HSR30LR1SS(GK) Linear Guide Block","description":"\u003cdiv\u003e\u003cp\u003eThe THK HSR30LR1SS(GK) Linear Guide Block delivers high-load, high-precision, recirculating-ball motion on THK HSR30-series rails, featuring a long-carriage design, a four-row ball contact design, and four-way equal-load capability for enhanced rigidity. This LR (Long Standard) block for 30 mm rails measures 120.6 mm in length, 60 mm in width, and 45 mm in overall height, with a carriage height of 38 mm, mounting hole spacing of 40 × 60 mm, and M8 × 10 mm mounting threads. It uses precision-ground raceways and hardened bearing steel construction, with SS end and side seals and a GK lubrication system, delivering high rigidity and low-friction operation, and an interchangeable design with a long service life. Rail compatibility includes 30 mm THK rails with a rail width of 28 mm, rail height of 26 mm, and rail mounting hole pitch of 80 mm. Dynamic load rating is 48.9 kN and static load rating is 70.2 kN; block weight is approximately 1.1 kg. Common applications include CNC machining centers, milling machines, gantry systems, semiconductor equipment, automated production lines, packaging machinery, precision measuring equipment, medical devices, and robotics. It is commonly used by maintenance teams, OEM machine builders, and system integrators for repair, retrofit, expansion, and replacement. Common replacements include THK HSR30LR1UU(GK) and THK HSR30LR1SSC1(GK).\u003c\/p\u003e\u003c\/div\u003e","brand":"THK","offers":[{"title":"New","offer_id":46242804891882,"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-co-ltd-hsr30lr1ssgk-linear-guide-block","provider":"GTG Hardware","version":"1.0","type":"link"}
