generation on either side of clutch disc has been modelled separately.
Integrated bearings in hybrid technology lower the starting torque and frictional torque
in operating speed in comparison to air bearing separator rollers known for their low friction.
Some seals last 10 times longer than others in lab testing, but better sealing typically increases drag and frictional torque
, which can be undesirable in some applications.
Dutch firm Royal DSM has launched an innovative new high-performance material that reduces frictional torque
in automobile engine timing systems.
Natsumeda and Miyoshi  carried out theoretical analysis on the engagement of wet clutch on the basis of two-dimensional average flow model for the analysis of oil film squeeze motion and mainly analyzed the effect of temperature on the frictional torque
of wet clutch engagement.
j] = summation of all of the frictional torque

The obvious solution was a stronger spring, but that increases decoupling effort and frictional torque
, both of which are bad in a medical syringe pump.
Sir John Charnley was convinced that the frictional torque
from the MOM articulation was unsatisfactory and the cause of the failures of the early McKee prothesis.
At the same time, the disc is rotated and the shear stress is determined from measurements of the frictional torque
at each stress level.
Within the 4-point contact radial ball design, one-piece separators between balls maintain low frictional torque
These seals have poor wear resistance and high frictional torque
, which consumes a lot energy, particularly at startup when dry sliding environment prevail.
