The Teflon liner is bonded to the inner diameter surface of the race, allowing for sliding motion between the spherical ball and the Teflon liner surface.
The Teflon liner has self-lubricating properties, eliminating the need for lubricants such as grease.
Therefore, it is effective for use in locations where oil is undesirable or where lubrication is difficult or impossible.
Additionally, since it does not require lubrication mechanisms, it can also effectively reduce maintenance costs.
The Teflon type spherical is suitable for use under low-speed oscillation.
It also exhibits relatively good performance under vibration loads. Therefore, when issues such as excessive friction, seizing, or fatigue damage occur with metal types, or when fretting at the sliding surfaces becomes problematic, replacing with the Teflon type is an effective measure.
