How to seize the best opportunity to bearing oil change

Whether can for unlimited use of grease, affirmative answer is not possible. Because of the use of too much grease, is to the bearing has a lot of harm.
The advantages of the grease
Grease on bearing have very good effect, its adhesion, abrasion resistance, temperature tolerance, rust and lubricity are good, can improve the high temperature oxidation resistance, delay aging, can dissolve carbon deposition, prevent poly metal abrasive dust and oil pollution, the improved mechanical wear, pressure and corrosion resistance.
The shortcomings of the grease
But if the more grease filling amount, the greater the friction torque.The same filling amount, the sealed bearing friction torque is greater than the open bearing.Grease filling quantity of bearing internal space volume after 60%, friction torque no longer increases obviously.This is due to open in the bearing grease has been most extrusion, but also has lost in the sealed bearing grease.

The best time to bearing oil change
With the increment of grease filling, bearing temperature rise straight line, the same filling amount, sealed bearing temperature rise is higher than the open bearings.
It is generally believed that sealed rolling bearing grease filling amount, shall not be more than 50% or so of the internal space.
Generally speaking, the bearing lubrication plan are set according to time.Equipment suppliers usually lubrication plan according to the operation time.And equipment suppliers in the process of their maintenance plan regularly for the amount of lubricating oil to join the instruction.For staff, the short-term replacement lubricating oil is a very common thing, but often add more grease.
For lubrication bearing, has a fixed concept of prevention, that is in the bearing is not stopped by a dry and collapse operation keep equipment under the condition of reasonable operation.
But, we have to do to keep balance between lubrication excessive hunger and a lot of lubrication.If an oil change is too little, the bearing will be scrapped in advance;If there is excessive oil change, bearing would get into trouble or long-term harm power coil and roll line.
