FAQs of THK KR Series Linear Slide Actuator:

Q: How does the THK KR Series Actuator achieve its high positioning accuracy?

A: The KR Series uses a precision-rolled or ground ball screw drive integrated with a linear motion guide (LM Guide block), delivering high-precision movement with repeatability up to 0.003 mm and tolerance of 0.01 mm. The hardened steel components, precision assembly, and tightly sealed structure ensure consistent, reliable accuracy.

Q: What mounting orientations are supported and how does that benefit installation?

A: The actuator can be mounted in horizontal, vertical, or wall orientations, offering flexibility to adapt to various machine layouts and space constraints. This enables users to optimize equipment design and integrate the actuator easily into existing automation systems.

Q: What applications are best suited for the KR Series Linear Slide Actuator?

A: This actuator excels in precise linear motion tasks for CNC machines, automated assembly lines, semiconductor manufacturing, and broader industrial automation. Its high-speed capability, load transfer capacity, and corrosion resistance make it ideal for demanding environments requiring consistent performance.

Q: How is maintenance handled, and what is the process for lubrication?

A: Maintenance is simplified by the actuators integral lubrication port, which allows for scheduled grease replenishment without disassembling the unit. The sealed body is pre-filled with long-life grease, minimizing the interval and effort of routine maintenance.

Q: Which motors are compatible with the KR Series, and how can they be customized?

A: The actuator is compatible with both servo and stepper motors. Customizable coupling options are available to match a range of motor brands and models, ensuring seamless integration into different motion control systems.

Q: When should dust-proof seal options be considered?

A: Dust-proof seal options are recommended for applications in contaminated or harsh environments, such as machining, assembly, or electronic production lines, where particles may impact performance or longevity. The seals help protect internal components and extend the actuators operational life.
