The Teflon liner is adhered to the inner diameter surface of the race and allows for sliding motion between the ball’s spherical surface and the Teflon liner surface.
Since the Teflon liner has self-lubricating properties, lubricants such as grease are unnecessary.
Therefore, it is effective for use in areas where oil is undesirable or lubrication is difficult or impossible.
Moreover, 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.
Additionally, it exhibits relatively good performance under vibrational loads. Therefore, when issues such as excessive friction, seizing, fatigue failure, or fretting of sliding surfaces occur with metal types, replacing them with Teflon types can be an effective countermeasure.
