The bearing and the bearing seat bear the temperature range
In a certain temperature range, the bearing temperature depends on the added grease [oil]
Key see material.General material 100 degrees below, special material 180 can.In fact, the most critical is your application conditions, because the bearings are precise matching, if the temperature rise, deformation, and high speed, heavy load, it will soon wear, and affect the accuracy of equipment.The most important point, most grease after heating viscosity changes, and soon lead to poor lubrication of bearings, and therefore you choose grease is also a great relationship, you can choose high temperature grease.
In general, the ordinary bearing tempering temperature is around 160 degrees, so the use of the maximum temperature is 120 degrees, the instantaneous temperature should not exceed 140 degrees. If you have special requirements for the working temperature of the tempering temperature, need to adjust the bearing! In addition, bearing temperature is higher than 150 degrees, the high temperature grease retainer or PA46 the metal holder, a rubber sealing ring material requires the use of H-NBR or FKM, NBR. can not be used if the working temperature need to improve, materials and lubricating bearings need to be improved!
Ordinary bearings -40 degrees --+70 degrees between the bearing block and it is the same. It is better to look at some bearing models, but the temperature difference of each type of bearing is different.
