● Introduction
Single row deep groove ball bearings with snap ring consists of an inner ring, an outer ring, a steel ball, a cage and a sealing ring. The outer wall of the outer ring is recessed inward to form a stop groove, and an open elastic stop moving ring. The ratio of the depth of the retaining groove to the thickness of the outer ring is 0.2 to 0.3. The standard code for deep groove ball bearings with snap grooves is N, and the code for deep groove bearings with snap grooves and snap rings is NR. In addition, there are ZN, ZNR and other structures. The snap ring of the bearing can prevent the axial movement of the bearing, simplify the structure of the bearing seat and reduce the size of the bearing, so the single row deep groove ball bearings with snap ring is more economical, more convenient and widely used.
Snap ring bearings mainly bears radial load, and is generally used in parts with small axial load such as automobiles and tractors.
● Bearing Series
The types of the bearings include 6000NR series, 6200NR series, 6300NR series, 6400NR series, 61800NR series, 61900NR series and 16000NR series.

● Production Details
◆ Turning of deep groove ball bearing combined cage
The cage is composed of two halves and connected by rivets. There are two structures, with and without a stop. The processing process is: rough turning forming (inner diameter, outer diameter, end face, cutting) → flat end face, boring → turning stop (matching) → drilling rivet hole (matching pin drawing matching line) → drilling (expanding) pocket → finish turning the inner diameter, outer diameter, end face → remove the thorn → draw the matching line, remove the pin, clean → clean, oil, and package.
When drilling rivet holes, use a plug gauge to measure the diameter of the rivet hole, use a caliper to measure (or visually measure) the center diameter and skewness of the rivet hole, and use a sample plate to measure the diameter and depth of the countersunk hole. When drilling the ball pocket, if the matching pin is too loose, it is easy to cause the two half cages to be dislocated.
◆ Vickers hardness (HV) testing
According to the standard of bearing hardness testing method, the quenching and tempering hardness of rings with an end face width of less than 2mm, steel balls with a diameter of 1.6~4.76mm, and rollers and needles with a diameter of 1~5mm shall be tested with a Vickers hardness tester.
The Vickers hardness testing method is to press a regular quadrangular pyramid diamond indenter with a relative angle of 136 into the surface of the sample with a selected test force (P). After the specified time, remove the test force, measure the two diagonal lengths (dd) of the indentation with a reading microscope (installed on the instrument) and calculate the average value d (mm). Based on this, the indentation surface area F is calculated, and the value of the average pressure P/F is obtained, this is Vickers hardness value (HV), the unit is N/mm.
● Common Faults and Causes of Bearings
The failure forms of rolling bearings include difficulty in bearing rotation and heat. abnormal noise in bearing operation. vibration of bearings. peeling and cracking of inner seat coils. peeling and cracking of outer races. indentation of bearing raceways and rolling elements. The reasons for the failure include careless inspection before assembly, improper assembly, such as improper coordination, improper assembly method, improper temperature control during assembly, improper alignment of the coupling, and poor lubrication, unbalanced rotor, untimely inspection and replacement.
