Supply of Japanese(NSK) original 22318 EAE4 C3 bearings

Folding core roller bearing rear code:
Install the conical hole core roller bearings codenamed K and K30 on the matching compact sleeve and become the rear codenamed K+H and K30+H bearings. This type of bearing can be mounted on a light shaft without an axle shoulder and is suitable for situations where it is necessary to install and disassemble bearings frequently. In order to improve the lubrication performance of the bearings, the bearing outer ring car has a circular oil tank and is drilled with three evenly distributed oil holes, followed by a code W33.
Specific classification and model comparison:
1, tuning roller bearings(20000 CC type)
2, conical hole core roller bearings(20000 CCK type)
3, tuning roller bearings(20000 CC/W33 type)
4, conical hole core roller bearings(200000 CCK/W33 type)
5, installed in the tight sleeve hole core roller bearing(20000 CCK + H0000 type)
6, installed in the tight sleeve hole core roller bearing(20000 CCK/W33 + H0000 type)
Folding different types of tuning roller bearings:
Example: NTN LH series automatic tuning roller bearings
The application of automatic centring bearings is gradually increasing, especially long-life bearings in high temperature environments. For different application environments, NTN engineers developed STJ2 steel, which can extend its service life from room temperature to 250 °C in a large temperature range. This steel is the standard material for the LH series of auto-tuning roller bearings. This bearing is characterized as follows(compared with SUJ2) long-lived bearings in a large temperature range, 3.5 times the lifetime of ordinary materials at room temperature and 30 times the lifetime of ordinary materials at high temperatures(250 °C), preventing surface damage. 7 times anti-peeling ability, 1.4 times anti-abrasion ability, 2.5 times anti-wear ability, dimensional stability at high temperature conditions, almost no size change at 250 °C, strengthening the strength of fracture fatigue, at high temperature and tight match The case, Increase the breakage fatigue life by 2 times. Increase the strength of breakage fatigue by 2 times, simplify the part storage management process, and use a single standard bearing model from room temperature to 250 °C. Automatic tuning roller bearings will gradually be converted to the "LH series".
