It is constructed of metal for durability in the marine environment and is lubricated with grease to keep the bearing running smoothly under load. The bearing carries the Sierra brand assurance that its replacement parts meet or exceed the performance of the original equipment part they replace, and it ships as a single unit ready for installation in place of a worn or failed gimbal bearing.\u003c\/p\u003e\u003cp\u003eThis bearing is compact, measuring 0.39 x 0.39 x 0.39 inches, and is designed to fit Blackhawk applications from 1994-1995 with serial number F186717 and up. Boat owners servicing their stern drive coupling in this fitment range can use the 18-21001 as a direct fit for that application. As with any drivetrain bearing, replacing a worn gimbal bearing helps prevent excess play, vibration, and premature wear on the connected driveshaft components.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-21001\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Gimbal Bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBearing Type:\u003c\/strong\u003e Ball Bearing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions (L x W x H):\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Thickness:\u003c\/strong\u003e 25 Millimeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Lubricant:\u003c\/strong\u003e Grease\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282294168\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00808282294168\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Limited Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eBlackhawk, 1994-1995, serial number F186717 and up\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-21001 gimbal bearing used for?\u003c\/strong\u003e The 18-21001 is a ball-type gimbal bearing that supports the coupling between the engine and stern drive unit, and it is used to replace a worn or failed gimbal bearing in that application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat boats does the 18-21001 gimbal bearing fit?\u003c\/strong\u003e This bearing fits Blackhawk applications from 1994-1995 with serial number F186717 and up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-21001 an OEM or aftermarket bearing?\u003c\/strong\u003e The 18-21001 is a Sierra-brand replacement bearing designed to meet or exceed the performance of the original equipment gimbal bearing it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-21001 gimbal bearing made from?\u003c\/strong\u003e It is made of metal, which is standard for gimbal bearings that must hold up to marine driveline loads and moisture exposure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-21001 gimbal bearing weigh?\u003c\/strong\u003e The Sierra 18-21001 gimbal bearing weighs 1.2 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-21001 gimbal bearing?\u003c\/strong\u003e It measures 0.39 x 0.39 x 0.39 inches, with an item thickness of 25 millimeters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-21001 gimbal bearing need to be lubricated?\u003c\/strong\u003e Yes, the 18-21001 is compatible with grease lubrication to keep the bearing operating smoothly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of bearing is the Sierra 18-21001?\u003c\/strong\u003e The 18-21001 is a ball bearing, identified by Sierra under bearing number 18-21001.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-21001 come with a warranty?\u003c\/strong\u003e Yes, the 18-21001 gimbal bearing is covered by a limited warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if the 18-21001 is the correct gimbal bearing for my boat?\u003c\/strong\u003e Confirm your application is a Blackhawk from 1994-1995 with serial number F186717 or higher before ordering the 18-21001, since gimbal bearings vary by drive unit and serial number range.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988091711707,"sku":"SIE-18-21001","price":75.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/sie-18-21001_lg__98260.1558139580.500.750.jpg?v=1785189093","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-21001-gimbal-bearing-replaces-mercury-30-879194a02-fits-mercruiser-alpha-bravo-i-ii-iii-gen-ii-sterndrives-non-greasable","provider":"Good Vibes Marina","version":"1.0","type":"link"}
