It is designed for coarse, corrugated, embossed and uneven surfaces such as diamond plate, rough-sawn wood, raw lumber, brick, stone and textured tiles.

It may be used on some porous materials, but the vacuum source must provide enough flow to compensate for air leakage through the workpiece. Application testing is recommended before determining the safe working load.

Using the full nominal 100mm circular area, the theoretical lifting force at 24"Hg is approximately 62.8kg / 143.1lb. This is not the safe working load and does not account for the actual internal opening, leakage or application safety factor.

The 100mm diameter equals approximately 3.937 inches, producing a nominal area of 12.17 square inches. At 80% vacuum, the effective pressure is approximately 11.76 PSI. Therefore, 12.17 × 11.76 provides a theoretical force of approximately 143.1lb.

A 100mm diameter equals 10cm, giving a nominal circular area of 78.54cm². At approximately 80% vacuum, the theoretical lifting force is 78.54 × 0.8, or approximately 62.8kg.

Actual force may be reduced by the internal vacuum opening, workpiece porosity, uneven seal compression, surface leakage, acceleration, side loading, contamination, vacuum losses and variations in operating altitude.

Yes. The calculated lifting force is theoretical. An appropriate engineering safety factor must be applied based on the load orientation, movement, acceleration, workpiece condition, vacuum level and risk of injury or product damage.

This product is an EPDM foam replacement seal. The compatible vacuum cup body, mounting plate, fitting or complete assembly may be supplied separately unless specifically included in the product listing.
