IR16 Irreversible Locks Bidirection Custom Made Bearings
Features
Irreversible Locks IR are bidirectional acting roller freewheels with bearing support. They are ready for installation.
The Irreversible Locks IR are used as:
➧ Bidirectional Acting Backstops
Nominal torques up to 100 Nm.
Bores up to 35 mm.
Whereas a normal Freewheel transmits torques from the driving or driven side in only one irection of rotation, with the Irreversible Lock IR it is possible for the driving part to drive the
shaft in both directions of rotation. There is, ho-wever, a locking action against any reverse tor-que coming from the driven part, irrespective of the direction of rotation in which it is exer-ted.
Dimensions and Capacities
Freewheel Size | Type | Nominal torque | Bore d mm | A* mm | B* mm | C mm | D mm | E mm | G** | L mm | M1 mm | M2 mm | N mm | O mm | P mm | Q mm | R mm | T** mm | V mm | Z** | Weight kg |

The maximum transmissible torque is 2 times the specified nominal torque.
* Keyway according to DIN 6885, page 1 • Tolerance of keyway width JS10.
** Z = Number of tapped holes G on pitch circle T.
Mounting and Coupling
The valve, which in the example shown is a control or shut-off
valve, is adjusted in the opening or closing direction by means of
a handwheel.
The Irreversible Lock prevents any uncontrolled shifts in the
position of the valve due to the pressure exerted by the medium
flowing in the pipe.
The use of Irreversible Locks is not restricted to manually
operated valves and they can also be used with motorised adjusters.
In this case there is the particular advantage that the torque
motor need be designed to supply only the adjusting torque, which
is generally low, since all standing and sudden reverse torques are
absorbed by the Irreversible Lock.
