Commonly installed in CNC machinery, industrial automation systems, semiconductor equipment, packaging machines, robotics, material handling equipment, and precision manufacturing applications requiring accurate linear positioning. Machine builders, maintenance technicians, and automation integrators use this actuator for new machine construction, production line upgrades, retrofits, and replacement of worn linear motion assemblies. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"717\" data-end=\"734\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"736\" data-end=\"1433\"\u003eThe THK KR4620A-0590 belongs to THK's KR46 Series LM Guide Actuator family, integrating a U-shaped high-rigidity outer rail, LM Guide bearings, and a precision ball screw into a compact, enclosed actuator. Its 20 mm ball screw lead enables high-speed travel while maintaining excellent rigidity and positioning accuracy. Designed for direct coupling to a NEMA 23 stepper or servo motor, the actuator provides smooth, low-friction operation and four-way equal load capability, making it ideal for automated assembly systems, pick-and-place equipment, inspection stations, machine tools, and industrial production equipment operating under demanding conditions. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1435\" data-end=\"1464\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1466\" data-end=\"2519\"\u003e• Brand: THK\u003cbr data-start=\"1478\" data-end=\"1481\"\u003e• Part Number: KR4620A-0590\u003cbr data-start=\"1508\" data-end=\"1511\"\u003e• Product Type: LM Guide Ball Screw Actuator \/ Linear Positioner\u003cbr data-start=\"1575\" data-end=\"1578\"\u003e• Series: KR46 LM Guide Actuator\u003cbr data-start=\"1610\" data-end=\"1613\"\u003e• Drive Method: Precision Ball Screw\u003cbr data-start=\"1649\" data-end=\"1652\"\u003e• Ball Screw Lead: 20 mm\u003cbr data-start=\"1676\" data-end=\"1679\"\u003e• Stroke (Travel): 590 mm\u003cbr data-start=\"1704\" data-end=\"1707\"\u003e• Overall Length: Approximately 840 mm\u003cbr data-start=\"1745\" data-end=\"1748\"\u003e• Guide Type: Integrated LM Guide Actuator\u003cbr data-start=\"1790\" data-end=\"1793\"\u003e• Motor Compatibility: NEMA 23 Stepper or Servo Motor\u003cbr data-start=\"1846\" data-end=\"1849\"\u003e• Coupling Bore: 9.5 mm Diameter\u003cbr data-start=\"1881\" data-end=\"1884\"\u003e• Carriage Dimensions: 105 × 53 mm\u003cbr data-start=\"1918\" data-end=\"1921\"\u003e• Carriage Mounting Pattern: 46 × 46 mm\u003cbr data-start=\"1960\" data-end=\"1963\"\u003e• Rated Maximum Speed: Up to 1,000 mm\/s (KR46 Series, 20 mm lead)\u003cbr data-start=\"2028\" data-end=\"2031\"\u003e• Rated Thrust: 359 N\u003cbr data-start=\"2052\" data-end=\"2055\"\u003e• Estimated Motor Capacity: 400 W\u003cbr data-start=\"2088\" data-end=\"2091\"\u003e• Load Direction: Four-Way Equal Load Capability\u003cbr data-start=\"2139\" data-end=\"2142\"\u003e• Construction: High-rigidity U-shaped outer rail with integrated LM Guide and ball screw\u003cbr data-start=\"2231\" data-end=\"2234\"\u003e• Features: Compact design, enclosed ball screw, high-speed operation, low friction, high rigidity, excellent positioning accuracy, direct motor coupling, maintenance-friendly construction, supplied with 3 photo gate sensors on this configuration. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2521\" data-end=\"2545\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2547\" data-end=\"2645\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• THK KR4620A-0490\u003cbr data-start=\"2565\" data-end=\"2568\"\u003e• THK KR4620A-0690\u003cbr data-start=\"2586\" data-end=\"2589\"\u003e• THK KR4610A-0590\u003c\/p\u003e","brand":"THK","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51713990623534,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_7152b6c2-0dac-4ba0-bfdc-270307205b08.jpg?v=1770413151","url":"https:\/\/plgautomation.com\/products\/thk-kr4620a-0590-lm-guide-ball-screw-actuator-590mm-stroke-20mm-lead-nema23","provider":"PLG Automation ","version":"1.0","type":"link"}
