In cases where backlash must be minimized, a smooth, toothless ratchet with a high friction surface such as rubber is sometimes used.

The brake shoes in those systems have a backing plate to which the friction surface is glued or riveted.

As the name implies, a cone clutch has conical friction surfaces.

His company developed friction surfaces for vehicle braking systems.

Roman stopped to examine the high friction surface they were walking on.

There are various friction surfaces through the game, increasing or decreasing traction of the marble rolling on them.

These synchronizers have three friction surfaces, which increase their ability to transfer the flow of torque more smoothly from one gear to another.

All of the friction surfaces on the synchronizer rings are sintered bronze.

As an additive in glide wax for skiis, and other low friction surface materials.

It provides traction even on low friction surfaces.
