Some wooden coasters, such as Leap-The-Dips, do not have upstop wheels and are known as side friction roller coasters.

Additionally, the 1NR-VE features longer ports in its intake system for improved low-and mid-range torque, and a low-friction roller rocker arm-based valvetrain for improved fuel efficiency.

To avoire infringement on Edison's motion photo patents, the Mutograph camera used continuous movement friction rollers to move 68 mm film into the camera, instead of intermittent movement by sprockets as Edison's 35 mm camera did.

The shuttle is thrown by two levers attached to the side frame, but activated by a friction roller on the tappet shaft . As the shuttle enters the shuttle-box at the end of its travel, it depresses a lever which acts as a brake.

In the 1720s, the English clockmaker Henry Sully invented a marine clock that was designed to determine longitude : this was in the form of a clock with a large balance wheel that was vertically mounted on friction rollers and impulsed by a frictional rest Debaufre type escapement.

Modern electronic limiters at the very least require replacing the friction rollers in a scooter's CVT transmission, or even changing wheel size and / or reprogramming the engine management system, all in an effort to fool the sensors into detecting a lower than actual road speed.
7.
Valves are driven by roller-follower rocker arms with low friction roller bearings, and a unique, concave cam lobe design to increase valve lift over the traditional shimless lifter type system of the 1GR-FE . This increases overall cylinder head height to accommodate the slightly taller roller rocker system.
