Tolomatic RSA-HT High Force RSA Electric Actuator (UP TO 57,000N FORCE)

RSA-HT High Force Actuator is a basic yet high performance electric screw-driven, rod-style actuator

The RSA-HT series electric rod actuators from Tolomatic offer the most complete selection of sizes, options and system components. Designed with high performance, high thrust, dependability and mounting flexibility in mind, the RSA-HT electric rod actuator offers the thrust capabilities up to 57,392 N with the stroke length up to 1,524mm, which is a cost-competitive solution for a multitude of motion control applications.

  • 6 body sizes
  • 35 different screw selections
  • Force capabilities up to 12,900 lbf (57,392 N)
  • Strokes in any incremental length up to 60 in (1,524 mm)
  • US customary and metric versions


  • Higher strength components transfer torque from the gearhead/motor through the actuator
  • Grease nipple allows convenient relubrication for extended screw service life
  • Allows convenient addition of gearbox to RP (Reverse Parallel mount) actuator
  • Accommodates mounting large motors up to 165mm diameter and IP67 protection for outdoor applications


Redesigned LMI & RP Housing

  • Available on all inline and 64 size RP mounts. Specially designed to accommodate larger motors & gearboxes with higher torques and larger bolt circles (up to 6.5", 165mm)

Durable Belt Material

  • High torque polyurethane timing belt with carbon tensile cords resists stretching

Enhanced High Thrust Bearing

  • Available on 64 size and roller screw actuators. High thrust angular contact ball bearing in matched pair assembly design eliminates runout and isolates the linear forces for the drive shaft

Heavy Duty Internal Bumpers

  • Bumpers protect screw and nut assembly from damage at both end of stroke

IP67 Protection

  • Resist water ingress 1m deep for up to 30 minutes

Grease Zerk

  • This relubrication system provides extended screw service life
  • Convenient lubrication without disassembly
  • Standard with all HT option RSA actuators

Threaded Rod End

  • Provides a common interface to multiple rod end options
