Description
Suction Cup Rubber Feet for Non-Slip Support
Barbieri Rubber suction cup feet are anti-vibration supports with a concave suction-cup base, designed for floor adhesion and non-slip behavior. Under the weight of the equipment, the lower cavity creates a suction effect that keeps the foot bonded to the supporting surface. They are catalog rubber components, available in multiple sizes, hardness levels, with or without threaded insert.

What a suction cup foot is for
Suction cup feet are ideal for small equipment, benchtop tools, instruments, portable pump units, cases, technical cases, containers, furniture and any object that must remain stable on a smooth surface without mechanical fixing. The suction base grips smooth floors and prevents sliding, avoiding the need for fixing holes or adhesives. They perform best on smooth, clean, dust-free surfaces.
Available compounds and typical hardness
The most common rubber for suction cup feet is SBR, with typical hardness 40-60 Shore A. Lower hardness increases suction effect but reduces durability; medium hardness offers a good balance between grip and wear resistance. For oil exposure NBR is used, for outdoor EPDM, for high temperatures VMQ silicone.
| Compound | Temperature range | Feature | Typical applications |
| SBR | -20 / +90 °C | Balanced mechanical performance | General-purpose feet |
| NBR (Nitrile) | -40 / +130 °C | Mineral oil resistance | Workshops, hydraulics |
| EPDM | -40 / +100 °C | UV, ozone and outdoor resistance | Outdoor, photovoltaic |
| VMQ (Silicone) | -60 / +200 °C | High temperature | Ovens, hot environments, food |
| FKM (Viton®) | -10 / +180 °C | Aggressive oils and solvents | Chemical, automotive |
Standard version and custom designs
The standard range of suction cup feet covers the most recurrent sizes, with active tooling at Barbieri Rubber and no tooling cost. For special sizes, off-spec hardness, dedicated threaded inserts or specific compounds we produce custom versions: at least a preliminary drawing from the customer is required. The dedicated mold is manufactured in cooperation with our trusted toolmaking partners.
Suction cup feet applications
Suction cup feet are used on benchtop equipment, measuring instruments, cases, technical cases, industrial containers, technical furniture, cutting boards, scale and balance bases, small appliances, portable pump units and any object that must remain stable on a smooth surface without fixing. They are appreciated for their ease of application: often press-fit or fastened with a threaded insert.
Frequently asked questions
On which surface do suction cup feet work?
They work best on smooth, clean, dust- and oil-free surfaces: glass, polished metal, smooth plastic, smooth worktops. On rough, porous or dirty surfaces the suction effect is reduced.
Are suction cup feet available from stock?
Yes, the most requested sizes are catalog rubber components, with no tooling cost for the customer. For special sizes we produce custom versions with a dedicated mold.
Are they resistant to oils or chemicals?
With standard NR/SBR compounds, chemical resistance is limited. For oil exposure NBR is used, for outdoor EPDM, for high temperatures VMQ silicone, for aggressive agents FKM (Viton®). Special compounds are available on request.
