The Teflon liner is bonded to the inner surface of the race, allowing for sliding motion between the spherical ball and the Teflon liner surface.
Because the Teflon liner has self-lubricating properties, lubricants such as grease are unnecessary.
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 is effective in reducing maintenance costs.
The Teflon type spherical is suitable for use under low-speed oscillation.
It also exhibits relatively good performance under vibrational loads. Therefore, if the metal type experiences excessive friction, seizing, or fatigue failures, or if fretting of the sliding surfaces becomes a problem, replacing it with the Teflon type is an effective measure.
