> Industry newsLimit of contact angle of sliding bearing
2020-07-27
The limit of contact angle of sliding bearing is 120 °. When the sliding bearing is worn to this contact angle, the liquid lubrication will be destroyed. Therefore, the smaller the contact angle, the better. According to the theoretical analysis of friction distance, when the contact angle is 60 °, the friction torque is the minimum. Therefore, it is suggested that the contact angle of sliding bearing with rotating speed higher than 500r / min should be 60 ° and that of sliding bearing with rotating speed lower than 500r / min can be 90 ° or 60 ° respectively.
