- Hardness range: 10-100 Shore A, 45-85 Shore D, 0-200 P&J
- Maximum weight of the elastomerically coated roller: 10 t
- Manufacturing of rollers (manufacturing of the core according to drawings and sketches, followed by coating with specified properties)

- Roller length up to 7 m, diameter up to 900 mm
Restoring the coating (rubberisation) of rollers using rubber compounds and polyurethanes
- The high wear resistance characteristics of one- and two-component polyurethane coatings make them widely used in various industries.
- The polyurethanes are supplied from the UK.
- Rubber compounds used: NBR, NBR/PVC, EPDM, HY, NE, SBR, XNBR, SILICONE, EPDM/Silicone. A wide range of rubber grades allows you to choose the coating with the best performance characteristics for any application (see the table of properties).
- The tyres are supplied from Germany, England and Italy.
- Special coatings for printing and industrial equipment - containing hydrophilic elements, resistant to abrasion, aggressive chemicals
Rollers manufacturing (metal rods)
- With the necessary metalworking equipment (turning, milling, grinding machines - including CNC, balancing, etc.), DESSA-NV performs the full range of works: diagnostics, repair, and manufacture of roller fittings in the shortest possible time at a high technical level.
- Металева поверхня валів може бути подальше покрита гумою / поліуретаном або виконується фінішна обробка згідно з технічним завданням.
- Defects and repairs
- Production of separate rubber sleeves
- Designing based on customer specifications
- Manufactured entirely using high-quality components (bearings, etc.)
Repair of rollers (metal rods)
- Repair of bearing seats
- Replacing the trunnions
- Eliminating shaft barrel defects
- Balancing (READ MORE)
- Rolls, rollers and other parts designed to operate in harsh environments with abrasive wear, high loads, temperature fluctuations in the presence of aggressive media
Grinding
- High surface roughness class after grinding (Ra from 0.30 depending on the roller coating material)
- Any surface profile - cylinder, cone, saddle, parabolic bombardment
- With the use of CNC
- High geometry accuracy (from 0.01 mm)
- The grinding of words is performed with the use of additional equipment
Slicing roller surfaces
Cutting sticks - PVC, HDPE, NYLON, PU
- For the attention of printers, imported and own production of marzans for cutting equipment made of materials - PVC, HDPE, Nylon, PU
Inking blades
made from polyurethane
- One of the applications of high-strength polyurethanes is the production of squeegees (flushing knives) for the printing apparatus of printing machines
