» Rodogrip - General Features



The RODOGRIP precision locking nuts are used to keep bearings or other components firmly positioned onto threaded shafts. They are the ideal devices for position adjustement and for pre-loading axial and conical roller bearings, either singly or in combination. The locking nuts also can hold any pulley, torque limiting couplings or recirculation ball screws in their assigned position.

In the construction of machine tools, and particularly of spindles and power drives, there is a strong demand for means to ensure an accurate, reliabale and space-saving lockin action and all of above can be satisfied by the RODOGRIP precision locking nuts.



The RODOGRIP precision locking nuts have a solid and compact design; they can be locked on the shaft by means of their integrated locking system, without the need for counter ring nuts, washer or keyways on the shaft. After screwing the locking nut on the shaft in the required position, three steel set hex socket screws placed radially around the outer circumference of the RODOGRIP nut must then be screwed.

These set screws press on brass brass tips, which, in turn, press directly on the threaded shaft. The surface of the brass tips is duly shaped and aligned with the trend of the thread on the locking nut and shaft. This most important feature ensures a reliable and firm locking action.
