Bosch Rexroth: Tightening Spindles

Tightening Spindles 

The modular construction of Rexroth tightening spindles enables a very precise adjustment to the tightening task at hand. Conformity with the VDI standard ensures that your tightening connections meet the highest safety requirements. The versatility of Rexroth tightening spindles not only guarantees safety but also a perfect design customized to your needs. Simply choose the size and performance characteristics based on your application requirements. All individual components are fully tested and certified for quick installation without the need for specialty tools.

  • Modular design, ideal adjustment to tightening case 
  • Maintenance-free for 1 million full-load cycles, long service life 
  • Process reliability and minimal waste thanks to real redundancy measurement 
  • Digital measurement transfer, maximum precision 
  • Largest working range 
  • Assured accuracy within the working range according to VDI/VDE 2647
  • Brushless DC Servo Motors offer powerful & quiet smooth operation with no maintenance
  • Fully encapsulated planetary gearboxes offer the highest accuracy and durability. Multiple options for each motor provide high speed or high torque performance
  • Maintenance free digital transducer technology provides accurate and reliable results without the need for recalibration due to EMC or cable wear
  • Robust Industrial grade output drives with 50mm spring compression & standard square drive socket termination

Maximum flexibility in tightening spindle configuration – here are just some of the many options:

TIGHTENING SPINDLE WITH ANGLE HEAD 

  • For high accessibility 
  • Also available with integrated measurement transducer

TIGHTENING SPINDLE WITH OFF SET OUTPUT DRIVE 

  • For side-by-side arrangement with small center-to-center distances 
  • Also available with integrated measurement transducer

TIGHTENING SPINDLE WITH TRANSVERSE GEARBOX 

  • Compact length 
  • Available for all sizes

TIGHTENING SPINDLE WITH FEED OUTPUT DRIVE 

  • Integrated feed movement 
  • For use in connection with automatic bolt supply

Configure your tightening spindle

NUMEROUS OPTIONS 

With a working range between 0.6 and 1,000 Nm (higher torques on request) and a choice between straight output drives, offset output drives, feed output drives, and angle heads – with Rexroth components you can configure a tightening spindle that is customized to your individual requirements. 

We offer the offset output drive and angle head also with an integrated measurement transducer. You can decide between having just one measurement transducer or working with an additional second redundant one. We can provide the optimum spindle components for any task. Why not find the perfect tightening spindle for your tightening connection?

OUTPUT DRIVES 

  • The suitable output drive for every tightening position 
  • Special output drives for increased transverse forces, e.g. for wheel nutrunners, on request

ADAPTER A 

  • Connects planetary gearbox and output drive when operating without a measurement transducer

AVR REDUNDANT ADAPTER 

  • Connects an offset output drive with integrated transducer to a measurement transducer

AVG ADAPTER 

  • Connects an offset output drive with integrated transducer to a planetary gearbox when operating without a redundant measurement transducer

MEASUREMENT TRANSDUCER 

  • Non-contact, maintenance-free sensors 
  • Direct analysis of torque, angle of turn, and gradient 
  • Integrated, load-dependent cycle counter 
  • Can also be used as a redundant transducer for further safety

AR REDUNDANT ADAPTER 

  • Connects two measurement transducers

PLANETARY GEARBOX 

  • Several gearboxes per series for optimum adaption to the tightening joint

TRANSVERSE GEARBOX 

  • Reduction of installation length

EC MOTOR 

  • Reliable 
  • Short tightening times 
  • Excellent dynamics 
  • High RPM 
  • Side-by-side arrangement due to small outer dimensions 
  • High density and power efficiency
