Harken engineers have simplified the mechanics by combining the axial and thrust bearings into a single bearing set of V-shaped titanium rollers. The result is a strong, lightweight block that offers unmatched efficiency at high loads, while spinning freely at low loads for smooth easing in light air. Harken V blocks are standard with 3D-molded carbon sideplates, titanium sheave, and captive titanium roller bearings. V blocks are easy to disassemble for inspection and maintenance.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable style=\"border-collapse:collapse;width:100%;max-width:100%;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"text-align:left;border-bottom:1px solid #ddd;padding:8px;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"text-align:left;border-bottom:1px solid #ddd;padding:8px;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eBreaking load (kg)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e13000 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eBreaking load (lb)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e28600 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eLength (in)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e4 3\/16 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eLength (mm)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e107 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eMaximum line Ø (in)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e5\/8 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eMaximum line Ø (mm)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e16 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eMaximum working load (kg)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e6500 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eMaximum working load (lb)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e14300 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eSheave Ø (in)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e3 1\/4 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eSheave Ø (mm)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e82 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eWeight (g)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e364 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003eWeight (oz)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #eee;padding:8px;vertical-align:top;\"\u003e12.84 oz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c!-- sr-faq v=1 vendor=harken source_sha256=410d88123bc21d52566e303c9947adbe3a647f291194a4af4bb4b3578fabccb1 --\u003e\u003ch3\u003eFAQs\u003c\/h3\u003e\u003cdetails\u003e\u003csummary\u003eWhat mounting structure rating is required for safe installation?\u003c\/summary\u003e\u003cdiv\u003e\u003cp\u003eMount the block to structures and anchors that meet or exceed the Maximum Working Load to ensure safety and function.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhat personnel should install and maintain the V Block?\u003c\/summary\u003e\u003cdiv\u003e\u003cp\u003eInstallation, disassembling, and reassembling must be performed by experts;
