Typical Applications
BH Series Rotary Assembly
BH Series

The BH Series rotary assembly machine features an indexing dial plate with synchronized pick & place or pressing handlers mounted above the indexing dial plate. Driven with one motor, up to (12) pick & place and/or pressing handlers can mount in any combination or angular position around the bull gear drive. For accurate positioning at high speeds with a small footprint, this is the ultimate assembly machine. Just add finger tooling, station fixtures and power.


Speed & Accuracy
  • Up to 90 cycles per minute
  • Less than ±30 arc seconds indexing dial plate positioning accuracy
  • Less than ±0.02mm (±0.0007”) handler positioning accuracy
Synchronized Rotary & Linear Motions
  • 6, 8, 10, 12, 16, 18, 20, 24, 30 or 36 indexing stations
  • Up to 12 pick & place and/or pressing handlers of any combination
Standard Features
  • Totally assemble with drive system, handlers, indexing dial plate, manual rotation & base frame
  • 2 torque limiting clutches to protect motor & handler drives with overload detection
  • Synchronized output line shaft drive to power supporting equipment
  • Base plate with radial T-slots for mounting supporting equipment
  • Dual timing cam flags & proximity switches
  • Finger safe guarding (excluding the handler motion)
  • Dual voltage (230 or 460) inverter rated motor
  • Linear torque limiter for each pick & place handler (LM Series...more)
  • Rotary torque liming clutch for rotary indexing dial plate (To Series...more)
  • Rotary encoder for motion timing
  • Variable speed motor controller (VFD)
  • Servo motor drives for frequent on demand cycling
  • Custom base plate & frame configurations
  • Dual assembly machines in a common from with rotary transfer handlers between dial plates
Small Footprint
  • Footprint is much smaller than conventional assembly machines
  • Replaces short conveyor applications with better accuracy & capacity
