A Teflon liner is bonded to the inner race surface, allowing sliding motion between the ball spherical surface 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 places where oil is undesirable or lubrication is difficult or impossible.
Additionally, since it does not require a lubrication mechanism, it is also 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, when the metal type experiences excessive friction or is prone to seizure or fatigue failure, replacing it with the Teflon type can be an effective solution to the fretting issues on the sliding surfaces.
