Unlike generic jacks, this product is built for long-term, high-intensity use, focusing on reducing maintenance costs and improving knitting consistency. Sold in 50 PCS packs, it is compatible with most mainstream flat knitting machine brands (not limited to STOLL) and is widely used in apparel, knitwear, and small-batch customization workshops.
Model: J88.73B
Packaging Quantity: 50 PCS per carton
Gauge Compatibility: 7G-14G (suitable for medium-to-fine gauge knitting)
Material:
Core: High-carbon steel (HRC 60-62) for impact resistance
Coating: Titanium nitride (TiN) plating for reduced friction (coefficient of friction ≤0.15)
Dimensional Tolerance: ±0.008mm (CNC grinding process)
Operating Temperature Range: -10°C to 90°C (adapts to different workshop climates)
Service Life: ≥8,000 hours of continuous operation (under standard conditions)
Compatibility: Works with flat knitting machines from brands like STOLL, Shima Seiki, and China’s local manufacturers (e.g., Hengyuan)
Broad Compatibility: Designed to fit multiple flat knitting machine brands, eliminating the need to stock brand-specific jacks.
Low Wear Rate: TiN plating reduces friction between the jack and needle, extending service life by 40% compared to unplated jacks.
Consistent Precision: Ultra-tight dimensional tolerance ensures every jack in the 50 PCS pack performs identically, avoiding fabric defects caused by uneven jack movement.
Easy Installation: Lightweight design (15g per unit) and standard mounting holes enable quick replacement (no special tools required).
For independent designers or small workshops producing custom sweaters, cardigans, or children’s knitwear, the J88.73B jack’s compatibility with multiple machines allows flexible use across different equipment. Its 50 PCS pack size is cost-effective for low-volume needs, avoiding overstock.
Factories handling seasonal orders (e.g., winter sweaters, summer knit tops) benefit from the jack’s long service life. Reduced replacement frequency means less downtime during peak production periods, helping meet tight delivery schedules.
Vocational schools or training centers teaching knitting technology rely on the J88.73B’s durability and consistency. The jacks withstand frequent use by students and provide reliable performance for hands-on training sessions.
Technical Consultation: Free pre-purchase advice to confirm compatibility with your specific flat knitting machine model.
Sample Testing: 1-3 free samples available to test performance before bulk ordering.
Maintenance Guide: Detailed PDF manual (in English/Chinese) with tips on cleaning, lubrication, and troubleshooting.
Warranty: 6-month warranty; if jacks fail due to manufacturing defects, we offer free replacements.
Bulk Discounts: 5-15% discounts for orders ≥10 packs (500 PCS); custom packaging (e.g., labeled with your brand) available for large orders.
