Tensioner and Other Bearings

As a device that prevents the timing chain from wearing out, OHC and DOHC requires long chains for the crank shaft and cam shaft.

When long chains are rotated at a high rotation, they rise up due to the centrifugal force to hit the case, and this device prevents the chains from rising up with springs or hydraulic pressure.
