備註 (note)：
1.EK05~EK08 C7級使用6字頭軸承，軸向需輕負荷，間隙約0.05~0.1mm.(欲訂此規格請先洽詢技術資料)
(Using deep groove ball bearings for EK05 to EK08 C7 types Support Units , Which only be applied to light load , and Max. axial clearance is around 0.05~0.1mm.)
2.EK10~EK20 C7級使用之7字頭軸承無預壓處理，,軸向最大間隙 0.018mm
(Using angular contact ball bearings without preload for EK10 to EK20 C7 types Support Units , and Max. axial clearance is 0.018mm.)
3. C5級使用之軸承經預壓處理，軸向0間隙
(Bearings make Preload for C5 type support units , and Axial clearance is 0 mm..)
4.軸承皆採用日系品牌大廠，採DF組裝，最適宜滾珠螺桿使用
(All of bearings use Japan's brand bearings,Assembly by DF way. The most suitable way for ballscrew use.)
