K1,5 CONTI® SYNCHROFLEX polyurethane timing belt

Version:

  • Single-sided
  • Notched profile with metric pitch
  • The technical data refer to the high performance casting polyurethane and steel tension members.
  • Belt lengths < 100mm (application of casting polyurethane DADU 9311, colour yellow
  • Preferred belt widths: 4, 6, 10 mm

On request:

  • Double-sided; with flights on the back of the belt; with reinforced back of the belt; polyurethane special materials; further tension member versions (steel, textile tension member); antistatic, coloured, mechanical reworked
  • In-between widths, larger widths and other dimensions

Please consider our warranty.
