RODOGRIP®
RODOGRIP® precision locknuts feature a compact and solid construction, they can be locked on a threaded shaft by their built-in tightening system, so there is no need for additional washer, jam-nuts or securing devices.
Distinctive feature
The RODOGRIP® precision locknuts are used to keep bearings or other components firmly positioned onto threaded shafts. They are the ideal devices for position adjustement and for preloading axial and conical roller bearings, either singly or in combination.
The locking nuts can also hold any pulley, torque limiting couplings or recirculation ball screws in their assigned position.
Applications
In the construction of machine tools, and particularly of spindles and power drives, there is a strong demand for means to ensure an accurate, reliable and space-saving locking action and all of above can be satisfied by the RODOGRIP precision locking nuts.
Advantages
- compact build-up, high geometric accuracy
- non need for additional securing devices or keyways machined on shaft
- they do not mark or deform the thread on the shaft
- quick installation and accurate setting
- reliable gripping action on shaft
- low locking torque for a permanent grip
- etting axial clearance of bearings performed accurately and quickly
Functional structure
RODOFLEX flexible couplings are used in CNC machine tools, both for coupling motion controlle devices and for effective power transmission.
The couplings’s flexible element is the metallic bellows which can tolerate angular and parallel misalignment, compression and traction, while remaining torsionally stiff. The torsional stiffness is the most important feature of the RODOFLEX flexible couplings; there are no clearance, back-lash or position transmission errors.
The metallic bellows being the flexible element, the construction is compact and lightweight. It has a good mass/torque ratio and therefore a limited moment of inertia, which is useful in applications with high acceleration, rotation sense reversal and high rotation speed.
Beside the standard production range presented in this catalogue, manufacturing of special units may be accomplished.
