1) Pre-Code
GS - Thrust cylindrical roller, thrust needle roller bearing ring. Example: GS81107-thrustcylindrical roller bearings 81107 ring.
K - Thrust roller and cage assembly. Example: K81170.
K --- In line with AFBMA standard series Inch tapered roller bearings
with roller and cage assemblies of the inner ring (inner cone) or outside rings (cones). Example: K-09067 - 09000 series tapered roller bearings within the cone.
L - The separation of a single type of bearing inner ring or outer ring. Example: LNU207 - NU207cylindrical roller bearing inner ring.
L30207 - 30207 of tapered roller bearing outer ring.
R - To remove the separation of a single inner or outer bearing. Example: RNU207 - NU207cylindrical roller bearings with roller and cage assembly of the outer ring. R30207 - tapered roller bearings the inner ring and cage assembly.
WS - Thrust cylindrical roller, needle roller thrust shaft washer. Example: WS81107 - cylindrical roller bearing 81107 thrust axis circle.
(2) Post code
If the bearings have several post code in the code, these post-code groups arranged in the following order: (1) interior design,
(2) external design, (3) cage, (4) other features. (1) (2) (3) group and basic post-code-generation
Leave between the number of characters from the half; (2) group in the dust cover and seal the post code is the exception, in front of the post code
Set a hyphen "-";( 4) group home in front of post-code a slash. Slash is also used to isolate the two following
(4) group post code:
a. The first post-code to the end and a second digital code to the rear when the beginning number. Example: 6205/P53/223316.
B. said compression and (/ or) mobile clearance
Range of post-code and then said with a grease type of post code, if the province the slash slightly confusing time. Patients; 6205-2Z/C2L/HT42 (= C2L + HT42).
