> Industry newsLimit of contact angle of sliding bearing
2020-07-27
The limit of the contact angle of the sliding bearing 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 pressure conditions of the sliding bearing. From the theoretical analysis of the friction moment, when the contact angle is 60°, the friction moment is the smallest. Therefore, it is recommended that for sliding bearings with a speed higher than 500r/min, a contact angle of 60° and a sliding bearing with a speed lower than 500r/min should be used. The contact angle can be 90° or 60°.
