Floating Nut Assembly
Products Description
Our floating nut assembly employs a cage-like enclosure structure, placing the nut within a metal or engineering plastic cage. This allows the nut to float within a limited range in the X-Y directions while restricting movement in the Z direction. This unique design completely solves the alignment problems caused by hole misalignment during the assembly of traditional fixed nuts, significantly improving installation efficiency and structural reliability.
Key Product Features:
Multi-directional Floating Capability: The nut can float radially within a certain range within the cage, automatically compensating for assembly deviations.
Quick Self-alignment: During installation, the screw easily guides the nut to alignment, reducing manual adjustment time.
Anti-drop Design: The cage structure reliably locks the nut, preventing it from falling or being lost during assembly.
High Repeatability: Optimized to withstand multiple disassembly and assembly cycles while maintaining stable floating performance and clamping force.
Core Industry Application Scenarios
Cloud Data Center and Communication Cabinets (IT & Telecom Racks)
For rapid modular assembly of standard 19-inch server racks, network switches, and patch panels.
New Energy and Smart Grid Control Cabinets
Adapting to complex sheet metal assembly tolerances within high and low voltage switchgear and ring main units.
Railway & Automotive Electronics
Resisting continuous mechanical vibration during locomotive operation, ensuring the secure fastening of the power control system.
Material Advantages: A Heterogeneous Synergistic Engine of Rigidity and Flexibility
| High Shear Rigidity Thread Base | The internal Cage Nut Assembly bears the heavy responsibility of thread engagement and axial tensile force, requiring absolute rigidity. We select high-carbon steel or SUS304/316 stainless steel, which undergoes hardening and passivation treatment, resulting in fine grains and full thread profiles. This ensures no stripping or disengagement under the highest allowable torque, providing durable load-bearing capacity. |
| High Elastic Limit Spring Steel Cage | The external cage is the source of elasticity and must withstand repeated tests of push-in, rebound, and crushing. We select high-quality spring steel (such as 65Mn) or 301 semi-hard stainless steel. Through precise annealing and quenching tempering processes, the material reaches the "golden range" of elasticity-possessing sufficient yield strength to resist permanent deformation and excellent elastic recovery to lock the sheet metal. |
| Surface corrosion protection and friction control | For outdoor and high-humidity environments, the cage is made of electroplated zinc-nickel alloy or Dacromet coating to provide ultra-long salt spray protection; the internal threads are coated with anti-seize grease or Teflon coating to keep the coefficient of friction in an extremely low range, ensuring that the tightening torque is efficiently converted into clamping force rather than consumed as thread friction heat. |
Detailed Showcase | The "Hidden" Strength that Determines Quality
Extended Spring Life Design
An added radius (R-angle) at the root bend of the spring clip mitigates stress concentration points. Combined with precision heat treatment, this prevents fatigue fracture during high-frequency assembly and disassembly.
Coating Uniformity and Environmental Adaptability
The zinc coating thickness of the carbon steel floating nut is uniform. In areas difficult to coat, such as the inner wall of the cage, spring clip gaps, and the area around the nut, optimized solution circulation and electrical parameter arrangement ensure complete coverage, preventing early corrosion due to uncoated areas.
Thread Protection and Anti-locking Treatment
Before assembly, a small amount of anti-seize coating or process lubricant can be added to the thread surface of the Cage Nut Combo, according to customer needs, to prevent thread seizing caused by the "cold welding" characteristics of stainless steel, improving the actual assembly experience.
Thread Protection and Anti-locking Treatment
Anti-mixing and traceability marking: When supplying in bulk, U-Nut Floating Assemblies of the same specification but different materials can be equipped with stamped letter markings on the cage surface (e.g., SS for stainless steel, CS for carbon steel) to avoid incorrect material loading on site.
