TIMKEN Bearing Operation Inspection

Source:  skf bearing  Time:  2020-08-27

   It is important to keep TIMKEN bearings and lubrication clean.

   Clean the surface of the machine before inspection, and then disassemble the parts around the TIMKEN bearing. The oil seal is a very fragile part, so it needs to be disassembled carefully without excessive force, and then carefully check the oil seal and its surrounding parts. If it shows bad symptoms, be sure to replace it. A bad oil seal will lead to imported TIMKEN Bearing damage and severe equipment shutdown.


Cover exposed TIMKEN bearings:

   When inspecting TIMKEN bearings, do not expose TIMKEN bearings to pollutants or moisture. If work is interrupted, the machine should be covered with greased paper plastic sheet or similar material. If the unmasked TIMKEN bearing is cleaned without disassembly and inspection is possible, it should be cleaned with a white spirit with a coating brush, and then wiped dry with a lint-free cloth or blown with compressed air Dry (be careful not to let the TIMKEN bearing assembly start to rotate).


Check lubricant:

   Dip a little bit of lubricant and rub between the fingers. If there is contamination, you can feel it, or apply a thin layer of lubricant on the back of the hand, and then seal it for inspection.
 

Replace lubricant:

  Oil-lubricated TIMKEN bearings, after purging the old oil, if possible, pour in fresh oil and let the machine rotate for a few minutes at a low speed. Try to collect the remaining contaminants in the oil as much as possible, and then purify the oil. The oil should be filtered before use. Grease-lubricated TIMKEN bearings should avoid any part of the TIMKEN bearing with cotton material when changing the grease, because these residual fibers may be wedged between the rolling elements and cause damage , Especially the application of small TIMKEN bearings need to pay more attention to this problem.

      It has become more and more important to check the condition of the machine in operation and prepare a thorough inspection plan. Among them, TIMKEN bearing is the focus of attention, because it is the most important rotating part in all machines. Condition monitoring is an important part of preventive maintenance. Early detection of TIMKEN bearing damage to avoid equipment downtime during unplanned maintenance due to TIMKEN bearing damage. Let me introduce you to this method of listening.

 

      It is a very common method to use hearing to identify irregular operation. For example, using an electronic stethoscope to detect abnormal noise of a certain part is used by experienced operators. If the TIMKEN bearing is in good operating condition, it will emit a low whining sound. If it emits a sharp hiss, squeak and other irregular sounds, it usually indicates that the imported TIMKEN bearing is in a bad operating condition.

 

      The sharp squeaking noise may be caused by improper lubrication. Inappropriate TIMKEN bearing clearance can also cause metallic noise. The dents on the track of the TIMKEN bearing outer ring will cause vibration and cause a smooth and crisp sound. If it is caused by knocking scars during installation, it will also produce noise. This noise will vary with the speed of the TIMKEN bearing. If there is intermittent noise, it means that the rolling parts may be damaged. This sound occurs when the damaged surface is rolled over. If there are pollutants in the TIMKEN bearing, it will often cause a hissing sound. Regular and loud noise.

 

      Although TIMKEN bearing damage can be detected by hearing, it is usually already here that the TIMKEN bearing must be replaced immediately. Therefore, a better method, such as the use of electronic condition monitoring equipment, pre-diagnoses the operation of TIMKEN bearings. We provide TIMKEN Bearing 66584/66520, if need it, contact us freely.

 

      Compared with the old method (using a wooden stick or screwdriver against the TIMKEN bearing box and the other end against the ear), the use of advanced instruments can more accurately predict the condition of TIMKEN bearings.

 

      The bearings sold by Eric Bearings Limited are of excellent quality, and the price is much cheaper than other distributors. The products are exported to more than 50 countries and regions in the world, winning wide acclaim from customers and establishing long-term cooperative relations with them. In order to expand the scope of business, we also hope to establish trade relations with more customers and develop together.
