Industry-Verified Manufacturing Data (2026)

Joint Housing

Based on aggregated insights from multiple verified factory profiles within the CNFX directory, the standard Joint Housing used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.

Technical Definition & Core Assembly

A canonical Joint Housing is characterized by the integration of Bearing Seat and Seal Groove. In industrial production environments, manufacturers listed on CNFX commonly emphasize Aluminum Alloy construction to support stable, high-cycle operation across diverse manufacturing scenarios.

The structural enclosure that houses and protects the internal components of an articulated arm joint.

Product Specifications

Technical details and manufacturing context for Joint Housing

Definition
In articulated arm sections, the joint housing is the protective outer casing that contains and shields the joint's internal mechanisms such as bearings, seals, and lubrication systems. It provides structural integrity, maintains alignment of moving parts, and protects against environmental contaminants while allowing controlled articulation.
Working Principle
The joint housing functions as a rigid enclosure that maintains the geometric relationship between connected arm segments. It contains the pivot point or rotational mechanism, distributes mechanical loads, and provides mounting surfaces for adjacent components. During articulation, the housing remains stationary relative to the joint while internal components rotate or pivot within it.
Common Materials
Aluminum Alloy, Cast Iron, Stainless Steel
Technical Parameters
  • Housing outer diameter and wall thickness (mm) Standard Spec
Components / BOM
  • Bearing Seat
    Precision surface for bearing installation and alignment
    Material: Hardened Steel
  • Seal Groove
    Channel for installing sealing elements to prevent contamination
    Material: Same as housing material
  • Mounting Flange
    Interface for connecting to adjacent arm sections
    Material: Same as housing material
Engineering Reasoning
0-150 MPa internal pressure, -40°C to 120°C ambient temperature
Yield strength exceeded at 180 MPa internal pressure or 140°C material glass transition temperature
Design Rationale: Von Mises stress exceeding 7075-T6 aluminum yield strength (503 MPa) or polymer creep deformation above Tg
Risk Mitigation (FMEA)
Trigger Misalignment-induced bending moment exceeding 450 N·m
Mode: Housing wall fatigue crack propagation from stress concentration at bolt holes
Strategy: Finite element analysis-optimized rib geometry with 2.5x safety factor on bending loads
Trigger Contaminant ingress (ISO 4406 Class 18/16/13) causing abrasive wear
Mode: Radial clearance increase beyond 0.05 mm tolerance, inducing joint backlash
Strategy: Triple-lip PTFE seal with 0.3 MPa sealing pressure and IP67 rating
