Vacuum Cups and Suction Cups from 2.8mm to 15.7mm
Small Suction Cups for End-of-Arm-Tooling (EOAT) and General Industrial Use
In addition to our general purpose vacuum grippers, vacuum cups and suction cups, ANVER offers an extensive line of small vacuum cups and suction cups for end-of-arm-tooling. These are well suited to the automation and handling processes of high technology industries, including plastic injection molding sprue picker robots etc. Type, size, shape and material are strictly determined by the end process use. Many of the cups listed below will interchange with other manufacturers’ products. The -ESD cups on this page are molded from Electro-Static Dissipative NOMASTAT® material. We have more information on materials here. |

The cup capacities shown above ( * ) are theoretical capacities based on 24″Hg at sea level with a safety factor of two (2) and a ± 5% margin of error. This is the US ANSI ASME Standard B30.20 for vacuum lifter specifications and is commonly used in North America as a design capacity for vacuum components. When used in vertical applications, take these values and divide again by 2 to obtain a 4 to 1 safety factor per the ANSI specifications. These are realistic working capacities when designing equipment.
-
Other manufacturers use a pull-off figure at 27″Hg to show a high capacity value for their cups. This is accurate, but requires users to do all the math themselves to build in safety factors. The values are basically the same, but it is necessary to calculate the working capacities with a safety factor via the following formula at sea level:
Pull-off value (at 27″Hg) = ANVER’s Listed Capacity x 2 x 1.125 (at 24″Hg)
-
For example: ANVER vacuum cup number F52 has a rated capacity of 15.10 lb at 24″Hg. The pull-off capacity at 27″Hg for this cup would be 15.10 x 2 x 1.25 = 33.79 lbs. From this point, it is necessary to calculate the safety factor based on the vacuum level being used, and the altitude.
-
To ensure safety, 80% of actual overall diameter is used when determining Load Capacity.
