Description

A rotor retainer is a component used in a rotary engine to hold the rotor in place. A rotary engine, also called a Wankel engine, uses rotors instead of traditional pistons to generate power. The rotor retainer is a small metal clip that fits on the end of the rotor and securely holds it on the shaft.

Features

  • Designed to withstand high temperatures.
  • Holds the rotor securely in place.
  • Withstands high stress.

Applications

The rotor retainer is an essential component in the operation of a rotary engine, because the rotor could otherwise come loose and cause serious engine damage.
