NTN bearing suffix code expresses


30th January 2010 Bearing Technology 0 Comments

The suffix code of NTN bearing has shown NTN bearing contacts the angle, keeps a form, dustproof form, internal backlash, the precision,etc.. U.i.:

Exposed to the angle serial number
To the ball bearing of heart thrust:

A : 30 degrees of standard angles
B: 40 degrees of standard angles
C: 15 degrees of standard angles
Sub bearing of the taper roller

B : Exposed to the angle and greater than 10 degree to 17 degree ‘ Including
C: Exposed to the angle and greater than 17 degree to 24 degree ‘ Including
D: Exposed to the angle and greater than 24 degree to 32 degree ‘ Including
Inside changes the serial number
U: Inside is exchanged, NTN taper rolls the sub bearing
R: Is not exchanged by the inside, the taper rolls the sub bearing
ST: Low torsion, taper get away sub bearing
HT: High axial load, cylinder bearing
Keep a serial number
L1: The high strength car makes brass to keep the shelf
F1: The car makes the steel of carbon to keep the shelf
G1: The high strength brass of square hole does not have rivet that keep the shelf
G2: The pin type keeps the shelf
J: Pressing the stencil plate keeps the shelf
T2: The resin keeps the shelf
Sealed lid /Overlay the serial number dustproofly
LLB: Rubber seal enclose ‘ Do not keep in touch
LLU: Rubber seal enclose ‘ Keep in touch
LLH: Rubber seal enclose ‘ Low torsion
ZZ: Sealed lid of stencil plate
The outside alters the serial number
K: The internal diameter of the taper, the standard rate 1: 12
K30: The internal diameter of the taper, the standard rate 1: 30
N: Stop moving the trough
NR: Stop working up the ring
D: There are oil holes
D1: There are oil grooves and oil holes
The pair disposes the serial number
DB: Arrange back-to-back
DF: Arrange face-to-face
DT: Stand side by side and arrange
D2: Bearing of the pair
G: Freedom association
a: The tape separates and enclosesa: Show that separates the standard size that encloses
Internal backlash /Press in advance
C2: The backlash is smaller than normally
CN : Normal backlash
C3: The backlash is greater than normally
C4: The backlash is greater than C3
C5: The backlash is greater than C4
CM: The electrical machinery uses the backlash
/GL: It is pressed in advance that light
/GN: Press ordinarily in advance
/GM: China presses in advance
/GH: It is pressed in advance that heavy
Serial number of the precision
P6: JIS 6 grades
P5: JIS 5 grades
P4: JIS 4 grades
P2: JIS 2 grades
2: ABMA 2 grades
3: ABMA 3 grades
0: ABMA 0 grades
00: ABMA 00 grades
Lubricant serial number
/2A: Shell Alvania 2 oil
/3A: Shell Alvania 3 oil
/8A: Shell Alvania EP2 oil
/5k: MULTEMP SRL
/LX11: Barierta Jfe552
/LP03: Heat-curable the plastics ‘ Solid oil
