An "R Cam" is a mechanical component primarily used in elevator systems, specifically within the braking mechanism, which functions as a safety feature to ensure controlled stopping of the elevator car in emergency situations; its key parts include the R Cam coil (the rotating cam itself), the plunger (which engages with the cam to activate the brake), and sometimes a guide or bearing to ensure smooth movement; it is often made from materials like mild steel or stainless steel depending on the application.

Key details about R Cam parts:

Function:

The R Cam design is designed to quickly engage the brakes when needed by creating a sudden displacement when the coil rotates, pushing the plunger against the brake mechanism. 

Components:

• R Cam Coil: This is the main rotating part with a specially designed profile that creates the necessary cam action when rotated. 
• Plunger: A cylindrical component that fits into the cam groove on the coil, pushing against the brake actuator when the cam rotates. 
• Guide/Bearing: Some R Cam designs may include a guide or bearing to ensure proper alignment and smooth movement of the plunger. 

Material:

•         Mild Steel: Commonly used for basic R Cam applications due to its affordability and good mechanical properties. 
•         Stainless Steel: Preferred for environments with high corrosion potential, ensuring longer lifespan. 

Application:

Elevator Safety Systems: Primarily used in elevators to activate the brakes during overspeed situations, sudden stops, or in case of power failure.
