6234-zz 6234-2rs single row deep groove ball bearings.Bearing cooling axial fastening the bearing outer ring and light metal bearing seat is a tight fit, the heating of the thermal loading on the bearing seat can be avoided with the surface by abrasion. Fuel tank heating bearings, at a certain distance from the bottom should have a net gate, or hook hanging bearings, bearings can not be put on the bottom, to prevent Shen impurities entering the bearing or uneven heating, the tank must have a thermometer, strictly control the oil temperature must not exceed 100 ° C, to prevent tempering effect, reduce the hardness of the rings.
