It is designed for smaller rough, textured and uneven workpieces such as stone tiles, wood offcuts, brick samples, embossed components and small patterned surfaces.

Using the full nominal 60mm circular area, the calculated theoretical lifting force is approximately 22.6kg at 80% vacuum or 51.5lb at 24"Hg. These figures are not safe working load ratings.

A 60mm diameter equals 6cm and has a nominal circular area of approximately 28.27cm². At 80% vacuum, the theoretical force is 28.27 × 0.8, which equals approximately 22.6kg.

The 60mm diameter equals approximately 2.362 inches, producing a nominal area of 4.38 square inches. At 24"Hg, the effective pressure is approximately 11.76 PSI. Therefore, 4.38 × 11.76 provides a theoretical force of approximately 51.5lb.

The seal is primarily intended to conform to rough and uneven surfaces. Some porous workpieces may be handled, but this depends on the vacuum source providing enough airflow to compensate for leakage through the material. Application testing is required.

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

Yes. The stated lifting figures are theoretical. An appropriate engineering safety factor must be applied based on load orientation, acceleration, surface condition, leakage, vacuum level and the risk of injury or product damage.

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