4 Classification and code method
4.1 Classification
JB/T 7358-94
Non-grinding ball bearings are divided into 9 categories according to their process characteristics, structural characteristics and load direction. See the table. Table 1 Types and codes
Machine-made ring bearings
Fully stamped ring bearings
Plastic ring bearings
Machine-made and stamped ring bearings
Metal and plastic ring bearings
1 Double and half outer ring bearings
Thrust bearings
Double-row bearings
Universal ball bearings
Each type of bearing can be derived from several variants, such as: Machine-made ring bearings
Inner ring variants
Type code
Basic structure
Full complement ball bearings
Bearings with cages
Full complement ball point contact bearings with outer covers
Full complement ball bearings with stamped outer rings with outer covers
With outer covers Stamped outer ring angular contact ball bearing
Plastic outer ring bearing with cage
Full complement ball bearing with double and half outer ring with outer cover
Flat-bottom thrust ball bearing with outer cover
Full complement double row ball bearing
Stamped outer shell flange type universal ball support
Inner ring widened on one side or both sides
Inner ring opening
Inner ring inner hole is elliptical
Inner ring inner hole is hexagonal
Shaft replaces inner ring
Threaded shaft replaces inner ring
Outer ring outer diameter is spherical
External variant:
Outer ring outer diameter is circular slide groove
Outer ring has flange
The basic structure and variant structure of various bearings are shown in Appendix A. 4.2 Code The non-spherical auxiliary bearing code consists of three sections: the first section is the type code, the second section is the basic size code, and the third section is the supplementary code. 4.2.1 Type code The type code is represented by the letter U or 12 letters before U, as shown in Table 1. 4.2.2 Basic size code The basic size code of general bearings is represented by four Arabic numerals. The first two digits from the left represent the outer diameter of the bearing (in millimeters), and the last four digits represent the inner diameter (d) in millimeters (no unit is marked). 58
Example: CU
JB/T 7358--94
Inner diameter is 8mm)
Outer diameter is 22 (mm)
Machined ring steel cage non-grinding ball bearing
b. The basic size of the Wanjian ball bearing is expressed in meters by the diameter of the main ball (rounded according to the digital rounding rules). Example: WU13 represents a hall-type ball bearing with a main ball diameter of 12.7 mm. 4.2.3 See Table 2 for supplementary codes.
Supplementary codes
S, C
WBI, WB
Using plastic cage
Chromium steel bearing (applicable to U type)
Bearing surface with sealing ring
Bearing with sealing cabinet on both sides
Bearing--with dust cover
Bearing with dust cover on both sides
With outer cover, with flange outer cover
Bearing surface with felt seal
Bearing one end closed
Shaft replaces inner ring
Inner ring surface Widened, inner ring with widened sides
Outer ring has an edge
Outer ring is spherical
Inner ring has a notch
Spherical outer ring
Inner ring has a hexagonal hole
Inner ring inner diameter is an eccentric hole
The bolt shaft replaces the inner ring
The bearing is installed on the plastic wheel hoop
The structure changes greatly, and the above codes cannot represent it. Note: When it has multiple of the above characteristics at the same time, its supplementary codes are arranged in order from top to bottom. Example of code: PRU
