Info on our rubber balls

Production:

Rubber balls are molded using compression presses with the innovative integral vacuum technology.

After molding, our rubber balls are finished with an accurate and high speed grinding process.

The finishing process eliminates the burrs and a smooth and uniform surface is obtained.

The grinding process provides accurate dimensions that are necessary to produce an effective seal.




Types of rubber used:

POLYURETHANE RUBBER (AU - EU)

NITRILE RUBBER (NBR)

ETHYLENE-PROPYLENE-DIENE RUBBER (EPDM)

SILICONE RUBBER (VMQ)

Our polyurethane rubber balls offer high tensile and tear strength for applications on gears, sprockets and applications that require high resistance to pure aliphatic hydrocarbons.

We recommend nitrile rubber balls for resistance to oil abrasion and temperatures up to 125 ° C (in oil).

For applications with exposure to atmospheric agents, we recommend our EPDM rubber balls.

The silicon rubber balls, on the other hand, can guarantee high elasticity and heat resistance, in fact they have a very wide range of use as regards the temperatures they can be subjected (from -60 ° to + 180 °). They resist very well to exposure to ozone and atmospheric agents. They cannot be rectified.




Typical uses of rectified rubber balls:

Tedeschi Gomma solid rubber balls are used on Wellpoint systems (construction pumps), as valves for sprinkler devices, as shock absorbers for truck reverse buffers, as sealing valves for submerged pumps.

The Tedeschi Gomma's rubber balls with nylon core are used as check valves for priming slurry pump systems, such as floats inside aqueduct piping vents, as floats for air intake closure for tank filling, as floats for sanitary ware milking systems, such as floats for overflow valves.

The balls with steel core are used as valves for enological piston pumps.

  • Solid spheres applied on truck reverse bumpers            
  • Floating sphere for sanitary vessel of milking plants 
  • Full ball applied on valve for watering device

 

At the request of the customer all our items can be produced with different compounds from those mentioned.
