Achieving labor reduction through modularization and compacting the movable parts of the device.
The THK Electric Actuator Compact Series KR is widely adopted in various industries such as machine tool, automotive, and electronic components for many applications including transportation, inspection, and assembly. Through modularization, the number of parts is reduced by about one-third, and design man-hours are reduced by approximately 57%, while assembly man-hours are cut by about half. By leveraging these features, it enables size reduction for adopted work hole processing machines and pallet changers, thereby shortening the lead time to complete the equipment. Additionally, the related links provide a wealth of technical information, including detailed product descriptions, product catalogs, user manuals, 2D and 3D CAD files, selection materials, technical calculation programs, specifications, and dimension drawings. Please take a look at these as well.

basic information
● Four-directional equal load The ball rows are arranged at a contact angle of 45° to ensure that they have the same rated load against loads acting in four directions (radial, reverse radial, and lateral) on the inner block, allowing for use in any posture. ● High precision Due to the four-row circular arc groove, which moves lightly even under preload, the linear guide provides a gapless and highly rigid guidance. Additionally, changes in friction resistance due to load fluctuations are minimized, enabling high-precision feeding. ● High rigidity The adoption of a U-shaped cross-section for the outer rail has improved rigidity against moments and torsion.
