.SL-HYDNUT系列拆卸軸承液壓螺母,拆卸用液壓螺母,拆卸液壓螺母主要用于連接件的無縫連接，其工作原理是利用超高壓油在軸上產生一個推力和軸套上產生一個張力，使軸和軸套受力均勻地連接在一起。
.有軸向和徑向注油兩種方式;
.壓力均勻分布于壓環;
.標準工作壓力0一150Mpa;
使用范圍：
.安裝及拆卸軸承;可根據客戶要求訂做，用于造紙機械、水泥機械、船舶冶金等領域，安裝及拆卸螺旋槳、舵瓦等;
.拆卸高壓的接臺面，如火車輪、聯軸器、飛輪及齒輪等;
*SL一HYDNUT液壓螺母適用于安裝和拆卸內徑50mm或以上的回錐孔軸承。這種方法比機械式的方法更簡便和節省時間。
*SL一HYDNU下液壓螺母可以提供公制或英制螺紋的設計，另有無螺紋孔的螺母以用于一些較特殊的情況。
*SL-HYDNUT液壓螺母與裝有電子壓力表的液壓泵和深度千分尺共同使用時，可以充分發揮出SOLY液壓推動法(SOLY Drive-upMethod)簡便和精確的優點。
.在錐形軸或套筒上安裝和拆卸軸承，通常是既困難又耗時的工程。使用SOLY索力液壓螺母，可以減少這類問題。油泵輸入螺母中推動活塞的力量，足夠安裝和拆卸軸承毫不費力、既準確又安全。所有液壓螺母附送一個快速接頭偶聯器，以連接液壓泵。
.本公司還采用德國技術生產SL一HYDNUT50-1000系列液壓螺母.如有特殊需要與SOLY工程師咨詢。
