Actuator includes optic linear encoder and linear motor.
Press Release Summary:
Type KLM features direct drive and fully closed control, resulting in positioning accuracy of 10/500 mm µm and positioning repeatability of ±0.3 µm. Unit operates at speeds up to 2.0 m/sec with accelerations reaching 4.7 g. Caged Technology employs synthetic resin cage with curvature that cradles each ball and separates it from next ball. Spaces between rolling elements retain grease and act as lubrication system for maintenance-free operation.

THK Introduces High Accuracy, High-Speed Type KLM Actuator with Linear Motor
Schaumburg, IL - THK's Type KLM Actuator achieves extreme accuracy through the incorporation of an optic linear encoder and linear motor. Direct drive and fully closed control results in positioning accuracy of 10/500 mm µm and positioning repeatability of +/- 0.3 µm. The Type KLM obtains these accuracies while operating at speeds of up to 2.0 m/sec., and with accelerations reaching 4.7 G.
The KLM is designed for high speed, high accuracy and long-term maintenance free operation. Based on the THK successful SKR actuator, the KLM is designed with a linear motor. Both rigid and compact, Type KLM is interchangeable with THK's Type SKR Actuator. A THK Caged Ball(TM) LM Guide offers the Type KLM high accuracy and high-speed capability. Patented THK Caged Technology employs a synthetic resin cage with a patented curvature that cradles each ball and separates it from the next. The spaces between the rolling elements retain grease and act as a lubrication system for long-term, maintenance-free operation. Caged Technology benefits also include smooth movement, low noise and low dust generation.
The overwhelming success of THK's caged technology has propelled the expansion of this superior technology throughout the product line. THK is also expanding their product offering to include larger and smaller sizes as well as new materials and technology to achieve superior results in the most demanding applications.
