The KK Linear Module is an integrated precision motion unit that combines a ball screw, linear guide, servo motor, and dust-proof structure. Adopting a modular design concept, it can be directly used as the core transmission component of automated equipment to achieve high-precision positioning and reciprocating motion in the linear direction. Through an optimized structural layout, it perfectly integrates the efficiency of screw transmission with the stability of guide rail guidance. Combined with a high-precision grating ruler (optional) for closed-loop control, its positioning accuracy can reach the micron level. Widely used in 3C manufacturing, semiconductor packaging, precision testing, medical equipment and other fields with strict requirements on motion accuracy and response speed, it can greatly shorten the equipment R&D cycle and reduce integration difficulty, serving as a core component for industrial automation upgrades.
Product Advantages
Through an optimized structural layout, it perfectly integrates the efficiency of screw transmission with the stability of guide rail guidance.

High precision & rigidity, stable operation
Adopting an integrated die-cast aluminum base (or cast iron base), internal stress is eliminated through aging treatment, and the parallelism error between the screw and guide rail is ≤0.003mm/m. Combined with a preloaded nut design, axial clearance is effectively eliminated, and the positioning accuracy can reach ±0.005mm, meeting the needs of precision processing and testing.

Modular design, easy integration
Built-in motor, screw, guide rail and protective structure, no need for customers to assemble and debug by themselves, and can be directly installed on equipment via flanges or bolts. Supports multi-module combination (such as X-Y-Z three-axis linkage) to adapt to complex motion trajectory requirements, improving equipment integration efficiency by more than 60%.

High-efficiency transmission, rapid response
The ball screw transmission efficiency is ≥90%, paired with a high-torque servo motor, the acceleration time is ≤0.1s, enabling fast start-stop and high-speed continuous operation. Compared with belt-driven modules, the response speed is increased by 50%, and there is no slippage, ensuring motion consistency.

Comprehensive protection, long service life
The standard version is equipped with an organ-type dust cover and sealing ring to effectively block dust and oil. The IP65 version adopts a fully enclosed structure and can work stably in humid and dusty environments. The built-in long-acting lubrication system extends the maintenance cycle to 6-12 months, and the service life can reach more than 20,000 hours.

Selection & Installation

1
Selection Points
Select the model based on load weight, operating speed, positioning accuracy and stroke requirements - KK40/50 series is preferred for light-load and high-speed scenarios; KK80/100 series is recommended for heavy-load and high-precision scenarios; IP65 protection version with corrosion-resistant accessories is required for humid and dusty environments.

Installation Notes
The mounting surface should be milled with flatness ≤0.02mm/m and roughness Ra≤1.6μm; use M8-M16 high-strength bolts for fastening (specific specifications match the module model), and the torque must meet the product manual requirements (e.g., M10 bolt torque of 40N・m is recommended for KK60 series); when multiple modules are linked, the parallelism of each module should be guaranteed to be ≤0.01mm/m.
