Product Specifications

Technical details and manufacturing context for Carriage/Travelling Block

Definition
The carriage/travelling block is a critical component of leader systems used in various industrial machinery. It functions as a movable platform that travels along linear guides or rails, providing precise positioning and support for attached tools, cutting heads, or workpieces. In leader systems, it enables controlled linear motion for operations such as drilling, milling, cutting, or assembly processes.
Working Principle
The carriage/travelling block operates by converting rotational motion from drive mechanisms (such as ball screws, rack-and-pinion systems, or linear motors) into precise linear movement along guide rails. It maintains alignment through bearings or sliding surfaces while supporting loads and transmitting forces to perform specific industrial functions.
Common Materials
Cast Iron, Steel Alloy, Aluminum Alloy
Technical Parameters
  • Travel length along the guide system (mm) Standard Spec
Components / BOM
  • Guide Rail Interface
    Provides smooth linear motion along guide rails
    Material: Hardened Steel
  • Mounting Plate
    Surface for attaching tools or workpieces
    Material: Steel Alloy
  • Drive Mechanism Interface
    Connection point for ball screw, rack, or linear motor
    Material: Steel
Engineering Reasoning
0.5-3.0 m/s linear velocity, 50-500 kg load capacity, -20°C to 80°C ambient temperature
Linear velocity exceeding 3.5 m/s causes bearing seizure, load exceeding 550 kg induces permanent rail deformation, temperature beyond 85°C degrades lubricant viscosity below 68 cSt
Design Rationale: Hydrodynamic lubrication breakdown at Stribeck curve transition (λ < 1), Hertzian contact stress exceeding rail material yield strength (σ_y > 345 MPa), Arrhenius-accelerated lubricant oxidation at elevated temperatures
Risk Mitigation (FMEA)
Trigger Particulate contamination exceeding ISO 4406 18/16/13 cleanliness level
Mode: Abrasive wear of linear guideway surfaces increasing friction coefficient from 0.002 to 0.015
Strategy: Integral wiper seals with 10 μm filtration, positive-pressure purge system maintaining 0.1 bar overpressure
Trigger Misalignment exceeding 0.05 mm/m cumulative error across travel length
Mode: Edge loading on recirculating ball bearings reducing L10 life from 10,000 km to 1,500 km
Strategy: Laser-aligned mounting surfaces with 0.01 mm/m flatness tolerance, kinematic coupling design with 6-DOF constraint optimization
