Q1:How To Design The Size Of The Bearing End Cover?

A:Bearing chamber size +0.01-0.026. External stop mouth -0.03-0.05.

Q2:The Difference Between Self-aligning Ball Bearing Type And Self-aligning Roller Bearing?

A:The self-aligning ball bearing has two columns of steel balls, two raceways in the inner ring, and the raceway in the outer ring is of the inner spherical type, which has the performance of automatic self-aligning. It can automatically compensate the coaxiality error caused by the deflection of the shaft and the deformation of the shell, and is suitable for the parts where the bearing hole cannot guarantee the coaxiality. This kind of bearing mainly bears radial load, while bearing radial load, can also bear a small amount of axial load, usually not used to bear pure axial load, such as bear pure axial load, only a column of steel ball force
Self-aligning roller bearing has two rows of rollers, which are mainly used to bear radial load, but also can bear axial load in any direction. This kind of bearing has high radial load capacity, especially suitable for heavy load or vibration load work, but can not bear pure axial load; Good aligning performance, can compensate coaxiality error.

Q3:Bearing Type And The Relationship Between Inner And Outer Diameter

A:The relationship between bearing type and inner and outer diameter is as follows:
The national standard stipulates that the rolling bearing code is expressed in 7 Arabic numerals: ⑦⑥⑤④③②①, the meaning of each number is as follows:
1, ②① indicates the inner diameter of the bearing.
Where: 00-10mm; 01-12mm; 02-15mm; 03-17mm; After 04: Code x5= bearing inner diameter. For example, the code name is 06, the inner diameter of the bearing is 6×5=30mm.
2, ③ Bearing diameter series: 1- extra light; 2- Light; 3- medium; 4- Heavy.
3, ④ Bearing type (the common angular contact ball bearing is 6).
4, ⑥⑤ bearing structure characteristics.
5, ⑦ bearing width series.
The normal width has no special structural requirements of the bearing, ⑦⑥⑤ are 0, in the code need not write. Example 6120 bearing: special light series angular contact ball bearings, bearing inner diameter of 100mm.

Q4:What Does Needle Roller Bearing Type NK Mean?

A:Needle roller bearing NA, NKI type with outer ring double flange (or double lock ring) and cage type NA, NKI type bearing without inner ring is RNA, NK type needle roller bearing

Q5:What Does The Suffix C3 Of Bearing Model 6217C3 Mean?

A: C3: Is the bearing clearance code.
One ring of the bearing is fixed, and the other ring is moved up and down or left and right. The amount of movement is called the clearance of the bearing. The amount of up and down movement is called radial internal clearance, and the amount of left and right movement is called axial clearance.
The amount of movement is coded. Bearing clearance (from small to large) code is:
C2 / C0 or CN/C3 / C4 / C5
(The above is the radial internal clearance, and the axial clearance can be calculated from the radial clearance)
C0 or CN is the standard clearance, the reaction in the bearing model is generally omitted, not marked. Those smaller than the standard gaps are called small gaps (C2), and those larger than the standard gaps are called large gaps (C3, C4, C5).

Q6:Can Tapered Roller Bearings Be Connected In Series

A:Tapered roller bearings are usually of the separation type, that is, the tapered inner ring assembly consisting of the inner ring with the roller and the cage assembly can be installed separately from the tapered outer ring (outer ring). Cannot be connected in series.

Q7:What Is The Difference Between Tapered Roller Bearing Symbols U And V

A: At the end of the rolling bearing model, there may be letters “u” or “V” and other letters, which are supplementary code names of the bearing model, indicating the code names marked in accordance with the regulations when the bearing material, structural design and technical conditions change.
U — indicates that the clearance of the bearing is different from the current standard.
V — indicates that the ferrule and rolling body are made of plastic, a material not commonly used.
