Tungsten bars, rods, profiles and profiles plates, sheets, strip and foil of a deeper level of processing products export tariffs, so the 5% export tax rebate policy will continue. It can be understood, at least for now, for this type of tungsten production and exports, the country is still allowed, and even encouraged.

Thrust needle roller bearings | thrust cylindrical roller bearings | thrust ball bearings
Thrust bearing with needle or cylindrical roller or ball thrust cage assemblies and thrust washers components. Needle roller and cylindrical roller by
To Tungsten eletrode holding and guidance. DF with different series of thrust bearing washers are used together, can be equipped for the bearing
Set offers many different combinations. As the use of high-precision cylindrical roller (needle) increased contact length makes this bearing in
Very little space available under a high load capacity and high rigidity. Another advantage is that if adjacent parts raceway surface is adapted for
Can be omitted when washer, can compact design, DF thrust needle roller bearings and cylindrical roller bearings with thrust needle roller and cylindrical roller
The cylindrical surface of the surface modification can reduce the edge stress, improve life.
Thrust needle roller and cage assemblies AXK
Thrust needle roller and cage assemblies are the main components of the thrust needle roller bearings. Arranged by the radial needle roller bag holder and guidance.
The holder having a specific cross-sectional shape, is formed of hardened steel. Small cage with industrial plastics.
Precision needle roller diameter grouping tolerance of 0.002mm, to ensure that the load is evenly distributed. Thrust needle roller and cage assemblies using axis guide
. Thus, even if the guide surface at high speed can be obtained relatively low circumferential speeds.
If the adjacent raceway surface is designed to save space-saving washer will receive a special support. If this program can not be implemented
When there is sufficient support in the conditions, the use of thin-walled steel washers AS Series also enables a compact design.
Thrust cylindrical roller bearings 811,812,893,874,894
This bearing is a thrust cylindrical roller and cage assembly, a bearing locating ring GS and a WS-axis positioning components. 893
, 874 and 894 series cylindrical roller thrust bearings can be used for higher loads.
DF thrust cylindrical roller bearing cage by high quality steel stamping, but also by industrial plastics, light metals and brass manufacturing
As users request based on the environment.
Thrust Ball Bearings
Retainer material is divided into stainless steel and copper, thrust ball bearings are separable, the contact angle of 90, can be installed separately,
Only carry axial load. Limit ... thrust ball bearings Thrust ball bearings can withstand axial load, thrust
Ball bearings can withstand axial load, spherical seat thrust ball bearings with aligning properties, can eliminate the impact of installation errors
