High-friction suction cups

Duraflex friction cups are designed to provide strong grip on oily and wet surfaces and they are particularly suitable for the automotive and whitegoods manufacturing industries.

Duraflex friction cups feature a rough cleat surface and sharp cleat edges and channels. This design creates greater friction and a stronger hold compared to traditional traction suction cups. Normal cup abrasion resulting from handling oily sheets does not degrade the shear force performance of PIAB’s friction cups over time. The added durability of the cups extends use life for long-term reliability.

These friction cups maintain their hold on heavy and slippery sheets during acceleration and deceleration, especially during emergency stoppages. Made of Duraflex polyurethane, PIAB’s friction cups will not break or crack after exposure to ultraviolet light, heat or ozone.

To prevent damage to the surface of thin metal sheets, Duraflex friction cups feature a dual-hardness design and soft cup body. Lower vacuum force is needed to seal the cups to part surfaces for gentler handling. The soft lip of the friction cups also moulds easily to curved surfaces for less vacuum leakage and stronger grip. The cups also maintain their elastic memory and original shape for an expanded life cycle.

Manufacturers can choose from two models. The BFF model is suitable for handling concave and convex surfaces, while the FCF model offers increased stability for handling larger metal sheets. For products with narrow surfaces, the friction cups are also available in an oval shape. The cups operate between temperatures of 10 and 50 °C.
