Since linear motion is obtained using a simple mechanism, the slide bush can be used in a wide variety of applications, including transportation equipment, food processing equipment, and semiconductor manufacturing equipment.\u003cbr\u003e\n\n\u003cbr\u003e\n\nThe outer cylinder of our LM ball bushings contains a resin ball retainer for low acoustic, low-cost requirement that is perfectly designed to control the circulation of ball elements, resulting in smooth linear motion. \u003cbr\u003e\n\n\u003cbr\u003e\n\nDouble lip-seals reduce the grease leakage, keeping the same function as UU seals which prevent the foreign particles from entering the bush.\u003cbr\u003e\n\n\u003cbr\u003e\n\nOur Linear ball bushings are fully compatible with a variety of shaft types.\u003cbr\u003e\n\n\u003cbr\u003e\n\nNumber of ball circuits: 4\u003cbr\u003e\n\nInside dr: 12mm (tolerance 0 to -6µm)\u003cbr\u003e\n\nOutside D: 21mm (tolerance 0 to -13µm)\u003cbr\u003e\n\nLength L: 30mm (tolerance 0 to -0.2µm)\u003cbr\u003e\n\nB: 23mm (tolerance 0 to -0.2µm)\u003cbr\u003e\n\nW: 1.3mm\u003cbr\u003e\n\nD1: 20mm\u003cbr\u003e\n\nEccentricity: 8µm\u003cbr\u003e\n\nRadial clearance maximum: -4µm\u003cbr\u003e\n\nBasic load rating dynamic: 510N\u003cbr\u003e\n\nBasic load rating static: 784N\u003cbr\u003e\n\nMass: 42g\u003cbr\u003e\n\nShaft dia: 12mm","brand":"THK","offers":[{"title":"Default Title","offer_id":58746450051453,"sku":"LM12UU-THK","price":16.86,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0588\/9684\/2842\/files\/59009xxxl.jpg?v=1715758657","url":"https:\/\/bearing-king.co.uk\/products\/lm12uu-thk-sealed-closed-linear-ball-bushing-12x21x30mm","provider":"Bearing King","version":"1.0","type":"link"}
