Heavy Duty Steel and Glass Handling Vacuum Suction Cups

Heavy-Duty Vacuum Gripping for Sheet Steel, Glass and Large Products

SFF Series heavy-duty flat vacuum cups are designed for handling products such as pressed sheet steel and glass where strong grip and tolerance for slight surface angles or radii are important. The cup can adapt to mildly concave or convex surfaces and includes an aluminum threaded fitting for connection to machinery and the vacuum source.

The source range uses 60-durometer NBR as the standard rubber material, with other durometer grades available on request. The design is particularly suited to demanding sheet and panel handling.
