Each jaw is individually numbered 1, 2, and 3 (stamped C097-1, C097-2, C097-3) for matched-set assembly, ensuring proper scroll engagement and concentricity when installed in the correct jaw slots. The jaws feature a fine-pitch serrated base (master jaw interface teeth clearly visible in photos) that engages the chuck's master jaws, and the top surface is ground flat and unfinished, allowing the machinist to bore or machine the gripping face to the required workpiece diameter for precision work-holding. Samchully is a South Korean manufacturer of precision chucks and workholding equipment; the OJ-SC series denotes outside-jaw (OJ) configuration for a scroll chuck (SC) with the 190 designation indicating the 190 mm (approximately 7.5 in) chuck body diameter. These jaws are sold as a complete matched set of three and are intended as replacement or spare top jaws for compatible Samchully 3-jaw scroll chucks of that size.\u003c\/p\u003e\n\u003ch3 style=\"margin-top:24px;margin-bottom:12px;font-size:16px;color:#56555b;border-bottom:2px solid #85c94f;padding-bottom:6px;\"\u003eProduct Specifications\u003c\/h3\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:14px;\"\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eCompatible Chuck Diameter\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e7.5 in (190 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eNumber of Jaws in Set\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eJaw Configuration\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eTop jaws (two-piece style, mounts on master jaws)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eJaw Type\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eHard (unfinished, to be bored by user)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eJaw Orientation\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eOutside jaws (OJ)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eChuck Type Compatibility\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003e3-jaw scroll chuck (SC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eBase Interface\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eFine-pitch serrated (T-nut \/ serrated master jaw engagement)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eJaw Numbering\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eIndividually stamped 1, 2, 3 (C097-1, C097-2, C097-3)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eManufacturer\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eSamchully\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#ffffff;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eManufacturer Part Number\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eOJ-SC-190\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f8f9fa;\"\u003e\n\u003ctd style=\"padding:8px 12px;font-weight:600;color:#56555b;border-bottom:1px solid #eee;width:40%;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"padding:8px 12px;border-bottom:1px solid #eee;\"\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"AnneMarie","offers":[{"title":"Default Title","offer_id":48486540247255,"sku":"6329t101B","price":320.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0736\/0626\/7095\/files\/samchully-oj-sc-190-hard-lathe-chuck-jaws-1.jpg?v=1776196211","url":"https:\/\/dansdiscounttools.com\/products\/samchully-oj-sc-190-hard-top-jaws-7-5in-3-jaw-lathe-chuck-set-of-3","provider":"Dan's Discount Tools","version":"1.0","type":"link"}
