Special rubber part

Special rubber parts for mechanical and plant engineering, to your requirement profile

JRT Elastomertec makes custom special parts in soft rubber and rubber-to-metal bonds, adapted to the application. We recommend the material from a wide range to suit your requirement profile.

What special parts do in machines and plants

Special parts optimise production processes, absorb strong forces in high-vibration processes and protect sensitive machine components. They can be designed to resist weathering and aggressive media such as mineral oils and greases.

Types of special parts

01

Bellows

We make bellows in different types, shapes and sizes. Bellows protect moving parts such as spindles, shafts or joints from dirt while compensating for changes in length. For special machinery we also make convoluted hoses.

02

Expansion joints

Expansion joints act as buffers, for example on vibrating machines. We supply them to special machinery and plant engineering, and coupling expansion joints are also part of the range.

03

Rubber bags for pressing processes

Rubber bags with a capacity of up to 3 m³ are used in pressing processes for carbon, ceramics and hard metals.

AUSBAUWhich pressing process exactly are the rubber bags used for?
04

Sealing bladders, rubber buffers and roller covering

The range also includes sealing bladders, rubber buffers, rubber coating for metal hoses and roller covering.

AUSBAUDo you coat rollers, and up to what diameter and length?

Rubber sleeves

Rubber sleeves are part of our range of technical rubber goods. In a pinch valve the sleeve is the flexible hose body that is squeezed to close. We supply sleeves to material handling, among others. Flange sleeves are made as soft rubber moulded parts.

AUSBAUIn which nominal sizes, materials and installation cases do you make sleeves?
Dark cylindrical rubber parts

FAQ: special parts

Which technical criteria matter for special parts in mechanical engineering?

What matters are the temperature and pressure conditions and the media the part must withstand, plus where it works in the machine.

Are there food-grade special parts?

Yes, when needed we make food-grade special parts for use in the food industry.

Do you make sleeves for pinch valves?

Yes, sleeves for pinch valves are part of our range.

Do you supply special parts as assemblies?

Yes, we can also supply them as assemblies.

Can you test special parts before delivery?

Yes. On request our in-house laboratory tests pressure and vacuum or the conductivity of the part, for example.

AUSBAUWhich quantities and lead times are usual for special parts?
