<h2>hydraulic floor hinge vvp style gymnastics floor spring/floor hinge in door closers</h2>
function of ground spring:1. can be automatically closed under the action of external force,2. closing speed can be adjusted,3. retention function,4. having door hinge action (the ground spring is also called the earth hinge).
scope of application
The ground spring is used for frameless glass doors, ordinary doors, fire doors and safety doors. But the fire door is only allowed to use the stay spring.
Ground springs are widely used in office buildings, hotels and other comprehensive large buildings, as well as shops, banks and other public places.

JU-80 floor hinge structure and composition
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. |
Spring | High quality alloy spring steel 60Si2Mn or 82B, anti fatigue more than 500 thousand times. | Ordinary spring steel, a thousand times no force |
Hydraulic oil | Sinopec HV46 to the spring, door closer to the low temperature wear oil | Common hydraulic oil or oil recovery |
Cement box | 1.2-1.5 cold rolled sheet | Scrap iron sheet |
Central support arm | High quality steel forging (compact, wear-resistant) | Ordinary cast steel, easy deformation |
