Successful operation of an industrial shaft on the 70% depends on the selection of the right rubber coating. Its chemical composition, hardness and wear resistance determine how long the shaft will perform its function without deformation, cracks or delamination. At Dessa-NV LLC, we work only with proven European suppliers of elastomers - Hexpol, Kraiburg - and select compounds for specific conditions.
🧪 What to consider when choosing rubber for the shaft
Key factors:
- Operating environment (water, oil, glue, varnish, chemicals)
- Temperature - constant or cyclic, up to +250 °C
- Physical stress - pressure, abrasive, surface contact
- Process type - printing, applying, pressing, material handling
- Required roughness and profile
🔍 The most popular types of shaft rubbers
Material. | Characteristics | Where it is used |
NBR (nitrile) | Resistant to oils, fuels, adhesives | Printing, varnishing, glue application |
EPDM | Resists ozone, steam, UV, acids | Food and pharmaceutical industry |
SBR | Versatile, inexpensive, moderate wear resistance | Paper and textile industry |
PU (polyurethane) | Ultra-high wear resistance, low friction | Metallurgy, transport shafts |
Silicone | Temperature-resistant, inert | Food and medical applications |
HNBR, FKM, fluoroelastomers | High chemical and temperature resistance | Aerospace, chemical industry |
⚙️ What else is important?
- Hardness: 30 to 95 Shore A - selected according to the load
- Colour: not only aesthetics, but also a sign of the mixture (EPDM - grey, NBR - black, PU - yellow or green)
- Adhesion to the rod: ensured by chemical surface preparation
- Curing method: autoclave or continuous line - depending on the polymer
