This is a kind of practical skill, the familiarity of the product, the machine factory technology sums up the standard size to infer the fuzzy provided by the customerCouplingThe actual model comes for exampleGear coupling，CL型标准外径170毫米为1号，185毫米为2号，220毫米为3号，250毫米为4号290毫米为CL5 coupling。。。。。。GICL型标准外径尺寸240毫米是6号，260毫米为7号，280毫米为8号，315毫米外径的则是GICL9联轴器，GIICL型10号外径是287毫米，11号为325毫米，GIICL12 couplingThe outer diameter is 362 mm, and each product will have its own outer circle (large rotating diameter). It is not difficult for customers to distinguish the outer circle of the product as long as the product is mapped.Gear couplingThe model category, breaking the situation that is as difficult as the appearance, the machinery factory provides you, hoping to help every customer who does not know much about couplings!Welcome to consult company technology 136,4326,3244, XNUMX, XNUMX (Liu's family)!
