There are many kinds, types and sizes of rolling fag bearings. In order to make the mechanical device play the expected performance, it is very important to select the appropriate select fag bearings.
In order to select fag bearings, it is necessary to analyze many important factors, study and evaluate the procedures for selecting fag bearings from various angles. There are no special specifications.
Master the service conditions of mechanical devices and fag bearings, etc
Specify the requirements for fag bearings
Select the type of fag bearing
Select fag bearing configuration mode
Select fag bearing size
Select fag bearing specifications
Select the installation method of fag bearing
The premise of choosing suitable fag bearings is to correctly grasp the use position, use conditions and environmental conditions of fag bearings in mechanical devices. To do this, we need to obtain the following data and information:
Function and structure of mechanical device
Application position select fag bearings
Fag bearing load (size, direction)
Vibration and impact
Fag bearing temperature (ambient temperature, temperature rise)
Ambient atmosphere (corrosive, clean, lubricating)
Disassembly of fag bearing with cylindrical hole of vibrating screen
The inner ring can be easily removed by pressure machinery. At this time, pay attention to let the inner ring bear its pulling force.
The inner ring of fselect fag bearings of large vibrating screen is disassembled by oil pressure method. Oil pressure is applied through the oil hole on the shaft to make it easy to pull. The wide fag bearing is disassembled by the combination of oil pressure method and drawing fixture.
Induction heating method can be used to disassemble the inner ring of fag bearing of Nu and NJ cylindrical roller vibrating screen. It is a method of drawing after heating the part in a short time to expand the inner ring.
Disassembly of tapered select fag bearings
Disassemble the relatively small fag bearing with tight set sleeve, support the inner ring with the stop block fastened on the shaft, turn the nut back several times, and then use the cushion block to knock it down with a hammer.
