It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self-smoothing ability. It is especially suitable for heavy loads, low speeds, reciprocating or swinging situations that are difficult to smooth and form an oil film, and are not afraid of water wash and other acid erosion. And scour.
Oil-free bearing means that the bearing can operate normally without or with less oil, instead of not requiring refueling at all.
Advantages
In order to reduce the internal conflict and wear of the bearing and prevent sticking, most of the bearings need to add smooth oil to ensure the smooth and reliable operation of the bearing to extend the fatigue life of the bearing;
eliminates environmental pollution caused by leakage;
It is suitable for heavy load, low speed, reciprocating or swinging and other occasions that are difficult to smooth and form oil film;
Oil-free bearing
It is not afraid of erosion and erosion by water and other acids;
Inlaid bearings not only save oil and energy, but also have a longer operating life than ordinary sliding bearings;
Device precautions
The process of the oil-free bearing installation is also the same as other bearings. Some details need to be paid attention to:
(1). Check whether there are bumps, protrusions, etc. on the cooperating surface of the shaft and the shaft shell.
(2). Whether there is dust or mold sand attached to the surface of the bearing shell.
(3). Although it is a small bump, protrusion, etc., if there is any, use oil grindstone or fine sandpaper to remove it.
(4) In order to prevent bumps during packaging, a small amount of smooth oil should be applied to the outer surface of the shaft and shaft housing.
(5) The hardness of the oil-free bearing may be reduced due to overheating, and it must not exceed 100 degrees.
(6), the retainer of the oil-free bearing and the sealing plate must not be applied.
