Servo Press Systems

Bushing Press Systems

rpGatta’s high reliability bushing presses are custom designed to quickly and accurately press bushings into sub frames:

  • Flexible system is capable of handling multiple frame and bushing variations
  • Multiple servo press assemblies utilize force and distance monitoring to ensure reliable placement
  • Orienting the frame at a slight angle allows one operator to ergonomically load the frame and bushings
  • Error proof bushing placements ensures that the operator places the correct bushing in the correct orientation
  • PLC controls, Operator HMI, and light curtains ensure maximum safety and equipment up time


Pinion Press


  • Utilizes 2 FEC servo presses to press fit each pinion gear on two A-Shield motor shafts
  • Full press reaction force is contained within the equipment by attaching to the A-Shield motor shaft tapped hole with custom spindle
  • +/- 2mm of X-Y float designed into press tooling to account for pallet and part variance
  • Equipment bottoms out on top surface of motor shaft to set datum for accurate press distance data

Gearbox Assembly Line Presses


  • The conveyor transfers pallets from station to station
  • Manual stations in between press stations where operators can load parts
  • Each of the (8) custom servo presses installs a different part

Floating Press Tooling


  • Press tooling designed to retain intermediate and output outer races onto pilot
  • +/- 2mm of X-Y float designed into press tooling to account for pallet and part variance
  • Intermediate press tooling bottoms out on press surface and compresses to avoid interference
  • Sensors added to ensure TRB’s are fully seated on press tooling
  • Guarding added around front sensors to prevent operator interference
  • Compressive tooling piloted by an oil embedded (self-lubricating) flanged bronze bushing and hardened shaft
  • At full press the compressive tooling pilot will retract allowing tooling to not interfere when pressing the bearing into the C’Bore
  • Once the ram starts to retract a spring will force the pilot back to its starting position
  • The parts are offset so pilot will compress and bottom out on pressing ram before over compressing the spring
