In the case of grease lubrication, if the recommended amount of grease is added to TIMKEN bearings (or added lubrication) during the first few hours or several days (depending on the speed of the application may be), TIMKEN bearingsthe resulting friction is much higher than the originally calculated value. This is because the grease needs time to stir, re-distribution in the bearing of free space. To estimate the impact of such factors, will start rolling friction torque is multiplied by a coefficient, light series bearings, heavy series bearings 4. After the "run" phase, the friction torque dropped to about equivalent to the level of oil lubrication, and in many cases, may even drop to a lower level. If adding an excess of grease in the bearings, may lead to increased friction in the bearings.
TIMKEN bearing injury, not all parts can be repaired, only those with the value of maintenance TIMKEN bearing damage only in need of repair should be damaged TIMKEN bearing demolition inspection and appraisal. Is close to or reach the expected service life, there is no necessary repairs.
Addition to the judge with the repair conditions, such as: TIMKEN bearing structural performance and manufacturing requirements to understand and repair a variety of tools, equipment, measurement and repair techniques to master degree. In addition, repair costs and repair TIMKEN bearing performance can meet the work requirements of the host must be analyzed. TIMKEN bearing spare parts inadequate preparation or procurement is just difficult and failure is difficult to timely replacement of TIMKEN bearings, you need to consider the repair costs and procurement constraints.
