1. The front code has no code when it is marked with SAE52100 high chromium bearing steel.
S-AISI440C stainless steel.
M- M50 tool steel.
2. Post code (1) When the type has no code, it indicates the ball bearing
B- can not leave the inner ring angle touch bearing
H- Do not leave the outer ring angle touch bearing (2) Seal and dustproof without code indicating open bearing
F- single-sided touch seal
FF-double-sided touch seal
S- single-sided dust cover
SS-double-sided dust cover
Y- single-sided pressure seal
YY- double-sided pressure seal (3) cage and its data without code when specifying the specific bearing scale specification cage
W- double half; metal stamping; light claws
TA-one-piece side-mounted; phenolic
T- double half riveting; aluminum cladding phenolic
TMT- one-piece side-mounted; nylon molded (4) special function
X50- inch; small steel ball
X200- tight seal between the outer ring groove and the dust cover
X204- User part household; marked by electric erosion on the outer ring of the bearing
X205- full ball type (refers to H type)
X216- No dust cover and steel expansion ring (5) Radial oil gap digitally indicates the radial oil gap size of the radial ball bearing. Regarding the angular touch ball bearing; no code indicates the specification touch angle.
Note: When the front of the bearing type ends with a number; then the letter "K" is used between the radial oil gap and the number; avoid mixing.
(6) Torque test Most miniature bearings and external bearings have low torque characteristics. Various different torque levels are indicated by the following codes:
V- ensures low torque levels
VL- ensures extremely low torque levels
VT- provides a practical torque diagram for each set of bearings with VL torque levels. (7) Paired devices and preloaded letter codes indicate pairs of devices. For example, the letters are followed by a numeric code; the numbers indicate the uniform preload in pounds. Many The word indicates the specification preload.
D-paired device
DB- back to back device
DF- face-to-face device
DT-series device
DD- three sets of series devices
The standard preload of H-shaped angular touch ball bearings is light; medium; heavy; marked with the following letters:
L- light preload
M- medium preload
H-heavy preload (8) Radial runout is indicated in the bearing type as long as the special radial runout is indicated; and is indicated by the letter E.
E- Radial runout is less than the standard civil service; when E is followed by the letter R; the highest point of the radial runout is marked on the bearing by the following code.
ER- inner ring radial runout highest point.
ER1 The outer ring has the highest point of radial runout.
ER2-inner; the outer ring has the highest point of radial runout.
(9) Bearings with grouped inner and outer diameter groups; marked with the letter C. The codes used are as follows:
The C-inner and outside diameter public service scales are grouped in increments of 0.0001 in; and the group is marked on the package.
CXO- Internal Diameter Scale Public Service Group
COX- OD scale public service grouping
C44- OD and OD scales are grouped by 0.00005 in
