美國MOUKEN滾針推力軸承
美國MOUKEN滾針推力軸承的軸向作用分離型軸承也需要整體高度更低的單方向。
滾針推力軸承只能接受軸向載荷和是不敏感的沖擊負(fù)荷。
因此，滾針止推軸承提供具有zui小的軸向空間需求非常剛性的推力軸承結(jié)構(gòu)。
推力軸承的幾個變化
可考慮在可用性鏟依賴，運(yùn)行精度精度或指導(dǎo)的要求。
作為圓柱滾子推力軸承，滾針推力軸承是如此經(jīng)受增加的滑動摩擦。
為了避免過度的滑動摩擦的負(fù)面影響，滾針推力軸承只適合于低速的應(yīng)用程序。
滾針推力軸承要求zui小軸向載荷對于其*功能。

Needle Roller Thrust Bearings Needle roller thrust bearings are single direction acting separable axial bearings that require less overall height. Needle roller thrust bearings accept axial loads only and are insensitive to shock loading. Thus, needle roller thrust bearings provide a very rigid thrust bearing arrangement with minimal axial space requirement. Several variations of thrust bearings are available for consideration dependant upon the spade availability, running accuracy precision, or guidance requirements. As for cylindrical roller thrust bearings, the needle roller thrust bearings are also subject to increased sliding friction. In order to avoid the negative effects of excessive sliding friction, needle roller thrust bearings are only suitable for low speed applications . Needle roller thrust bearings require minimum axial loads for their optimum function.
