High Precision KK Series Linear Module | Ball Screw Driven Linear Stage for CNC Automation
KK Series High Precision Linear Modules
The KK Series is a family of ball screw driven linear modules that integrate precision ground guide rails and a preloaded nut into a single, compact profile. Available in five frame sizes — KK3001, KK4001, KK6005, KK8010, and KK10020 — the series covers a wide spectrum of automation needs, from micro-positioning in semiconductor inspection to heavy-load transfer in CNC machining centers.
Core Advantages
- Choose from 5 frame sizes – KK3001 through KK10020 match your load and speed requirements without over-specifying.
- Save installation time with an integrated guide-and-screw design that eliminates alignment procedures.
- Maintain positioning accuracy across the entire stroke, supported by a rigid, low-profile extrusion.
- Operate quietly and smoothly with recirculating ball guides and precision-ground screw threads.
- Adapt to diverse automation tasks – from semiconductor inspection to heavy industrial gantries.

Product Overview
Design & Performance Highlights
The KK modules achieve their compact footprint by sharing a common extrusion profile for both the guide rails and the screw support bearings. This eliminates the need for separate rail alignment and reduces the overall stack height, allowing tighter integration into multi-axis systems.
All KK models use preloaded ball nuts to eliminate axial play, with the preload factory-set and sealed to maintain consistency over the module's lifetime. The larger models (KK8010 and KK10020) feature additional reinforcement ribs in the base extrusion to handle moment loads in cantilever or gantry configurations.
Typical Applications
- CNC machining and routing systems
- Industrial robotic arms and gantries
- Laser cutting, welding, and engraving equipment
- Semiconductor wafer inspection and handling
- 3D printing and precision assembly lines
- Automated packaging and material transfer
Customization Options
- Custom stroke lengths (beyond standard ranges per model)
- Motor mounting brackets for specific servo/stepper brands (Mitsubishi, Yaskawa, Panasonic, Delta, Sanyo)
- Integrated limit/home sensor kits (NPN/PNP, magnetic reed, or optical)
- Protective metal covers or flexible bellows for chip/coolant environments
- Vertical orientation brake kits
- Special lubrication options for cleanroom or food-grade applications
Why Choose the KK Series?
For automation engineers, the KK Series offers a practical alternative to building custom linear axes from separate guide and screw components. The factory-pre-aligned assembly removes the risk of misalignment-induced wear and reduces commissioning time from hours to minutes.
Compared to belt-driven modules in the same compact class, the KK's ball screw drive delivers substantially higher thrust at low speeds — essential for applications requiring holding torque or precise incremental moves. The sealed nut and wiper system on the guide rails provide protection against fine dust and particles, extending maintenance intervals in production floor environments.
