60% of premature bearing failure is caused by: incorrect mounting, lack of lubrication, contamination and/or overdue maintenance
Use the right tools!
To achieve a maximum bearing lifecycle it is necessary:
- to use correct mounting tools and methods
- that machines are aligned properly
- that correct lubrication is performed
It is common knowledge that a correct mounting method extends the bearing life. Controlled stress-free heating with induction heaters prevents unnecessary damage, while retaining the original bearing lubrication. Ideal for sealed bearings (2RS-ZZ). Bearing manufacturers recommend controlled induction heating as the best practice for bearing mounting. During operation the performance of the bearing can be monitored with condition monitoring instruments for temperature, vibration and noise. These regular inspections contribute to establish a trend so that bearing maintenance can be planned. Planned bearing maintenance prevents machine downtime during production runs. Correct dismounting tools and methods help to prevent damage to a bearing or other machine parts.
Plan maintenance!
There are many aspects that play a role in a good maintenance plan. Correctly planned and performed maintenance helps a production department to achieve the best production capacity. It pays to invest in the reliability of critical machines. This prevents unexpected failures or unscheduled shutdowns.
Ordering the right equipment or tools from the right supplier is crucial. Investing in staff training is also important to achieve the best production results. We often notice that buyers, instead of investing money in the requested quality product, try to save money by purchasing cheaper, alternative tools. The mechanics end up needing more time to do their work.
Lubricate!
Ball bearings can wear out faster or become damaged. Common causes are:
- lack of lubrication: oil or grease
- too high temperature
- impurities
- too high a load
- incorrect assembly
When a bearing is damaged it is visually perceptible. A consequence of damage is vibration. Using vibration analysis this can be measured and one can analyse which error has occurred. Immediate action is then required because the consequential damage is considerably greater than the costs of replacing a bearing.
