T 536 BD Rotor Complete
T narrow groove rotor with BD boronized coating for fine and medium-fine yarns (Ne 16–40) on Autocoro 360 / ACO 480 series. 100% dynamic-balanced. Custom profiles available from our in-house production line.
T 536 BD — Complete Specifications
All measurements in millimetres. Each rotor undergoes 100% dynamic balance testing before shipment.
Why T Groove for Fine Yarn
The T groove’s narrow profile is engineered for fine and medium-fine yarns in the Ne 16–40 range.
T Groove — Applicable Yarn Count Range
Optimized for fine counts. For coarse counts (Ne 3–16), consider the GT groove.
T Groove — Precision Fibre Control for Fine Yarn
The narrow T groove geometry creates a compact deposition zone inside the rotor, ensuring fibres are uniformly distributed and twisted even at fine counts. This translates to higher yarn evenness (lower CV%) and fewer thin/thick places — critical for fine count knitting and weaving applications.
Optimized for Ne 16–40
The T groove’s narrow geometry is calibrated for fine and medium-fine yarns, delivering stable fibre separation and consistent yarn formation across the full Ne 16–40 range.
Consistent Yarn Evenness
Stable fibre deposition zone produces CV% values consistently below Uster 25% benchmarks, critical for downstream knitting and weaving quality.
Reduced End Breakage
Optimized twist propagation path reduces spinning tension peaks, lowering end-break rates and improving machine efficiency on SE11/SE12 platforms.
Self-Cleaning Geometry
The groove’s parabolic cross-section prevents micro-dust accumulation — a root cause of periodic faults and moiré patterns in long-run production.
BD Boronized vs. DN Diamond Coating
Both coatings available from our in-house treatment line. Choose based on fibre type and speed requirements.
Thermochemical diffusion process forms a hard boride layer (FeB/Fe₂B) on the substrate. Excellent wear resistance at a competitive price. Ideal for standard cotton production where cost-per-kg is the priority.
CVD diamond-like carbon coating delivering extreme surface hardness. Recommended for abrasive fibres (recycled cotton, coloured cotton, viscose blends), high-speed production, and mills targeting maximum uptime and longest service intervals.
Which Schlafhorst Machines Use T 536 BD?
