隨著機(jī)床裝備技術(shù)的發(fā)展，高精度、高效率成為當(dāng)前機(jī)械行業(yè)的重要技術(shù)特點(diǎn)，機(jī)床滾珠絲杠支承軸承逐漸放棄傳統(tǒng)的配對角接觸球的結(jié)構(gòu)模式，轉(zhuǎn)而采用滾針/推力圓柱滾子軸承的結(jié)構(gòu)形式。
滾針/推力圓柱滾子軸承采用外圈加厚的滾針軸承和兩列推力圓柱滾子軸承的組合結(jié)構(gòu)，可以承受更大的徑向/軸向載荷，具備更高的徑向/軸向剛性，同時(shí)該系列軸承軸向跳動精度可達(dá)1μm，特別符合當(dāng)前機(jī)械加工行業(yè)所要求的高精度，高承載，高效率的特點(diǎn)。
產(chǎn)品特性
滾針/推力圓柱滾子軸承包括一個(gè)加厚的外圈、滾針保持器組件、滾針內(nèi)圈、兩個(gè)推力圓柱滾子保持器組件和兩個(gè)推理軸圈，相當(dāng)于一套滾針軸承和兩套推力圓柱滾子軸承的組合軸承，兩個(gè)推力圓柱滾子軸承中心和滾針軸承中心重合。
滾針/推力圓柱滾子軸承可以承受兩個(gè)方向的軸向力、徑向力和傾覆力矩。
滾針/推力圓柱滾子軸承按照外圈安裝方式的差異可以分為螺栓安裝和非螺栓安裝兩個(gè)類型系列。
