Kaida floor spring and Inferior product material contrast
|Accessories name||Kaida products||Inferior product|
|Panel||304 stainless steel, thickness 1.2mm.||Usually used 201, 202, 430 stainless steel or lower performance materials, easy to rust; some product panel thickness of only 0.8mm, after the deformation of the deformation.|
|Cam||Alloy structural steel 20Cr||Ordinary 45 steel|
|Floor spring shell||HT220 gray cast iron (using large scale special equipment for processing, in order to ensure the dimensional accuracy and surface quality).||HT150 the following gray cast iron, tensile strength is low|
|Rotary sealing ring||To ensure the service life of the imported products.||Common seal ring|
|Bearing and roller||GCr15 bearing steel, the larger size of the use of G20CrNiMo. Cover plate with 61805 bearing||Ordinary steel, hardness and contact fatigue strength is low, the impact of the use of performance and life expectancy.|
