The Teflon liner is bonded to the inner race surface, allowing for sliding motion between the ball spherical surface 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 locations where oil is undesirable or lubrication is difficult or impossible.
Additionally, since it does not require a lubrication mechanism, it effectively reduces maintenance costs.
The Teflon type spherical is suitable for use under low-speed oscillation.
It also exhibits relatively good performance under vibrational loads. Therefore, when the metal type experiences excessive friction, seizing, or fatigue failure, or when fretting of sliding surfaces becomes an issue, replacing it with the Teflon type is an effective measure.
