圓柱滾子軸承

1、圓柱滾子軸承產(chǎn)品名稱圓柱滾子軸承產(chǎn)品型號(hào)NU2236NJ1040等等行業(yè)應(yīng)用圓柱滾子軸承主要用于電機(jī)、機(jī)床、石油、軋機(jī)裝卸搬運(yùn)機(jī)械和各類產(chǎn)業(yè)機(jī)械。產(chǎn)品特點(diǎn)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。 根據(jù)軸承裝用滾動(dòng)體的列數(shù)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(yīng) 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(jié)構(gòu)的圓柱滾子軸承。 單列圓柱滾子軸承根據(jù)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(fù)荷能力大，根據(jù)套圈擋邊的結(jié)構(gòu)也可承受一定的單向或雙向軸向負(fù)荷。 NN型和NNU

2、型雙列圓柱滾子軸承結(jié)構(gòu)緊湊，剛性強(qiáng)，承載能力大，受載荷后變形小，大多用于機(jī)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(jī)等重型機(jī)械上。 圓柱滾子軸承：可在高速運(yùn)行狀態(tài)承受重的徑向負(fù)荷，單列EC型設(shè)計(jì)的圓柱滾子軸承具優(yōu)化內(nèi)部曲線，可提高軸承的徑向和軸向負(fù)荷能力，同時(shí)提高對(duì)角度和對(duì)準(zhǔn)誤差的調(diào)節(jié)能力及改善潤(rùn)滑情況，省略了保持架的滿滾子軸承可具有最多數(shù)目的滾子。適用于非常重負(fù)荷和中等速度的工況。 各項(xiàng)參數(shù) N設(shè)計(jì)內(nèi)圈有兩個(gè)整體式法蘭，外圈不帶法蘭。軸相對(duì)于軸承座的軸向位移可在兩個(gè)方向上在軸承內(nèi)承受。因此，這些軸承用作非定位端軸承。NU設(shè)計(jì)NU設(shè)計(jì)的軸承外圈有兩個(gè)

3、整體式法蘭，內(nèi)圈不帶法蘭。軸相對(duì)于軸承座的軸向位移可在兩個(gè)方向上在軸承內(nèi)承受。因此，這些軸承用作非定位端軸承。由于制造和維護(hù)上的原因，以圖紙?zhí)柋硎镜腘U設(shè)計(jì)的大型軸承的兩個(gè)外圈法蘭不一定是整體式的，而會(huì)采用松配合法蘭圈的形式。NJ設(shè)計(jì)外圈有兩個(gè)整體式法蘭，內(nèi)圈有一個(gè)整體式法蘭。因此，這些軸承適合軸在一個(gè)方向上的軸向定位.NUP設(shè)計(jì)外圈有兩個(gè)整體式法蘭，內(nèi)圈有一個(gè)整體式法蘭和一個(gè)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(gè)方向上的軸向定位.軸承型號(hào) Designation外型尺寸Principal Dimension額定負(fù)荷(kN)Basic Load Rating
