Grip Neck Stem
Product Features
Fluid 360° Swivel Response
Integrated with an industrial dual-bearing swivel race that reduces rolling friction, allowing seamless changes in direction even under maximum load limits.
Eco-Friendly Recycled Nylon Body
The outer wheel housing is injection-molded using high-purity recycled nylon polymers. This delivers outstanding impact resistance while meeting green corporate procurement policies.
Trivalent Chromium (Cr3+) Protection
All heavy-duty steel stem components undergo an advanced Cr3+ zinc electroplating treatment. This provides excellent salt-spray rust protection while ensuring complete non-toxicity.
Customization Services (OEM / ODM)
Bespoke Stem Profiling: If your furniture frames require a non-standard neck gap or custom head profile, our automated tooling center can modify the stem geometry to match your proprietary prints.
Floor-Protecting Soft Treads: Polyurethane (PU) overmolding is available to ensure scratch-free movement on premium marble, hardwood, or continuous resin commercial floors.
Quality & Compliance
ANSI/BIFMA X5.1-2017 Certified: Fully independently audited and verified to comfortably pass international commercial office seating drop-impact and structural loading benchmarks.
Environmental Safety Verification: Materials are fully compliant with RoHS and REACH directives. Our structural pins pass a rigorous 50,000+ continuous rotation fatigue cycle test to eliminate operational failure.
