    • A sealing device for a bearing includes first and second annular sealing plates (1, 2) accommodated within an annular end space between inner and outer races (11, 12). Each of the first and second sealing plates (1, 2) is of a generally L-shaped section including a cylindrical (16, 26) wall and a radial upright wall (1a, 2a), and an elastic seal lip element (38). The first sealing plate (1) is secured with the radial upright wall (1a) thereof positioned adjacent respective end faces of the inner and outer races (11, 12), and the radial upright wall (1a) of the first sealing plate (1) has a free end remote from the cylindrical wall (1b) of the first sealing plate (1) spaced a predetermined distance from the cylindrical wall (2b) of the second sealing plate (2) to thereby form a radial gap (4). The radial upright wall (1a) of the first sealing plate (1) also has an outer side face (B) set back inwardly from a free end face (A) of the cylindrical wall (2b) of the second sealing plate (2).
    • 用于轴承的密封装置包括容纳在内圈和外圈(11,12)之间的环形端部空间内的第一和第二环形密封板(1,2)。 第一和第二密封板(1,2)中的每一个具有包括圆柱形(16,26)壁和径向直立壁(1a,2a)的大致L形部分,以及弹性密封唇元件(38) 。 第一密封板(1)被固定,其径向直立壁(1a)位于内圈和外圈(11,12)的相应端面附近,并且第一密封板(1)的径向直立壁(1a) )具有远离第一密封板(1)的圆柱形壁(1b)的自由端,其与第二密封板(2)的圆柱形壁(2b)间隔预定距离,从而形成径向间隙(4)。 第一密封板(1)的径向直立壁(1a)还具有从第二密封板(2)的圆筒壁(2b)的自由端面(A)向内设置的外侧面(B) 。
