Generally speaking, non-standard bearings will heat up after starting operation, and after a period of time, they will be in normal condition at a lower temperature (usually 10 ~ 40 degrees higher than the room temperature).The time to normal varies according to the size, form, rotation speed and lubrication method of SKF Bearing, and the heat release conditions around the non-standard bearing. At this time, it takes about 20 minutes Skf Non-Standard Bearing to several hours.
