| application features: |
|
| BG-250G bearing steel sleeve is a reinforced product with extremely high compression resistance. When lubricating particles are discharged when inlaid graphite is working, a layer of diaphragm is generated between the shaft and the sleeve, which plays a role in lubricating and resisting seizure than single oil. Advantages. It is especially suitable for the supporting parts of hoisting machinery. Example: soil rolling machine support, crane support, etc., but should not be used in water or acid-base occasions. | |
