This heavy-duty traction-style NBR cup is intended for handling press-formed sheet metal, oily steel blanks and industrial panels where a durable sealing lip and reliable contact are required.

STC uses a traction / bellows-style profile to accommodate some height and surface variation; SFF is a flatter style often chosen for fast lateral transfers. Select by the actual panel shape, acceleration and available landing area.

The model identifies nitrile rubber (NBR) at 60 Shore A. Check performance against drawing oils, temperature, contact pressure and any surface-marking restrictions.

The listed connection is 3/8 NPSF female. Confirm the port, fitting seal and mounting-envelope dimensions before installation.

The traction / single-bellows profile can help with modest contour and height differences. Test at the intended vacuum level on the worst-case formed panel, including oil and surface contamination.

The published lifting values are theoretical axial estimates at a stated vacuum level, not a rated safe working load. Account for acceleration, friction, leakage, surface condition and orientation; confirm the cup layout through application trials.

Monitor lip wear, cycle count, forming-oil build-up, vacuum response, hose routing and release timing; ensure replacement cups match the model and mounting interface.
