Technical Specifications & Design Philosophy
Oval Bushings
- Non-Circular Geometry: Engineered with precisely calculated elliptical profiles to accommodate irregularly shaped workpieces or measurement paths
- Eccentricity Tolerance: Maintains ±0.0005" concentricity for off-axis measurement scenarios
- Material Science: Manufactured from case-hardened alloy steel (HRC 60-62) or corrosion-resistant 440C stainless steel
- Surface Integrity: Super-finished to Ra ≤ 0.2 μm to prevent particulate contamination in cleanroom environments
Shouldered Bushings
- Axial Positioning System: Integrated shoulder design provides positive vertical registration within ±0.0003"
- Modular Stacking Capability: Precision-ground shoulders enable multi-tiered fixturing configurations
- Thermal Compensation: Coefficient of thermal expansion matched to common fixture plate materials (e.g., granite, aluminum)
- Anti-Rotation Features: Optional keyways or diamond-knurled shoulders prevent rotational slippage
- Measurement Uncertainty Reduction: Minimize systemic error contributions to ≤0.1% of measured values
- Wear Resistance: Tungsten carbide liner options available for high-cycle applications (>500,000 cycles)
- Interchangeability: Manufactured to ISO 286-2 standards for seamless integration with existing tooling
- Vibration Damping: Proprietary polymer-impregnated variants reduce harmonic distortion in dynamic measurement systems
