The cups will not slide or fall off when it adsorb vertically. The seal of cups are good, and no air release from the gapģ. The diameter will not changed when pull the cups.Ģ. Flat - suitable for glass, metal sheets and cardboard. This calculation method should meet the following conditions:ġ. Polyurethane (PUR) Fluororubber Silicone rubber Suction Cup Types Available Bellows - ideal for concave and convex shapes. Also, according to the international standard, the safety factor of suction cups should be ≥2, so the suction should also divide this safety degree.Īll in all, a 100 mm diameter suction cups should hold a weight ≤27.47 KG.

But as the vacuum degree cannot never reach 100%，generally it will be counted as 70%, then the suction should be: F=78.5*0.7=54.95 KG. So, in theory, the biggest suction force will be 78.5 KG. Lifting Capacity: 70kg ABS Body Lever Operated. Generally means the Atmospheric Pressure.įor example, If a diameter of sucker is 100 mm(10 cm),and the surface area that sucker can covered is 78.5 c㎡. Heavy duty suction lifter, ideal for safely lifting large panes of glass, sheet material and marble. S:The surface area that sucker covered（c㎡） Suction of Suction cups: The force that separate the sucker from the surface of the adsorbing object. Once the suction cup falls off, serious consequences will be caused. As they are big suction cups, the mounted or adsorbed objects are very large or bulky. It is very important to check the airtightness before using the suction cups.Especially the industrial suction cups and heavy duty suction cup hooks.It is also necessary to confirm whether the weight of the adsorbed objects exceeds the adsorption capacity(safety factor must be ≥2). Since it cannot penetrate the surface of the sucker, it forces it to hold the sucker firmly to the surface.If the suction cup surface or edge is damaged and external air enters the suction cup, the suction cup will not work properly and will fall off. As the atmospheric pressure are always trying to keep its equilibrium, this pressure push the external air. Once squeeze the air out, it will turn into vacuum. When we use it, we need to force to press the sucker on the flat and smooth surface.

The bottom of caps has a concave down area.

(Each of our toys come with the option of a permanently Attached Suction Cup or a Double-Sided Suction Cup for $15 while purchasing the toy.The airtightness of material between Rubber and silicone suction cups are both good. We recommend starting with the same size for both sides, however, to best accommodate the ability to craft for unique double-ended toy combination situations you can mix sizes. The larger the size the more weight the suction cup can hold. Don't see your favorite color? Contact us and we'll explore our pigments to find colors perfect for you!Ĭopyright © 2018 Lust Arts LLC.

While testing solutions for Attached Suction Cups for all our flat bases we discovered an effective Double-Sided Suction Cup! In a range of four sizes you can mix and match, these Double-Sided Suction Cups are handmade in Medium density silicone for the best balance of suction and movement.
