Some tips about the use of FAG bearings

wallpapers Resource 2020-11-12
Since 2001, FAG bearings have played an active and important role in the group's aerospace, automotive and industrial fields, covering all applications in the production machinery, power transmission and railway, heavy industry and consumer goods industries. FAG bearings produce various ball bearings and roller bearings with an outer diameter from 3 mm to 4.25 meters, including standard products based on samples and non-standard products based on special requirements of users.


FAG bearing installation

When the inner ring of FAG imported bearings is tightly fitted with the shaft, and the outer ring is loosely fitted with the bearing housing hole, the bearing can be press-fitted on the shaft with a press, and then the shaft and the bearing can be installed in the bearing housing hole. When the end face of the bearing inner ring is filled with an assembly sleeve made of soft metal material (copper or mild steel), the inner diameter of the assembly sleeve should be slightly larger than the journal diameter, and the outer diameter should be slightly smaller than the rib of the bearing inner ring, So as not to press on the cage. If the bearing ring is tightly fitted with the shaft and the seat hole, the inner ring and outer ring must be installed into the shaft and the seat hole at the same time. The structure of the assembly sleeve should be able to tighten the end faces of the inner ring and the outer ring at the same time.

 

Maintenance of FAG bearings

Generally, the new bearing is refueled by removing the cover, and it can be used without refueling, but it will not last long. FAG Imported bearings add oil and molybdenum disulfide lithium base grease, because of its high-temperature resistance and wear resistance. The calcium-based grease in the past is gradually phased out due to its inability to withstand high temperatures, and the original bearing oil should be removed when it is added. Motor bearings should not exceed 70 degrees, especially high-speed bearings, the high-speed loss is extremely high, you should always add oil, do not exceed 60 degrees for the gearbox, because the gearbox is lubricated with organic oil, the summer temperature is 60 degrees. The bearing on the pump should not exceed 65 degrees. In order to ensure the normal operation of FAG imported bearings, good smoothness is necessary. The rated load and limit speed of the rolling bearing is determined under the assumption of smoothness and appropriateness. The so-called smoothness and appropriateness mean that the selection of a smoothing agent is appropriate, the amount of smoothing is appropriate and smooth. Defects are often one of the main reasons for the early destruction of bearings.
