By constantly updating its range of innovative linear axes, Bosch Rexroth has been leading the field for more than 30 years. Thanks to our extremely wide and varied range of products and services, we’re a leading provider in all sectors and for all linear motion technology applications. As a technological leader, we’ve been setting milestones for decades and our customers benefit from our wealth of experience
Linear motion systems are precise, ready-to-install guide and drive systems with high performance features in compact dimensions.
Rexroth Actuators
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.
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
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
