How to better maintain TIMKEN imported bearings to avoid heating



Maintaining the bearing is a necessary condition for the operation of the imported bearings of TIMKEN. The common maintenance is to lubricate the bearing. In reading how to select the lubrication method of the bearing, under the premise of understanding the lubrication method of the bearing, it is also very good to understand the maintenance of the bearing system. If necessary, let us look at how to carry out bearing lubrication maintenance.

1. Keep the bearing lubricated clean

Before inspecting the imported bearings of TIMKEN, the surface of the bearing should be cleaned first, and then the oil seal of the bearing and its surrounding parts should be carefully inspected. If there are any bad symptoms, be sure to replace them. The bad oil seal will cause damage and make the bearing cloud. The equipment is not properly stopped and the equipment is shut down.

2. Pay attention to cover exposed bearings

Do not expose the bearings to contaminants or moisture when inspecting TIMKEN bearings. If the work is interrupted, the machine should be covered with a piece of oil-paper plastic or similar material. If the unshielded bearing is cleaned without performing disassembly and may be inspected, use a brush for application to clean with a petroleum solvent, then dry it with a lint-free cloth or blow it with compressed air (be careful not to let The bearing assembly starts to rotate). Check the track faces, retainers and beads of the bearing with a small mirror and a probe similar to that used by dentists. Do not clean the bearing with a sealing cover or dustproof; just wipe the outer surface. If the bearing is damaged, it needs to be replaced. Replacing bearings during regular downtime maintenance is far more economical than the loss of sudden downtime selected due to damage to the array.

3. Check the lubricant of the bearing

Lubricants are important not only for bearings but also for all bearings. However, please note that it is not advisable to add too much grease to TIMKEN bearings. Then it is to replace the lubricant of the bearing. Bearings lubricated with oil should be refilled with fresh oil and allowed to rotate at low speed for a few minutes if the old oil is drained. As much as possible, allow the oil to collect the contaminants from the wreckage and then vent the oil. Bearings lubricated with grease should be replaced with any contact with the cotton material when the grease is replaced. Since these residual fibers may be wedged between the rolling elements and cause damage, in particular the application of the bearing needs to pay attention to this problem.

How to remove oil stains on INA bearings



INA bearings are often used, oil can reduce the service life of bearings, then how do we remove the oil on the INA bearings? The following teaches you how to easily remove the oil stain on the INA bearing.

Bearings hardened by soft dry oil or rust-proof paste should be immersed in hot oil of 100 ° C ~ 200 ° C, clamp the bearing with pliers, and brush the oil on the bearing with a brush. The soft dry oil or anti-rust paste is melted when heated to 100 ° C ~ 200 ° C, and is easily washed out from the gap of the bearing. Sometimes the bearing is shaken several times in the oil. Oil will also flow away from the gap.

When cleaning the radial spherical bearing of the INA bearing, the ball, the bead frame and the inner ring should be laterally turned out from the outer ring and then immersed in the hot oil. When the short cylindrical roller bearing is cleaned, the roller and the bead frame should also be cleaned. The inner ring and the outer ring are disengaged.

When hot oil is cleaned, the temperature of the oil should not exceed 20 °C.
