1.5 Environmental protection
Energy: The one-way clutch does not use any electrical energy
Materials: Steel
Recycling: Steel parts are up to 100% recyclable
2.1 Intended use
One-way clutches of type RSXM31-RSXM101 are directional clutches, engaged and
disengaged automatically, depending on the relative direction of rotation.
The torque is transmitted by a force-locking connection. They can be used as overrunning
clutches or backstops in machinery and equipment.
Driving operation of an overrunning clutch:
When operating in torque transmission mode the driving machine element and the driven
member are connected in a force-looking manner. In this operating state, a torque will be
transferred.
Overrunning operation of an overrunning clutch:
The overrunning clutch disengages automatically when the driven member rotates faster
than the driving member.
The contact-free operation will be ensured, when the driven member connected with the
inner race runs above a defined speed. From this speed up the wear-free operation of all
function-relevant components is guaranteed.
Lockout mode of a one-way clutch:
When operating in the locking direction of the one-way clutch, the machine shaft and the
torque bracing to the machine element are connected in a force-looking manner.
In this operating state, a torque will be transferred.

3.1 Structure
Fig. 1 Structure
3.2 Function
When the torque is transmitted through the one-way clutch, the outer race (1) and the inner
race (2) are coupled in a force-locked manner (see Fig. 2). For this purpose, clamping
elements are used, the outer contours of which generates the force-locked coupling. The
clamping elements are integrated into a cage (8) and are energized by springs into contact
with the outer and inner race. The springs ensure rapid responding behavior of the one-way
clutch at the start of torque transmission.

Fig.2 Torque transmission
In overrun operation, above the minimum permissible overrunning speed, the centrifugal
force, in connection with the geometry of the clamping elements, generates a force which
turns the clamping elements against the spring force (see Fig. 3). A contact-free position is
brought about in this way so that wear-free operation of the one-way clutch can be achieved.
The minimum permissible overrunning speed may only be lower for a short period during the
start-up or shut-down stage otherwise the damage to the contact partner caused by wear
and tear may lead to the failure of the one-way clutch.
Fig.3 Contact-free position
NOTE The local provisions regarding the disposal of transport and
packaging materials are to be observed.
One-way clutches of Type RSXM31-RSXM101 are packaged in non-absorbent corrosion
protection paper. All components are sent in a box.
To prevent the component from breaking or falling apart they are fixed with a cable clip.

WARNING
Risk of injury due to incorrect assembly!
Faulty installation and maintenance can cause severe property
damage and personal injury.
Installation, maintenance and repair work may only be performed
by personnel with the requisite training and expertise.
WARNING
Risk of injury due to moving components!
Rotating driven components can cause the most severe injuries.
Therefore, during operation:
It is strictly forbidden for persons to loiter in the danger zone
or in its immediate vicinity.
Do not disable, render unusable or circumvent safety
equipment and / or safety functions.
Prior to entering the danger zone:
Switch off the power supply and secure it against being
switched on again.
Wait for lagging components to come to a standstill.
CAUTION
Risk of injury due to falling components!
The outer race or inner race can fall down if the transportation lock
has been removed.
Fasten the outer / inner race axially.
The direction of rotation at idle speed is marked as FREE on the cage (8). The direction of
rotation can be changed by turning the inner race (2) including cage (8).
Procedural steps:
Place the one-way clutch facing upward the label "FREE" on an assembly table
Remove the cable clip
Lift the inner race (2) including the cage (8) out of the outer race (1). Use
appropriate lifting gear at the threaded hole of the inner race for this
Place the inner race (2) including the cage (8) facing downwards the label "FREE"
on an assembly table
Secure (see Fig. 4 and 5) the clamp bodies in lift-off position (against the spring
force) using an O-ring / cable connector as an assembly aid
6 Installation

Stieber Clutch Page 12/21
M1016E_0 Assembly and maintenance manual
Insert the inner race (2) with cage (8) into the outer race (1) until half of the clamp
body is covered
NOTE
The assembly aid (O-ring / cable connector) must be completely
removed. Non-observance of this note can cause functional
impairment and even failure.
Remove the assembly aid (O-ring / cable connector) completely and lower the inner
race and cage completely.
Check overrunning. The one-way clutch must be able to be turned easily in the
overrun direction of rotation.
6.2 Lubrication
One-way clutches of Type RSXM31-RSXM101 do not require any lubrication in overrun
operation above the lift-off speed as they operate without contact.
Similarly, no lubrication is required in lockout operation as only a minimal degree of rolling
motion in the clamp bodies occurs.
Additional lubrication is required if the one-way clutch runs with frequently repeated or
permanent working cycles below the lift-off speed. To this end, a lubricating film, which coats
the clamp bodies and tracks of the outer race, is mandatory. The lifetime is limited under
these operating conditions!
6.2.1 Operation with oil lubrication
An oil mist is sufficient for mounting inside a gear box.
If the one-way clutch runs with frequently repeated or permanent working cycles below the
lift-off speed, splash lubrication or oil supply between the cage and the outer track is
necessary. The lifetime is limited under these operating conditions!
The oil volume which is necessary for splash lubrication depends on the surrounding
construction.
