摘要：
A wheel bearing seal (7, 19, 20) has an annular sealing plate (10 or 21) and a slinger (11 or 11′). The sealing plate (10 or 21) has a metal core (12 or 22) and sealing member (13 or 23). The sealing member (13 or 23) has a first side lip (13a or 23a), a second side lip (13b or 23b), and a grease lip (13c or 23c). The slinger (11 or 11′) has a cylindrical portion (11a or 11a′) and an upstanding portion (11b, 11b′). The first and second side lips (13a or 23a and 13b or 23b) slidably contact the upstanding portion. The grease lip (13c or 23c) slidably contacts with the cylindrical portion (11 a or 11a′). A relationship, F1+F2≦1.5×F3, exists between contacting loads F1 and F2, respectively, of the first and second side lips (13a or 23a and 13b or 23b) and a fastening force F3 of the grease lip (13c or 23c).
