Stepping Actuator

  • S1 Stepping Actuator

    S1 Stepping Actuator

    S1 stepping actuator
    S1 Single Rack Stepping Actuator

    Overview

    The S1 is our smallest stepping actuator but it shares the same traits of its larger counterparts. The S1 provides unidirectional rotation in increments but unlike our X1 Indexing Actuator, it does not have positive stopping capability. The load will coast to a stop unless acted on by an external force. Unlike competitive products with add-on clutch housings, the S1 has a fully integrated clutch-bearing assembly for solid support of the load.

    Specifications:

    • Bore Size = 5/8"
    • Standard Rotations = 15 Angles from 30 to 730 degrees
    • Shaft Sizes = Standard: .375" dia., Options: None
    • Torque at 80 psi = 12 in-lbs.
    • Ball Bearing Ratings = Radial: 305 lbs., Axial: 76 lbs.
    • Port Size = 10-32 or 1/8 NPT
    • Available Options:
      • Adjustable Rotation
      • Cushions
      • Flow Controls
      • Mount Plates
      • Bumpers
      • Hydraulic Service Seals
      • Fluorocarbon Seals
      • Fluorocarbon Hydraulic Service Seals

    See the S1 Rotary Actuator Part Number page for detailed configuration and option information.

    For increased torque output, consider our S2 Stepping Actuator.

  • S2 Stepping Actuator

    S2 Stepping Actuator

    S2 stepping actuator
    S2 Single Rack Stepping Actuator

    Overview

    The S2 stepping actuator is ideal for use in relatively small index tables with shot pins, conveyors, or as drives for roll feeders. The S2 provides unidirectional rotation in increments but unlike our X2 Indexing Actuator, it does not have positive stopping capability. The load will coast to a stop unless acted on by an external force. Unlike competitive products with add-on clutch housings, the S2 has a fully integrated clutch-bearing assembly for solid support of the load.

    Specifications:

    • Bore Size = 1"
    • Standard Rotations = 15 Angles from 30 to 730 degrees
    • Shaft Sizes = Standard: .500" dia., Options: D .500" dia.
    • Torque at 80 psi = 39 in-lbs.
    • Ball Bearing Ratings = Radial: 1,030 lbs., Axial: 257 lbs.
    • Port Size = 1/8 NPT
    • Available Options:
      • Adjustable Rotation
      • Cushions
      • Flow Controls
      • Mount Plates
      • Bumpers

  • S3 Stepping Actuator

    S3 Stepping Actuator

    S3 stepping actuator
    S3 Single Rack Stepping Actuator

    Overview

    The S3 stepping actuator is ideal for use in medium index tables with shot pins, conveyors, or as drives for roll feeders. The S3 provides unidirectional rotation in increments but unlike our X3 Indexing Actuator, it does not have positive stopping capability. The load will coast to a stop unless acted on by an external force. Unlike competitive products with add-on clutch housings, the S3 has a fully integrated clutch-bearing assembly for solid support of the load.

    Specifications:

    • Bore Size = 1 3/8"
    • Standard Rotations = 15 Angles from 30 to 730 degrees
    • Shaft Sizes = Standard: .750" dia., Options: None
    • Torque at 80 psi = 119 in-lbs.
    • Ball Bearing Ratings = Radial: 1,030 lbs., Axial: 257 lbs.
    • Port Size = 1/4 NPT
    • Available Options:
      • Adjustable Rotation
      • Cushions
      • Flow Controls
      • Heavy Duty
      • Washdown Protection
      • Mount Plates
      • Magnetic Switches (Installed & Tested Prior To Shipping)

      • Fluorocarbon Seals
      • Fluorocarbon Hydraulic Service Seals

    See the S3 Stepping Actuator Part Number page for detailed configuration and option information.

    For increased torque output, consider our S4 Stepping Actuator.

    Possible to add independently-controlled linear motion, like PA3 Pick & Place Actuator but with stepping rotary section.

  • S4 Stepping Actuator

    S4 Stepping Actuator

    S4 stepping actuator
    S4 Single Rack Stepping Actuator

    Overview

    The S4 stepping actuator is ideal for use in medium to large index tables with shot pins, conveyors, or as drives for roll feeders. The S4 provides unidirectional rotation in increments but unlike our X4 Indexing Actuator, it does not have positive stopping capability. The load will coast to a stop unless acted on by an external force. Unlike competitive products with add-on clutch housings, the S4 has a fully integrated clutch-bearing assembly for solid support of the load. With over 10 times the maximum torque capacity of the S1 Stepping Actuator, the S4 is not only the largest single rack stepping actuator in our lineup but also a heavy hitter among its kind.

    Specifications:

    • Bore Size = 2"
    • Standard Rotations = 15 Angles from 30 to 730 degrees
    • Shaft Sizes = Standard: 1.000" dia., Options: D 1.000"
    • Torque at 80 psi = 277 in-lbs.

  Actuator Motion Options

Choose your motion then configure the unit to suit your needs exactly.

Rotary Actuators Configured for Your Application
At Rotomation, we manufacture high-speed, heavy-duty pneumatic, and low-pressure hydraulic rotary actuators with various shaft motions. Our design and engineering team will get you the product that fits your requirements. Choose rotation options from a bidirectional rotation between two, three, four, or five positions, and unidirectional rotation in steps. Each rotary motion can be combined with linear motion in a single, independently-controlled actuator.
Our actuators are used in applications for metalworking, assembly, testing, and packaging machinery for automotive, semiconductor, food, pharmaceutical, and other industries.
Their customization and configurability mean you can specify an actuator that will optimize the design of your machines.
