a)定位精度高。滾動直線導(dǎo)軌的運動借助鋼球滾動實現(xiàn)，導(dǎo)軌副摩擦阻力小，動靜摩擦阻力差值小，低速時不易產(chǎn)生爬行。重復(fù)定位精度高，適合作頻繁啟動或換向的運動部件?？蓪C(jī)床定位精度設(shè)定到超微米級。同時根據(jù)需要，適當(dāng)增加預(yù)載荷，確保鋼球不發(fā)生滑動，實現(xiàn)平穩(wěn)運動，減小了運動的沖擊和振動。 b)磨損小。對于滑動導(dǎo)軌面的流體潤滑，由于油膜的浮動，產(chǎn)生的運動精度誤差是無法避免的。在絕大多數(shù)情況***體潤滑只限于邊界區(qū)域，由金屬接觸而產(chǎn)生的直接摩擦是無法避免的，在這種摩擦中，大量的能量以摩擦損耗被浪費掉了。與之相反，滾動接觸由于摩擦耗能小，滾動面的摩擦損耗也相應(yīng)減少，故能使?jié)L動直線導(dǎo)軌系統(tǒng)長期處于高精度狀態(tài)。同時，由于使用潤滑油也很少，這使得在機(jī)床的潤滑系統(tǒng)設(shè)計及使用維護(hù)方面都變的非常容易。

style="text-indent:25px">直線導(dǎo)軌的精度等級：一般直線導(dǎo)軌副的精度分為普通級、高級、精密級、超精密級和超高精密級五種。主要檢測指標(biāo)一般有三個，一是滑塊C面對滑軌A面的平行度，二是滑塊D面對滑軌B面的平行度，三是行走平行度，所謂行走平行度是指將直線導(dǎo)軌固定在基準(zhǔn)座平面上，使滑塊沿行程行走時，導(dǎo)軌與滑塊基準(zhǔn)面之間的平行度誤差?！? 直線導(dǎo)軌的預(yù)壓力：所謂預(yù)壓力是預(yù)先給予鋼珠負(fù)荷力，利用鋼珠與珠道之間負(fù)向間隙給予預(yù)壓，這樣能夠提高直線導(dǎo)軌的剛性和消除間隙?！?按照預(yù)壓力的大小可以分為不同的預(yù)壓等級。預(yù)壓力從有間隙到0.13C不等。C值為動額定負(fù)荷。在選用的過程中可以根據(jù)計算結(jié)果隨時返回到前面的步驟進(jìn)行重新選擇和設(shè)定。計算滑塊負(fù)荷時要確認(rèn)選用的直線導(dǎo)軌靜安全系數(shù)應(yīng)該超過推薦表中所列值?！?如果所選用的直線導(dǎo)軌副剛性不足，可以提高預(yù)壓力，加大選用尺寸或增加滑塊數(shù)來提高剛性。靜安全系數(shù)定義為靜額定負(fù)荷與工作負(fù)荷的比值。值得提到的是兩列歌德式結(jié)構(gòu)的直線導(dǎo)軌副能承受各個方向的力和力矩，在輕負(fù)載或中負(fù)載應(yīng)用場合較多，尤其在側(cè)向力負(fù)載較大時。</p><div
