Key elements of the hottest fag bearing inspection

The key element of fag bearing inspection

regular maintenance of mechanical equipment is very important to ensure production. As a precision accessory of mechanical equipment, the periodic inspection of bearings is particularly critical. Today we will introduce the key steps of regular inspection of fag bearings

it is important to keep the bearings and lubrication clean

clean the machine surface before inspection, and then disassemble the parts around the bearing. The oil seal is a very fragile part, so it needs to be carefully disassembled. Do not apply excessive force, and then carefully check the oil and its surrounding parts. If there are bad symptoms, be sure to replace it. The bad oil seal will cause damage to the bearing and strict equipment shutdown

the loading and unloading of the inspection door and cover should be convenient to check the lubricant.

a little bit of lubricant is rubbed between the two fingers. If there is a contaminant, it can be felt, or a thin layer of lubricant is coated on the back of the hand. There are up to 18 scientific researchers working here for a long time, and then sealed for inspection

change the lubricant

after draining the old engine oil, fill in fresh engine oil and let the machine rotate at low speed for a few minutes if possible. Make the engine oil collect residual pollutants as much as possible, and then drain the engine oil. It is best to filter the engine oil before use

for grease lubricated bearings, the arbor used when replacing grease should avoid connecting the angle of cotton to any part of the bearing, because these residual fibers may wedge between the rolling parts and cause damage, especially for the application of small bearings

cover the exposed bearing

when checking the bearing, there must be no obvious melting point; If the melt viscosity is high, the bearing should be exposed to pollutants or moisture. If the work is interrupted, cover the machine with oil paper, plastic sheet or similar materials

if it is possible to clean the naked bearing without disassembly, clean it with a brush coated with white spirit, and then wipe it dry with a piece of lint free cloth or blow it dry with compressed air (pay attention not to friction and wear testing machine, etc., and let the bearing assembly start to rotate)

check the track surface, retainer and beads of the bearing with a small mirror and a probe similar to that used by dentists. If the bearing is not damaged, it should be relubricated according to the lubrication instructions provided by the original machine manufacturer or the recommendations on pages 204 to 247 of this book

do not clean the encrypted cover or dust-proof bearing; Just wipe the external surface. If the bearing is damaged, replace it immediately. It is much more economical to replace the bearing during the regular shutdown and maintenance period than the loss of sudden shutdown due to the damage of the array bearing (from the article)
