How to Choose a Rotor Complete for Saurer BD Machines
The correct rotor configuration depends on the operating speed, yarn count, fibre characteristics, rotor diameter and coating. Machine model is only one part of the selection process.
Match the Rotor to Speed
Start with the actual operating speed of the spinning machine.
- T100 configurations — up to 110,000 rpm
- 72-8 configurations — up to 80,000 rpm
- Large-diameter rotors — lower recommended speeds
Match Rotor Diameter to Application
Rotor diameter and configuration should be selected according to yarn count and fibre characteristics.
- T32 / T33 / T34 / R36 — standard applications
- T40 / T43 / V43 — medium and coarse applications
- L54 / Z54 / Z66 — large-diameter applications
Select the Coating
JSM offers different coating choices according to fibre characteristics, operating conditions and required service performance.
- D — Diamond coating
- DN — Diamond + Nitride coating
- BD — Boronized coating
