This bearing type is often used in high-speed applications. Because the inner ring, outer ring, and rollers are in line contact, this bearing type has a large radial load capacity. Various Cylindrical roller bearing configurations are:N,NJ,NF,NU,RNU : integral ribs (flanges)\u003cbr\u003eNH,NP,NUP,NUH : integral and loose ribs\u003cbr\u003eNN,NNU : double-row bearings\u003cbr\u003eConfigurations having integral flanges or loose ribs on both the inner and outer rings can sustain a small amount of axial load. Since this bearing type supports axial loads as sliding action between the end of the rollers and flange faces, axial loading is limited. Double-row Cylindrical roller bearings are used for high-speed, high-accuracy applications such as; main spindle support for lathes, milling machines, and machining centers. Radial clearance of tapered-bore bearings can be adjusted during mounting of the bearing(s) onto the mating journal. Standard cages are pressed steel or polyamide resin. Machined cages of high-strength brass are used for bearings of large dimension or for high-speed applications.\u003c\/p\u003e","brand":"Nachi","offers":[{"title":"Default Title","offer_id":49309940121793,"sku":"Kit10308","price":78.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/0955\/3089\/files\/n304-nachi-cylindrical-bearing-steel-cage-japan-20x52x15-bearings-vxb-ball-bearings-1_5aadf2b4-7e44-4282-b5b9-6530eff24fd1.jpg?v=1748646706","url":"https:\/\/smallbearings.com\/zh\/products\/n304-nachi-cylindrical-bearing-ste","provider":"Small Bearings","version":"1.0","type":"link"}
