『壹』 內徑二十毫米外徑52毫米的向心球軸承的型號
深溝球軸承6304 內徑20外徑52寬度15
調心球軸承1304 內徑20外徑52寬度15
調心球軸承2304 內徑20外徑52寬度21
『貳』 304與204的軸承有什麼區別
這個軸承當然是有區別的呀。也就是說，304和204，他的鋼材的質量是不同的。也就是說，它們的材質也是不同的。304可能是密度會更高一些，更結實耐用。
『叄』 外徑52，的軸承內孔多大
外徑52，對應的內徑有好幾種，內徑20，外徑52，寬度15有深溝球軸承6304，調心球軸承1304，內徑25，外徑52，寬度15有深溝球軸承6205，圓柱滾子軸承NU205，還有內徑是40，外徑52，寬度7，對應深溝球軸承61808，等等還有很多種，具體得看需要哪個類別的，以及另外兩個尺寸的范圍，才能最終確定具體型號。
『肆』 內徑20外徑52的軸承是什麼型號
6304深溝球軸承，7304單列角接觸球軸承，3304雙列角接觸球軸承，1304自調心球軸承，NU304和NU2304單列圓柱滾子軸承，等等。
