Thrust bearings are also used with radio antenna masts to reduce the load on an antenna rotator. One kind of thrust bearing in an automobile is the clutch "throw out" bearing, sometimes called the clutch release bearing. [4] [clarification needed] [5] [6]

Mechanical device that connects and disconnects two rotating shafts or other moving parts For other uses, see Clutch (disambiguation). Friction disk for a dry clutch A clutch is a mechanical device that allows an output shaft to be disconnected from a rotating input shaft. The clutch's ...
One-way bearing combining sprags and bearing rollers in one race Sprags jam when driven and slide when in reverse. A sprag clutch is a one-way freewheel clutch.It resembles a roller bearing but, instead of cylindrical rollers, non-revolving asymmetric figure-eight shaped sprags, or other elements allowing single direction rotation, are used.
These valves have been unpopular with some drivers and are sometimes removed in favour of a conventional clutch action. [2] The BMW valve takes the form of a separate pipe fitting and is easily removed. Honda has also used clutch delay valves on some Civic models, which are integral to the clutch slave cylinder and must be dismantled in situ. [3]
Although bearings tend to wear out with use, designers can make tradeoffs of bearing size and cost versus lifetime. A bearing can last indefinitely—longer than the rest of the machine—if it is kept cool, clean, lubricated, is run within the rated load, and if the bearing materials are sufficiently free of microscopic defects.
Dual-mass flywheel section. A dual-mass flywheel (DMF or DMFW) is a rotating mechanical device that is used to provide continuous energy (rotational energy) in systems where the energy source is not continuous, the same way as a conventional flywheel acts, but damping any violent variation of torque or revolutions that could cause an unwanted vibration.
The rotary force is transmitted through wedges that fit into two or three open grooves. The bit is free to move a short distance and the hammer action moves the bit up and down within the chuck. Two sprung balls fit into closed grooves, allowing movement whilst retaining the bit. There are four standard sizes with varying shank diameters: SDS Quick
[2]: 64 [3] Full-width aluminium louvre panels across the front lid and engine cover provide airflow through the front-mounted radiators and engine bay. Louvre grilles are located on each side of the vehicle just ahead of the rear wheels providing intake air to the engine on the right and on the left, providing air to an external oil cooler ...
