    2類:http://www.yr-jx.com/chanpin/zhoucheng/04.gif圓柱滾子軸承 cylindrical roller bearingsNU000、N0000 NJ NN NNU 產品名稱 [/url]圓柱滾子軸承產品型號NU2236NJ1040等等行業應用圓柱滾子軸承主要用于電機、機床、石油、軋機裝卸搬運機械和各類產業機械。產品特點圓柱滾子軸承屬分離型軸承,安裝與拆卸非常方便。圓柱滾子軸承分為單列、雙列和四列。 [/url]   根據軸承裝用滾動體的列數不同,圓柱滾子軸 承可分為單列、雙列和多列圓柱滾子軸承。其中應 用較多的是有保持架的單列圓柱滾子軸承。此外,還有單列或雙列滿裝滾子等其它結構的圓柱滾子軸承。   單列圓柱滾子軸承根據套圈擋邊的不同分為N型、NU型、NJ型、NF型和NUP型等。圓柱滾子軸承承受的徑向負荷能力大,根據套圈擋邊的結構也可承受一定的單向或雙向軸向負荷。 [/url]NN型和NNU型雙列圓柱滾子軸承結構緊湊,剛性強,承載能力大,受載荷后變形小,大多用于機床主軸的支承。FC、FCD、FCDP型四列圓柱滾子軸承可承受較大的徑向載荷,多用于軋機等重型機械上。 圓柱滾子軸承:可在高速運行狀態承受重的徑向負荷,單列EC型設計的圓柱滾子軸承具優化內部曲線,可提高軸承的徑向和軸向負荷能力,同時提高對角度和對準誤差的調節能力及改善潤滑情況,省略了保持架的滿滾子軸承可具有最多數目的滾子。適用于非常重負荷和中等速度的工況。 [/url]各項參數 http://www.yr-jx.com/chanpin/zhoucheng/2006512111446983.jpghttp://www.yr-jx.com/chanpin/zhoucheng/200651211178178.gifN設計內圈有兩個整體式法蘭,外圈不帶法蘭。軸相對于軸承座的軸向位移可在兩個方向上在軸承內承受。因此,這些軸承用作非定位端軸承。NU設計NU設計的軸承外圈有兩個整體式法蘭,內圈不帶法蘭。軸相對于軸承座的軸向位移可在兩個方向上在軸承內承受。因此,這些軸承用作非定位端軸承。由于制造和維護上的原因,以圖紙號表示的NU設計的大型軸承的兩個外圈法蘭不一定是整體式的,而會采用松配合法蘭圈的形式。 [/url]NJ設計外圈有兩個整體式法蘭,內圈有一個整體式法蘭。因此,這些軸承適合軸在一個方向上的軸向定位. [/url]NUP設計外圈有兩個整體式法蘭,內圈有一個整體式法蘭和一個松配合法蘭圈形式的非整體式法蘭。這些軸承可用作定位端軸承,即可提供軸在兩個方向上的軸向定位.
