Industry
High-torque, high-rigidity shaft couplings and high-strength screws for the machine tool industry: precision drive trains and positioning axes.
Overview
The machine tool industry with their precision drive trains depend on couplings that transmit torque accurately and hold their position under load. Any backlash or torsional wind-up shows up directly as positioning error, so servo and stepper axes need zero-backlash, torsionally stiff connections. NBK Europe supplies high-torque, high-rigidity shaft couplings and high-strength special screws engineered for demanding motion and drive applications.
Bellows and disc couplings combine zero backlash with high torsional rigidity for accurate servo positioning, while jaw and rigid types handle high torque and general drive duty. High-strength fasteners keep assemblies secure under vibration and load. Full specifications and CAD files are available per product on nbk1560.com. Tell us your torque, speed and accuracy targets and we will match the right coupling.
These machines run 24/7 with very short tool change times. They combine high-speed, dynamic movements at high precision with long-term reliable performance. Here high-gain couplings of the XG series are used, as they enable a reduction in settling times and rapid absorption of vibration with zero backlash.
For this customer the requirement was high speed and precision positioning. They offer a turnkey solution for battery assembly including automated unpacking of incoming material, casing assembly, PCB assembly, laser welding, testing and final-product testing. This customer was able to improve production throughput and quality, key aspects in battery production. A combination of shaft couplings and special screws was used: the focus for the couplings was high torsional rigidity, and the XHW disc-style coupling was selected, alongside slit coupling MSX-C and high-strength screw SNSLG-TF.
High torsional rigidity for accurate positioning.
Transmits large drive forces without slip.
Lost-motion-free transfer for servo and stepper drives.
Zero-backlash stainless-steel disc coupling with very high torsional stiffness for high-speed, high-precision servo and stepper positioning.
Compact cross-joint coupling with high torsional stiffness, minimal backlash and symmetric CW/CCW characteristics for servo and stepper drives.
Zero-backlash elastomer coupling that combines high torsional stiffness with superior vibration and shock damping, ideal for dynamic servo drives.
One-piece slit couplings for cleanroom, vacuum and heat-resistant use: zero backlash, low particle generation and excellent chemical and corrosion resistance.
One-piece spiral-beam slit couplings for precise speed and position control: zero backlash, high torsional stiffness, in aluminium or stainless steel.
Thin-walled metal bellows coupling for exceptional positioning accuracy: zero backlash and constant-velocity rotation with very low reaction forces on bearings.
Elastomer-jaw coupling that transmits high torque while absorbing vibration and misalignment: zero backlash with tight-fit sleeves and electrical insulation.
Zero-backlash couplings with high torsional rigidity, such as bellows and disc types, are preferred for servo axes because they transmit motion without lost angular play and keep positioning accurate under load.
Zero backlash means there is no lost angular play between the shafts, so commanded motion is transferred one-to-one. This prevents positioning error and is essential for precise machine-tool and positioning drives.
Yes. High-strength and high-tensile special screws are available for assemblies that must stay secure under vibration and heavy load, with full specifications on nbk1560.com.
