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.

• 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

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?
