Deep Groove Ball Bearings Introduction
        Deep groove ball bearing generally consists a pair of rings, a set of cage, a set of steel balls. Its simple structure and easy usability make itself as the most common and most widely used type of bearings. This kind of bearings is mainly used to bear radial load, moreover, it also could withstand a certain amount of axial load. When increasing the radial clearance of bearing, this kind of bearing has properties of angle contact ball bearing to bear a large axial load within a certain range. After assembled on shaft, the deep groove ball bearing can make the axial displacement limit of the shaft or shell within the bearing's axial range. Meanwhile, when the shell hole and shaft (or IR to OR) are relatively tilted (within 8'-16', according to clearance), the bearing could still work as normal, but the service life is reduced.
   Limit Of Temperature
The allowable operating temperature of deep groove ball bearings depends on:
Dimensional thermal stability / cages for seals / bearing rings and steel balls.
   Sealing element
The allowable operating temperature of the seal depends on the material of the seal:
NBR Butadiene rubber: -40 to +100ºC(-40 to +210F), withstands temperatures up to 120C(250°F) for short periods of time.
FKM: -30ºC to 200C(-20 to 390°F), withstands temperatures up to 230C(445°F) for short periods of time. The highest temperature value of the seal is usually found at the lip of the seal.
   Bearing rings and steel balls
The thermal stability of deep groove ball bearings is at least 120C(250*F), and the highest thermal stability of our bearings is 450C.
   Cage
The operating temperature of steel, stainless steel, brass or PEEK cages is the same as that of bearing rings and steel balls.
   Allowable Speed Of Rotation
The thermal reference mode can be used to quickly assess speed capability. The limit speed is the mechanical limit and should not be exceeded unless the bearing design and application can accommodate higher speeds.
