圓柱滾子軸承 CYLINDRICAL ROLLER BEARING

　圓柱滾子軸承是一種可分離型軸承。其內、外圈與滾子是線性接觸，摩擦係數小，承受徑向載荷能力較大。適合於電機、汽車、傳動軸、齒輪軸等。雙列圓柱滾子軸承適用於機床主軸。

　 This type of bearings is separable. As their rollers linearly come into contact with inner ring and outer ring with less coefficient of friction, these bearings have very good capacity of radial load, suitable for electric motors, automobiles, transmission shafts, gear shafts and so on. Double row cylindrical roller bearings are good at the spindles of machine tools.
