> Industry newsLimit of sliding bearing contact angle
2020-05-25
The limit of the contact angle of sliding bearings is 120 °. When the sliding bearing wears to this contact angle, the liquid lubrication will be destroyed. Therefore, the smaller the contact angle, the better, without affecting the compression conditions of the sliding bearing. From the theoretical analysis of the frictional force distance, when the contact angle is 60 °, the friction torque is the smallest. Therefore, it is recommended that for sliding bearings with a speed higher than 500r / min, the contact angle should be 60 ° and the sliding bearings with a speed lower than 500r / min The contact angle can be 90 ° or 60 °.
