G 530 BD Rotor Complete
G groove rotor with BD boronized coating for medium to fine count cotton spinning (Ne 16–40) on Autocoro 360 / ACO 480 series. 100% dynamic-balanced. Custom profiles available from our in-house production line.
G 530 BD — Complete Specifications
All measurements in millimetres. Each rotor undergoes 100% dynamic balance testing before shipment.
Why G Groove for Medium to Fine Count Cotton
The G groove is the industry-standard profile for cotton spinning in the Ne 16–40 range.
G Groove — Applicable Yarn Count Range
Optimized for medium to fine counts. For coarse counts (Ne 3–16), consider the GT groove.
G Groove — Precision Fibre Control for Cotton
The G groove geometry creates a controlled deposition zone inside the rotor, ensuring cotton fibres are uniformly distributed and twisted. This translates to higher yarn evenness (lower CV%) and fewer thin/thick places — critical for medium to fine count weaving and knitting applications.
Optimized for Ne 16–40
The G groove’s geometry is calibrated for medium to fine cotton, delivering stable fibre separation and consistent yarn formation across the full Ne 16–40 count 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 G 530 BD?
