Pin Configuration

Universal Flange Ball Bearing 4x8x3mm Shielded Chrome Steel Bearings Documentation
Component Overview
The Universal Flange Ball Bearing 4x8x3mm Shielded Chrome Steel Bearings is a type of precision ball bearing designed for high-performance and low-friction applications in IoT devices, robotics, and other mechanical systems. This bearing features a chrome steel construction, shielded design, and a flanged outer ring for easy mounting.
Pinout Description
The Universal Flange Ball Bearing does not have traditional pins like an electronic component. Instead, it has a set of mechanical interfaces that enable its integration into a system. Here is a point-by-point explanation of the bearing's mechanical interfaces:
Inner Ring (ID: 4mm): The inner ring is the rotating component of the bearing that attaches to a shaft or spindle. It has a 4mm inner diameter, allowing it to fit onto a corresponding shaft size.
Outer Ring (OD: 8mm): The outer ring is the stationary component of the bearing that attaches to a housing or mounting point. It has an 8mm outer diameter, which provides a secure fit into a corresponding housing or mount.
Flange (Thickness: 3mm): The flange is a protruding rim on the outer ring that provides a flat surface for easy mounting and securing the bearing to a housing or plate. The flange thickness is 3mm, ensuring a robust and stable connection.
Balls: The balls are the rolling elements within the bearing that facilitate smooth rotation and low friction between the inner and outer rings. They are made of chrome steel, providing high strength and resistance to corrosion.
Shield: The shield is a protective cover that prevents contamination and debris from entering the bearing, ensuring its smooth operation and longevity.
Connection Structure
To connect the Universal Flange Ball Bearing to a system, follow these steps:
1. Mount the outer ring to a housing or plate: Secure the outer ring to a housing or plate using screws, rivets, or adhesive, ensuring a flat and even surface.
2. Insert the shaft or spindle into the inner ring: Insert the shaft or spindle into the inner ring, ensuring a snug fit and proper alignment.
3. Apply lubrication (optional): Apply a suitable lubricant to the bearing balls and raceways to reduce friction and wear.
4. Secure the inner ring to the shaft or spindle: Use a suitable fastening method (e.g., set screws, snap rings, or adhesive) to secure the inner ring to the shaft or spindle.
5. Verify proper alignment and assembly: Ensure the bearing is properly aligned and assembled to prevent misalignment, vibration, or damage.
By following these steps, you can successfully integrate the Universal Flange Ball Bearing into your IoT device, robotic system, or mechanical assembly, ensuring smooth operation, low friction, and high performance.

    bearingValue = GPIO.input(bearingPin)
    
    # Perform action based on bearing rotation (e.g., send data to cloud)
    if bearingValue == 1:
        print("Bearing rotated, sending data to cloud...")
        # Cloud API call or other action
    else:
        print("Bearing not rotated, standing by...")
