1)ZARN0000TN型 普通型滾針和雙向推力圓柱滾子組合軸承,該軸承中圈同時(shí)作為向心滾針軸承外圈。內(nèi)圈的寬度同中圈和推力滾子相配和以便當(dāng)擰緊鎖緊螺母時(shí)能得到預(yù)定的軸向預(yù)負(fù)荷。
2)ZARN0000LTN型 寬度加長(zhǎng)型,該型式軸承一端推力墊圈為加長(zhǎng)型,外部為階梯形。該軸承用于軸承定位圈的軸向支撐不夠之處,或者用在由于受到軸承配置空間的限制而無法再在標(biāo)準(zhǔn)軸(定位)圈的徑面上使用轉(zhuǎn)動(dòng)油封之處。
滾針和推力圓柱滾子組合軸承相當(dāng)于一套雙向推力圓柱滾子軸承和一套滾針軸承,能承受軸向、和徑向聯(lián)合載荷,而軸向尺寸較兩種軸承相加要小得多,結(jié)構(gòu)緊湊,適用于軸向、徑向尺寸受限制的部件中。
