrication Procedures
Grease is the lifeblood of your linear stage. It creates a thin film between the balls and the track. This film stops the metal from touching metal, which prevents heat and wear. To lubricate your KK stage, move the carriage to one end. Apply a small amount of grease through the nipple. Then, move the carriage back and forth a few times. This spreads the grease evenly. Do not use too much grease, as it can catch dust and turn into a sticky mess.
Environmental Considerations
Where you put your machine matters. If you work in a wood shop, you will have a lot of sawdust. In this case, you should use an aluminum cover or a “bellows” to protect the stage. If you work in a wet environment, you might need a stainless steel version to prevent rust. We design our stages to work in temperatures between 0 and 80 degrees Celsius. If your factory is hotter or colder, please let us know so we can give you special parts.
RESOURCE
The KK Series is an integrated module consisting of a U-shaped steel outer rail, a precision ball screw, and a specialized slide block (carriage). It combines the functions of a linear guide and a ball screw into a single, compact unit.
The U-rail serves as both the structural frame and the guide track. This dual-purpose design provides high rigidity against radial and lateral loads while significantly reducing the overall height and width of the module, saving valuable machine space.
Yes, you can. You can mount it horizontally, vertically, or even upside down. However, when you mount it vertically, you must ensure your motor has a brake. This prevents the carriage from falling down if the power goes out. The internal guide system is designed to handle loads from all directions equally.
The module should be lubricated through the grease nipple located on the slide block. We recommend using a lithium-based soap grease. The frequency depends on usage, but a general rule is to re-grease every 3 to 6 months or every 100km of travel.
The lead is the distance the carriage moves with one full turn of the screw. For a KK60, common leads are 5mm, 10mm, or 20mm. If you want high speed, pick a 20mm lead. If you want more pushing power and better resolution, pick a 5mm lead. You should match the lead to your specific speed requirements.
The “Lead” is the distance the carriage moves in one revolution. A higher lead (e.g., 20mm) allows for higher travel speeds, while a lower lead (e.g., 5mm) provides higher thrust force and better positioning resolution.
Yes. To protect the internal ball screw and raceways from dust and debris, we offer both aluminum covers and flexible bellows as optional accessories. These are highly recommended for woodworking or metal-cutting environments.
The life of the stage depends on the load and the speed. We calculate the “rated life” in kilometers. For a typical application, a well-maintained KK module can travel over 10,000 kilometers before showing signs of wear. Following our lubrication guide is the best way to reach this goal.
