深溝球軸承是滾動軸承中最為普遍的一種類型。基本型的深溝球軸承有一個外圈、一個內圈、一組鋼球和一組保持架構成。深溝球軸承類型代號為6。 深溝球軸承主要用于承受純徑向載荷，也可同時承受徑向載荷和軸向載荷。當其僅承受純徑向載荷時，接觸角為零。當深溝球軸承具有較大的徑向游隙時，即具有角接觸軸承的性能，可承受較大的軸向載荷。深溝球軸承的摩擦系數很小，極限轉速也很高，特別是在軸向載荷很大的高速運轉工況下，深溝球軸承比推力球軸承更有優(yōu)越性。 深溝球軸承結構簡單，與別的類型相比易于達到較高的制造精度，所以便于成系列大批量生產，制造成本也較低，使用極為普遍。深溝球軸承除基本型外，還有各種變型結構，如：帶防塵蓋的深溝球軸承；帶橡膠密封圈的深溝球軸承；有止動槽的深溝球軸承；有裝球缺口的大載荷容量的深溝球軸承；雙列深溝球軸承。 1、帶防塵蓋的深溝球軸承 標準的帶防塵蓋深溝球軸承Z型和2Z型兩種，一面帶防塵蓋的是Z型，兩面帶防塵蓋的是2Z型。 帶防塵蓋的軸承用在單獨潤滑較為困難、安置潤滑油路和檢查情況不方便的條件下，軸承在制造廠已填注了定量、定牌號的防銹、潤滑兩用鋰基脂。每套軸承注入的脂量通常是軸承內有效空間的1/4～1/3，也可根據用戶要求增減用脂量。注入的潤滑脂通常能保證軸承在-40～+120℃的工況下運轉。如果用戶對軸承還有更高的要求，也可根據情況填注其他性能、牌號的潤滑脂。帶防塵蓋的軸承經過注脂就可長期有效的工作，不需在使用期間再添加潤滑脂。 帶防塵蓋軸承多用于中小型發(fā)電機、電動機的轉子兩端、汽車、拖拉機、空調器、風扇等處，以及對軸承的噪聲振動有特別要求的場合。 2、帶密封圈的深溝球軸承 標準型帶密封圈的深溝球軸承有接觸式密封軸承RS型（一面密封）、2RS型（兩面密封）和非接觸式密封軸承RZ型（一面密封）、2RZ型（兩面密封）。 帶密封圈的軸承的性能、添脂和用途與帶防塵蓋軸承基本相同。不同的是帶防塵蓋軸承的防塵蓋與內圈之間有較大間隙，而非接觸式密封圈軸承的密封唇與內圈之間間隙很小，接觸式密封圈軸承的密封唇與內圈之間沒有間隙，密封效果好，但摩擦有所增加。 有低噪聲要求的場合，多用60和62系列的較小尺寸的深溝球軸承。不論開式軸承、帶防塵蓋型或帶密封圈型的軸承，都可在訂貨時提出低噪聲、低振動的要求。在我國JB（機械行業(yè)標準）中規(guī)定了V1、V2、V3各振動等級的低、中、高三個頻帶的振動允許值。在SKF公司還可提供超低噪聲的軸承，這種軸承標有后置代號QE5。 3、有止動槽的和帶止動環(huán)的深溝球軸承 標準型的有止動槽的深溝球軸承，后置代號為N，有止動槽并帶止動環(huán)的軸承后置代號為NR，此外還有ZN，ZNR等結構變型。 有止動槽和帶止動環(huán)的軸承除具備深溝球軸承可承受徑向載荷的功能外，止動環(huán)可限制軸承軸向位移，簡化軸承座的軸向結構和縮小軸向尺寸。 有止動槽和止動環(huán)的軸承多用于汽車、拖拉機等軸向載荷不大的工作部位。1，開式軸承是指不帶任何密封蓋的軸承。 2，同一個尺寸的軸承，客戶可以選擇不同的材料，等級。 3，以下尺寸為按國際標準的軸承的基本尺寸，如客戶有不同的要求，我們可以定做。 4，相同的軸承有各種不同的代號和叫法，請確認自己需要的軸承的尺寸。
