Cam clutches ensure precise backstopping
Clutches are designed for backstopping operations in light-duty applications at high speeds - typically in fans, air conditioning units and ventilation systems.
New from Tsubaki the MREU (Motor Reducer European) range of cam clutches are designed for backstopping operations in light-duty applications at high speeds - typically in fans, air conditioning units and ventilation systems The new clutches are designed primarily for OEM applications and are competitively priced with a special design of lift-off cams that ensure precise backstopping and optimised speed when overrunning without further contact between cams and races

10 times more wear life than O-ring sealed chain
Tsubaki has launched X-Lambda, a lube-free chain that provides at least 10 times the working life of conventionally sealed "O" ring chains without any significant loss of transmission efficiency
Chain with 30 times the life
Tsubaki's WP chain can provide 30 times the life of standard and nickel plated chains in wet conditions.
MREU series clutches have been introduced to meet the requirements of European machinery and heating and ventilation installations.
Although extremely compact, they integrate a full complement of cams to provide the maximum number of load transmitting members for a given diameter.
This results in a greater torque capacity, size-for-size, than other cam clutches, and longer fatigue life.

The cams in the MREU cam clutch are lift-off type devices, offering the advantage that they are designed to lift off and have no contact with the inner and outer races of the clutch when it overruns.
This feature offers benefits in terms of zero friction, longer wear life and the facility for high speed overrunning.
A typical application of the MREU cam-clutch is extraction fans.
These units can suffer heavy damage if they are rotating in the reverse direction as a result external air currents, when the drive motor is switched on.
The MREU clutch can prevent this problem with its backstopping function, reverse rotation being prevented by instantaneous automatic engagement of the clutch.
Another typical application is for manufacturers of air cooling fans where fans in the same vicinity do not always operate simultaneously.
In this situation, the convection of air current from one fan can make another in close proximity start to slowly rotate in the opposite direction causing component damage or in some cases failure of the reducer or coupling units.
The benefits of using a cam clutch in this type of application means selective operation or function can be achieved, thus reducing repair cost and and importantly, energy costs.
Available in open types for internal installation and packaged types for external applications, the MREU clutches are just one series in a comprehensive range of full complement cam clutches available from Tsubaki.
The cam clutches are designed for convenient press-fit in housings.
They are manufactured in a range of capacities and styles which offer the best functional characteristics for performing general overrunning, indexing and backstopping. Request a free brochure from Tsubakimoto UK ...
