U 136 BD — Complete Specifications
All measurements in millimetres. Each rotor undergoes 100% dynamic balance testing before shipment.
Why U Groove for Your Yarn Count Target
The U Groove is engineered for cotton and general-purpose blends across medium to coarse counts.
U Groove — Applicable Yarn Count Range
For fine counts (Ne 30+), consider the G or T groove.
U Groove coverage (Ne 10–30)
U Groove — Precision Fibre Control for Target Yarn
The U Groove geometry creates a controlled deposition zone inside the rotor, ensuring cotton and general-purpose blends across medium to coarse counts are uniformly distributed and twisted.
Optimized for Ne 10–30
The U Groove’s geometry is calibrated for cotton and general-purpose blends across medium to coarse counts.
Consistent Yarn Evenness
Stable fibre deposition zone produces CV% values consistently below Uster 25% benchmarks.
Reduced End Breakage
Optimized twist propagation path reduces spinning tension peaks.
Self-Cleaning Geometry
The groove’s parabolic cross-section prevents micro-dust accumulation.
BD Boronized vs. DN Diamond Coating
Both coatings available from our in-house treatment line.
Thermochemical diffusion process forms a hard boride layer on the substrate. Excellent wear resistance at a competitive price.
CVD diamond-like carbon coating delivering extreme surface hardness for abrasive fibres and high-speed production.
