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: 5\u003cbr\u003e\n\nInside dr: 20mm (tolerance 0 to -7µm)\u003cbr\u003e\n\nOutside D: 32mm (tolerance 0 to -16µm)\u003cbr\u003e\n\nLength L: 42mm (tolerance 0 to -0.2µm)\u003cbr\u003e\n\nB: 30.5mm (tolerance 0 to -0.2µm)\u003cbr\u003e\n\nW: 1.6mm\u003cbr\u003e\n\nD1: 30.5mm\u003cbr\u003e\n\nEccentricity: 10µm\u003cbr\u003e\n\nRadial clearance maximum: -6µm\u003cbr\u003e\n\nBasic load rating dynamic: 882N\u003cbr\u003e\n\nBasic load rating static: 1370N\u003cbr\u003e\n\nMass: 100g\u003cbr\u003e\n\nShaft dia: 20mm","brand":"THK","offers":[{"title":"Default Title","offer_id":58746449723773,"sku":"LM20UU-THK","price":22.55,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0588\/9684\/2842\/files\/58998xxxl.jpg?v=1715758658","url":"https:\/\/bearing-king.co.uk\/products\/lm20uu-thk-sealed-closed-linear-ball-bushing-20x32x42mm","provider":"Bearing King","version":"1.0","type":"link"}
