Component Specifications

Definition
Positioning pins and bushings are precision-engineered components used in body fixtures and carriers to ensure accurate alignment, repeatable positioning, and secure mounting of workpieces during manufacturing processes. They provide mechanical reference points that eliminate positional errors and maintain dimensional stability throughout production cycles.
Working Principle
These components operate on the principle of mechanical interference and geometric precision. The tapered or cylindrical pin engages with a corresponding bushing to create a precise fit, establishing fixed reference points that constrain movement in specific axes while allowing controlled assembly and disassembly.
Materials
Typically manufactured from hardened alloy steel (AISI 4140, 4340), stainless steel (304, 316), or tool steel with surface treatments like nitriding, chrome plating, or carbide coating for wear resistance. Bushings may incorporate bronze or polymer inserts for reduced friction.
Technical Parameters
  • Hardness 58-62 HRC
  • Concentricity 0.01mm TIR
  • Load Capacity 500-2000N
  • Surface Finish Ra 0.4μm
  • Temperature Range -20°C to 150°C
  • Diameter Tolerance ±0.005mm
Standards
ISO 2768, DIN 6325, ISO 8015

  • Improper installation causing misalignment
  • Material fatigue under cyclic loading
  • Corrosion in harsh environments
FMEA Triads
Trigger: Abrasive wear from repeated insertion/removal cycles
Failure: Increased clearance leading to positional inaccuracies
Mitigation: Implement regular inspection schedules, use hardened materials with wear-resistant coatings, establish replacement intervals based on usage data
Trigger: Contamination by metal chips or debris
Failure: Binding or improper seating causing misalignment
Mitigation: Implement protective covers, regular cleaning protocols, design with self-cleaning features, use sealed bushings where applicable
Trigger: Improper installation force or alignment during assembly
Failure: Component damage or permanent deformation
Mitigation: Use guided installation tools, implement torque-controlled assembly procedures, provide clear installation documentation and training

Frequently Asked Questions

What is the difference between positioning pins and bushings?

Positioning pins are the male components that provide the locating feature, while bushings are the female receptacles that receive the pins. Together they create a precise mating system for accurate alignment.

How do I select the right positioning pin for my application?

Consider load requirements, precision needs, material compatibility, environmental conditions, and required tolerance levels. Hardened steel pins with precise diameters are standard for high-accuracy applications.

What maintenance do positioning pins and bushings require?

Regular cleaning to remove debris, lubrication if specified by manufacturer, inspection for wear or damage, and periodic replacement based on usage cycles and wear patterns.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
