YDTech® manufacturer of combination needle roller thrust ball bearings(NKIA, NKX)bolt gyr! supplier of combined needle roller ball bearings (NKX, NKX.Z, NKIA, NKIB, NKXR) in china.

combined needle roller bearing is a radial cross section height of the smallest bearing position or one-way positioning. to the heart, such as needle bearings and thrust ball bearings or cylindrical roller bearings used in combination, the scope of its application is expanding.

combined needle roller bearings are mainly used in transmission engineering and machine tools, such as spindle drilling machine, drilling units, will be the central axis, the worm, the first die bearing spindle and similar.

needle roller thrust ball bearings in the NKX series combine a radial needle roller bearing and a thrust ball bearing based. they are able to support single-direction axial loads in addition to radial loads. They also permit relatively high-speed operation

NKX series needle roller thrust ball bearings do not have a cover around the thrust ball bearing. As a result, both the ball and cage assembly and shaft washer can be mounted separately from the rest of the bearing.

NKX .. Z series needle roller /thrust ball bearings are non-separable. They have a stamped steel cover that extends over the shaft washer of the thrust ball bearing. It is firmly attached to the housing washer that is integral to the needle roller bearing outer ring. the cover makes these bearings non-separable. we supplies the thrust ball bearing in this series filled, as standard, with a high-quality grease that has good rust inhibiting properties. The cover, which has no lubrication holes, forms a gap-type seal with the shaft washer to retain the grease in the bearing.
