634ZZ Micro Deep Groove Ball Bearing 4*16*5 mm

634ZZ Micro Deep Groove Ball Bearing 4*16*5 mm

  It is the most widely used type of rolling bearing. Its characteristics are low frictional resistance, high rotational speed, and can be used for bearing radial loads or combined radial and axial loads, as well as for bearing axial loads, such as low-power electric motors, car and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.
It mainly bears radial loads and can also bear both radial and axial loads simultaneously. When it only bears radial load, the contact angle is zero. When deep groove ball bearings have large radial clearance, they have the performance of angular contact bearings and can withstand large axial loads. The friction coefficient of deep groove ball bearings is very small, and the limit speed is also very high.
The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls, and a retaining structure.
The type code for single row deep groove ball bearings is 6, and the code for double row deep groove ball bearings is 4. Its simple structure and convenient use make it the most widely produced and widely used type of bearing.
