Description-20MM Bore deep groove ball bearing 6204ZZC3

GJP Bar Code Number: 6935329830356

GJP 20MM Bore Radial deep groove ball bearing 6204ZZC3, which is single row type, and is made of one round shape inner ring, one outer ring, one set of pressed steel cage (rivet type), one set of steel bearing, two metal Z-shields, and 30% to 35% volumn of bearing grease, GJP design our products with hardened chrome steel race and steel ball (HRC59 to 63), prelube type, and more stronger and bigger rivets on mounted steel cage, greasing on both sides of bearings, and in order for better sealing to protect bearing inside from dust, GJP design our deep groove ball bearing with V groove on outer diameter of inner race, and black chamfer on the corner of bearing race.

Deep groove ball bearings are the most widely used type of rolling bearing. It is characterized by low frictional resistance and high rotational speed. It can be used on parts that bear radial load or combined radial and axial loads at the same time, and can also be used on parts that bear axial load, such as low-power motors, Automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

 

Features of deep groove ball bearings:

The deep groove ball bearing has a simple structure and is easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing and can bear combined radial and axial loads. It can also be used to bear pure axial load when the rotational speed is high and the thrust ball bearing is not suitable. Compared with other types of bearings with the same size and size as deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed. However, it is not resistant to impact and is not suitable for bearing heavy loads.

After the deep groove ball bearing is mounted on the shaft, within the axial clearance range of the bearing, the axial displacement of the shaft or the housing can be limited in two directions, so it can be axially positioned in both directions. In addition, this type of bearing also has a certain self-aligning ability. When it is inclined 2′ to 10′ relative to the housing hole, it can still work normally, but it has a certain impact on the bearing life.

Advantages of deep groove ball bearings:

  1. The radial clearance is relatively small, and the radial angular contact bearing can be preloaded and preloaded to eliminate the clearance, and the running accuracy is high;
  2. Most rolling bearings can also bear radial and axial loads, so the bearing combination structure is simple;
  3. Regarding the shaft diameter of the same size, the width of the rolling bearing is smaller than that of the sliding bearing, which can make the axial structure of the machine compact;
  4. Under normal conditions, the efficiency of rolling bearings is comparable to that of hydrodynamic smooth bearings, but higher than that of mixed smooth bearings;
  5. No effective non-ferrous metals are required;
  6. High level of standardization, mass production, low cost;
  7. Less lubricant consumption, easy to seal and easy to maintain;

 

There is C3 clerance design for this bearing, and there are Co, C2, C3, C4 for customer’s choice, and for the size precision, in order to gurantee our bearing to have excellent performance according to different application demands,GJP provide ABEC-1, ABEC-3 quality level (for smaller size, we could produce up to ABEC-5 quality level), 6204ZZC3 could be a 6204-2RS by replacing the Z shield into NBR seal.

GJP designs our radial deep groove ball bearings are widely used on water pump, electric motor, gearbox, instruments, home appliance, engine, transportation car, bicycle, motor, agricultural equipment, construction machine, skating shoes and some sports equipments etc., deep groove ball bearings are one of the most widely used products.
