It is commonly installed in bench-mounted hardness testers used in metallurgical laboratories, machine shops, heat treatment facilities, and industrial quality control stations where precise hardness verification of metals is required. Maintenance technicians, calibration specialists, and quality assurance engineers use this component for equipment repair, rebuilds, calibration service, and replacement of worn or damaged mechanical loading arms and wedge assemblies in hardness testing instruments.\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"712\" data-end=\"729\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"730\" data-end=\"1110\"\u003eThe QO185 hardness tester arm and wedge is commonly used in metallurgical laboratories, manufacturing quality control departments, heat treatment facilities, and machine shops where Rockwell hardness testing is performed on steel, aluminum, cast iron, and alloy materials to verify material properties, heat treatment effectiveness, and compliance with engineering specifications.\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1112\" data-end=\"1141\" class=\"PDq2pG_selectionAnchorContainer\"\u003eTechnical Specifications:\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cp data-start=\"1142\" data-end=\"1881\"\u003e• Manufacturer: Unbranded \/ OEM hardness tester component\u003cbr data-start=\"1199\" data-end=\"1202\"\u003e• Model \/ Part number: QO185\u003cbr data-start=\"1230\" data-end=\"1233\"\u003e• Product type: Hardness tester arm and wedge assembly\u003cbr data-start=\"1287\" data-end=\"1290\"\u003e• Equipment type: Rockwell-style hardness testing machine component\u003cbr data-start=\"1357\" data-end=\"1360\"\u003e• Function: Load application and mechanical force transfer for indentation testing\u003cbr data-start=\"1442\" data-end=\"1445\"\u003e• Material: Hardened tool steel (typical industrial construction)\u003cbr data-start=\"1510\" data-end=\"1513\"\u003e• Compatibility: Bench-type hardness testing machines (model-specific fit)\u003cbr data-start=\"1587\" data-end=\"1590\"\u003e• Operation: Manual or mechanical load transfer system\u003cbr data-start=\"1644\" data-end=\"1647\"\u003e• Application: Material hardness measurement (Rockwell scale systems)\u003cbr data-start=\"1716\" data-end=\"1719\"\u003e• Use environment: Industrial QC laboratories and metallurgical testing stations\u003cbr data-start=\"1799\" data-end=\"1802\"\u003e• Function role: Structural force alignment and test load actuation component\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"1883\" data-end=\"1907\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"1908\" data-end=\"2113\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• Mitutoyo Rockwell hardness tester arm assembly (model-specific equivalent)\u003cbr data-start=\"1984\" data-end=\"1987\"\u003e• Wilson \/ Buehler hardness tester load arm and wedge kit\u003cbr data-start=\"2044\" data-end=\"2047\"\u003e• Phase II Rockwell hardness tester mechanical arm replacement kit\u003c\/p\u003e","brand":"PLG Automation ","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51714383544622,"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_5585ba38-8a5f-49ce-8146-d63bd37a0787.jpg?v=1770424862","url":"https:\/\/plgautomation.com\/products\/qo185-hardness-tester-arm-and-wedge","provider":"PLG Automation ","version":"1.0","type":"link"}
