Is it better to have more bearing grease?

Perhaps everyone knows that the role of lubricating grease is very important in using bearings, so some people may ask, can lubricating grease be used infinitely to lubricate bearings? When should I switch? How much should we exchange?
The answer to whether unlimited amounts of lubricating grease can be added is definitely no. Excessive lubricating grease is harmful to bearings and not beneficial.
Lubricating grease has a good lubricating effect on bearings. His adhesion, wear resistance, temperature resistance, rust resistance, and lubricity are all good, which can improve high-temperature oxidation performance, delay aging, dissolve carbon deposits, prevent the aggregation of metal debris and oil stains, and improve the wear resistance, pressure resistance, and corrosion resistance of machinery. But the more grease is filled, the greater the friction torque. The friction torque of sealed bearings is greater than that of open bearings with the same filling amount. After the amount of lubricating grease filling is equivalent to 60% of the internal space of the bearing, the friction torque no longer increases significantly. This is because most of the grease in the open bearings has been squeezed out, and the grease in the sealed bearings has also leaked.
Generally speaking, the lubrication plan for bearings is determined based on time. Equipment suppliers typically develop lubrication plans based on operating time, and often provide guidance on the amount of grease added during their maintenance planning process.
