The Teflon liner is bonded to the inner race surface, allowing for sliding motion between the spherical ball and the Teflon liner surface.
The Teflon liner possesses self-lubricating properties, eliminating the need for lubricants such as grease.
Therefore, it is effective for use in areas where oil is undesirable or lubrication is difficult or impossible.
Additionally, since it does not require a lubrication mechanism, it is effective in reducing maintenance costs.
The Teflon type spherical is suitable for use under low-speed oscillation conditions.
It also exhibits relatively good performance under vibration loads. Thus, when the metal type experiences excessive friction or is prone to seizure and fatigue failure, or when fretting at the sliding surface becomes problematic, replacing it with the Teflon type is an effective solution.
