NMB (Minebea) Spherical Teflon type Lace thick

A Teflon liner is adhered to the inner diameter surface of the race, and it slides on the spherical surface of the ball and the Teflon liner surface.
Since the Teflon liner is self-lubricating, no lubricant such as grease is required.
Therefore, it is effective for use in places where oil is disliked or where lubrication is difficult or impossible.
It is also effective in reducing maintenance costs because it does not require a lubrication mechanism.
The Teflon type spherical is suitable for use under low speed rocking.
It also exhibits relatively good performance even under vibration load. Therefore, if the metal type has too much friction, is prone to seizure or fatigue damage, or if fretting of the sliding surface becomes a problem, it is an effective measure to replace it with the Teflon type.
