Product catalog summary
Overview
The Model 16J is a precision horizontal balancing machine designed for high-precision applications in gas turbines, including aircraft armatures, shafts, and other turbine components. It utilizes hard-bearing technology and force-measuring transducers for accurate unbalance measurement.
Key Features
  • Rugged piezo-electric transducers that are unaffected by temperature or humidity and are sealed against dust and dirt.
  • Fully traversable work supports along a precision-machined bed with a gear-rack system for parallel alignment.
  • Adjustable end-thrust assemblies with precision ball bearings for axial load acceptance in belt-drive systems.
  • Pneumatic belt-tensioning system ensuring consistent drive-belt pressure.
  • Optional safety guard meeting OSHA and/or CE requirements.
  • Custom hardware and software options available.
Technical Specifications
  • Configuration options: End drive, Belt drive, Belt/End drive.
  • Maximum rotor weight: 120 kg (265 lb).
  • Maximum rotor diameter: 780 mm (31 in).
  • Balancing speeds: 60 - 1750 rpm, rotor dependent.
  • Accuracy: Displacement of C.G. ≤ 0.38 µm (≤ 15 µin).
  • Sensitivity: ≤ 0.38 gmm/kg.
  • Unbalance reduction ratio: 95%.
  • Power: 1 hp AC motor.
  • Electrical characteristics: 230 V, 3-phase, 60 Hz or 380 – 440 V, 3-phase, 50 Hz.
  • Meets SAE ARP 4048 Specifications for Horizontal Machine Class 100.
