Product Description
Deep groove ball bearings are the most widely used bearing type with a broad dimension range and extensive varieties. It can accommodate radial load, axial load and combined load. The advantage of this kind of bearings is which enables rotational speeds with low noise and low friction coefficient. It's applied in automobile industry and machinery manufacturing etc.
application
Deep Groove Ball Bearing can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, engineering machinery, roller skates, yoyo balls, etc.

The bearing load of Deep Groove Ball Bearing is too small during operation, which will cause sliding between the ball and the raceway and become the cause of scratches. In particular, large Deep Groove Ball Bearing with heavy balls and cages have this tendency. In many cases, bearings may rust, and there are many reasons for bearing corrosion. The most common factors in our daily life are the following:
1) Due to poor sealing device, it is invaded by moisture, dirt, etc;
2) The bearings have been unused for a long time, exceeding the rust prevention period and lacking maintenance.
3) The surface roughness of the metal is relatively high;
4) Contact with corrosive chemical media, poor cleaning of bearings, surface contamination with dirt, or contact with bearings with sweaty hands, failure to package or install bearings in a timely manner after cleaning, long-term exposure to air, invasion and contamination by air moisture;
5) Environmental temperature and humidity, and exposure to various environmental media; The rust inhibitor fails or the quality does not meet the requiremenT.
Installation method
1.press fit: the inner ring of the bearing is tightly matched with the shaft. When the outer ring is loosely matched with the bearing seat hole, press the bearing onto the shaft with a press machine, and then install the shaft and the bearing into the bearing seat hole together. When pressing, pad an assembly sleeve made of soft metal material (copper or soft steel) on the end face of the bearing inner ring. The outer ring of the bearing is tightly matched with the bearing seat hole. When the inner ring is loosely matched with the shaft, The bearing can be pressed into the bearing seat hole first, and the outer diameter of the assembly sleeve should be slightly smaller than the diameter of the seat hole. If the bearing ring is tightly matched with the shaft and seat hole, the installation of the inner and outer rings should simultaneously press into the shaft and seat hole. The structure of the assembly sleeve should be able to simultaneously press the end faces of the bearing inner and outer rings.
2.heating fit: by heating the bearing or bearing seat, use thermal expansion to change the tight fit into loose fit. It is a common and labor-saving installation method. This method is suitable for the installation of bearings with large interference. Before hot installation, put the bearing or the ring of separable bearing into the oil tank and heat it evenly for 80-100 ºC, then take it out of the oil and install it on the shaft as soon as possible, In order to prevent the inner ring end face from not fitting tightly with the shaft shoulder after cooling, the bearing can be tightened axially after cooling. When the outer ring of the bearing fits tightly with the bearing seat made of light metal, the hot assembly method of heating the bearing seat can be used to avoid scratches on the fitting surface. When heating bearings with oil tanks, there should be a grid at a certain distance from the bottom of the box, or a hook should be used to hang the bearing. The bearing should not be placed on the bottom of the box to prevent impurities from entering the bearing or uneven heating. There must be a thermometer in the oil tank, and the oil temperature must be strictly controlled to not exceed 100 ºC to prevent tempering effect and reduce the hardness of the ring.
