{"product_id":"thk-hsr20a1ssgk-linear-motion-bearing-block","title":"THK HSR20A1SS(GK) Linear Motion Bearing Block","description":"\u003cdiv\u003e\u003cp\u003eThe THK HSR20A1SS(GK) Linear Motion Bearing Block is a precision recirculating ball LM Guide carriage designed for THK HSR20 guide rails, delivering smooth, high-accuracy travel with low friction. Built on THK’s GK interchangeable platform, it combines a Four-Way Equal Load design with stainless steel raceway components (SS) to provide balanced load handling, corrosion resistance, and long service life. This flange-type A block for 20 mm rails measures 30 mm in height, 63 mm in width, and 74 mm in length, with mounting dimensions of 53 × 40 mm and M6 mounting threads; end seals plus side seals protect the raceways. The rail block offers a dynamic load rating of 19.8 kN and a static rating of 27.4 kN and is compatible with grease or oil lubrication, making it suitable for demanding automation tasks. The GK design simplifies maintenance and replacement while maintaining precise motion, and the block is interchangeable with compatible HSR20(GK) rails. Common applications include CNC machining centers, pick-and-place robots, semiconductor equipment, medical devices, automated inspection systems, packaging machinery, and broader precision motion control applications in industrial automation. Typical users—the maintenance teams, OEM machine builders, and system integrators—utilize it for equipment repair, retrofit, expansion, or replacement. Common replacements include HSR20HA1SS(GK), HSR20CA1SS(GK), and SHS20C1SS to sustain compatible performance on THK HSR20 rails.\u003c\/p\u003e\u003c\/div\u003e","brand":"THK","offers":[{"title":"New","offer_id":46242804236522,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-008.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/thk-hsr20a1ssgk-linear-motion-bearing-block","provider":"GTG Hardware","version":"1.0","type":"link"}
