Compact worm-gear goniometers for precise tilt adjustment in space-limited instruments and automation equipment.

TBG series motorized goniometers are compact tilt stages for applications with limited space and high operating rates. A finely ground steel worm drives a wear-resistant tin bronze worm gear, and a two-phase 42 stepping motor provides fine resolution and positioning. TBG45-60 and TBG80-60 run on arc V-shaped ball guides, while TBGX100-80 and TBGX140-80 use arc crossed-roller guides; rotation center heights range from 45 mm to 140 mm.

Key Features

  • Ground steel worm and wear-resistant tin bronze worm gear for long-term durability
  • Arc V-shaped ball guides (TBG45-60, TBG80-60) or arc crossed-roller guides (TBGX100-80, TBGX140-80)
  • Four rotation center heights: 45, 80, 100 and 140 mm
  • Repeatability ≤ ±0.005° and reverse clearance ≤ 0.01° on all models
  • Swing accuracy at the rotation center ≤ 0.01 mm
  • Two-phase 42 stepping motor, 1.8°, 1.7 A; stepping driver optional
  • Built-in limit (2) and origin (1) sensors; DB9 connector with 0.2 m high-flex cable

Typical Applications

  • Integration in automation equipment and instruments
  • Production lines with limited motion space and high repetition rates
  • Tilt alignment of optics, samples and detectors
  • Angle-dependent optical measurements
