SMC ZPT16UUJ10-B5-A10 | ZP Series Basic Flat Vacuum Pad 16mm Vertical Inlet With Buffer Urethane Rubber 10mm Stroke Mark-Free Soft Spring

The SMC ZPT16UUJ10-B5-A10 is a basic flat type vacuum pad from the ZP series, featuring a 16mm pad diameter with urethane rubber construction, vertical vacuum inlet, and 10mm buffer stroke with J-type soft spring. The "UU" material specification indicates urethane rubber for both the contact pad and sealing elements, establishing this as the premier mark-free variant in the 16mm flat pad range for applications where workpiece surface cosmetics are a critical quality parameter.

What surfaces benefit most from urethane pad material? Urethane rubber produces virtually zero visible contact marks on polished metals, glass, coated plastics, painted surfaces, display panels, and optical components. This makes the ZPT16UUJ10 the standard selection for cosmetic inspection stations, display panel transfer, automotive trim handling, consumer electronics assembly, and medical device packaging where any visible pad impression would constitute a quality rejection.

The J-type soft buffer spring further protects surface-sensitive workpieces by reducing the initial contact force during pad approach, minimizing any risk of impression or deformation on soft or semi-rigid materials. The 10mm buffer stroke provides moderate Z-axis compliance while keeping the overall assembly compact. Urethane operates within 0°C to +60°C, which covers the majority of clean assembly environments where mark-free handling is specified.

The "B5" fitting specification and "A10" buffer body size this pad for standard tooling integration. This vacuum pad is RoHS compliant and compatible with SMC's complete vacuum product range. Part of the ZPT series offering 2 to 125mm diameters across six materials including NBR, silicone, urethane, FKM, and conductive variants.
