Rexroth Actuators

SBL Linear Actuator

SBL Linear Actuator

The ServoBelt Linear Motion Actuator (SBL) provides machine builders with new levels of adaptability and customization when designing machines with linear axes, including: multiple independent carriage travel, limitless carriage travel, along with High Performance.

As a result from its unique fixed-belt design, the SBL provides new machines with the precision and performance typically seen with linear motors, but at conventional belt-driven module value.

Applications:

  • Machine Tending
  • Pick-and-Place
  • Palletization
  • Material Shuttling
  • Mold Loading/Unloading

Ideal For:

  • Automated storage and retrieval
  • Secondary process packaging and labeling
  • Semiconductor wafer metrology (below plane applications)
  • Biomedical instrumentation
  • Laser cutting and processing
  • Large format printing and finishing
  • Injection molding

Key Benefits:

  • Backlash-free performance with high accuracy
  • Multiple carriage options on one linear axis provides higher design flexibility
  • Limitless scalability and independent carriage operation allows large format design translating to better value for each machine
  • Free selection of motor allows customers to use preferred option

Notable Features:

  • Constant belt tension only around the pinion prevents stretching of the belt
  • Dual belt design uses a permanent belt bonded along the extrusion length combined with the active belt inside each individual carriage allowing near limitless travel distance and multiple carriage options for each axis
  • Speeds up to 4 m/s and accuracy +/- 4 µm per meter
  • Rexroth motors operate 200:1 inertia mismatches due to our high driveline stiffness

SBR ServoBelt Rotary Motion Actuator

SBR ServoBelt Rotary Motion Actuator

The ServoBelt Rotary (SBR) stage is a series of compact, high-torque rotary stages that offer through hole size and speed comparable to more expensive direct-drive rotary tables. With the addition of the ER-16 and ER-25 collet closers, the SBR Rotary is the easiest rotary stage to integrate into machines requiring collet closing functionality.

Applications:

  • Labeling
  • Indexing
  • Carousel Tables
  • Tool Switching

Ideal For:

  • Testing and Measurement
  • CNC Machining
  • Secondary Packaging
  • Injection Molding

Key Benefits:

  • Economically priced stages with additional collet closers provide additional machine flexibility
  • Better performance and less downtime thanks to the longer bearing life
  • Easier to integrate as a result of the numerous through hole and motor configuration options
  • Continuous rotation of the stage adds application flexibility
  • More design freedom thanks to additional accessories like collet closers, and open selection of motors and controls

Notable Features:

  • Large through holes provide useful passage of cables and other apertures
  • Angular bearing design supports higher load capacities

Rexroth motors operate 200:1 inertia mismatches due to our high driveline stiffness.
