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.

Surface Engineering

BD Boronized vs. DN Diamond Coating

Both coatings available from our in-house treatment line. Choose based on fibre type and speed requirements.

BD — Boronized
Current model · Standard coating
HV 1600–2000
Cost-effective Standard cotton Up to 100K rpm

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.

DN — Diamond
Premium upgrade · Available on request
HV 1000-1200
3–5× longer life Abrasive fibres 110K+ rpm

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.

Compatibility

Which Schlafhorst Machines Use G 530 BD?

Bearing Series 5 rotors fit SE11 and SE12 generation Autocoro machines. Other generations require different spec numbers.

✓ Autocoro 360 — SE11
SE11 generation · Bearing Series 5 · Enhanced rotor speed and automation. Widely operated in South Asia, Turkey, Southeast Asia, and Latin America.
✓ ACO 480 — SE12
SE12 generation · Up to 480 positions · Bearing Series 5 · Same bearing platform as SE11 with advanced individual-spindle drive control.
✗ Autocoro 240 / 288 (SE7/SE8)
Uses Bearing Series 1 — not compatible. Use 1xx spec numbers (e.g. G 133 BD, T 136 BD) for these machines.
✗ Autocoro 312 / 360 (SE9/SE10)
Uses Bearing Series 3 — not compatible. Use 3xx spec numbers (e.g. G 331 BD, G 333 BD) for these machines.
