Documentation for Radial Ball Bearing 625ZZ for 3D Printer (Pack of 4)
Note: This component is a mechanical part, and as such, it does not have pins. Radial ball bearings are designed to reduce friction and support radial loads in rotating applications, such as 3D printers. They do not require any electrical connections.
However, I will provide a general overview of the bearing's structure and how it is typically used in a 3D printer application.
Structure:
The Radial Ball Bearing 625ZZ consists of an outer ring, an inner ring, and a set of balls that rotate between them.
The bearing has a ZZ (metal shields) on both sides, which protect the bearing from contamination and retain lubricant.
Typical Installation and Connection in a 3D Printer:
The bearing is typically press-fit or mounted onto a shaft or spindle in the 3D printer's moving assembly (e.g., X, Y, or Z axis).
There are no electrical connections to be made to the bearing.
The bearing is designed to provide smooth motion and reduce friction, allowing the moving assembly to operate smoothly and accurately.
Point-by-Point Connection and Installation Guidelines:
Step 1: Inspect the bearing - Before installation, inspect the bearing for any signs of damage or contamination.
Step 2: Prepare the shaft or spindle - Ensure the shaft or spindle is clean, dry, and free of debris.
Step 3: Press-fit or mount the bearing - Press-fit the bearing onto the shaft or spindle, or mount it using the recommended method (e.g., set screws, snap rings, or bearings mounts).
Step 4: Secure the bearing - Ensure the bearing is properly secured to the shaft or spindle using the recommended method (e.g., set screws, snap rings, or bearings mounts).
Step 5: Lubricate the bearing (optional) - Apply a small amount of lubricant to the bearing if recommended by the manufacturer.
Step 6: Assemble the 3D printer - Reassemble the 3D printer's moving assembly, ensuring proper alignment and clearance.
Important Notes:
Handle the bearing with care to avoid damage or contamination.
Follow proper installation and maintenance procedures to ensure the bearing operates smoothly and extends its lifespan.
Refer to the manufacturer's documentation and the 3D printer's user manual for specific installation and maintenance instructions.

Usage Examples
-----------------

### Example 1: Replacing X-Axis Bearings in a Prusa i3 3D Printer

In this example, we'll demonstrate how to replace the X-axis bearings in a Prusa i3 3D printer using the Radial Ball Bearing 625ZZ.

Hardware Required:

Radial Ball Bearing 625ZZ (pack of 4)
 Prusa i3 3D printer
 X-axis rod
 X-axis motor mount

Step-by-Step Instructions:

1. Disassemble the X-axis assembly by removing the motor mount and belt pulley.
2. Remove the old bearings from the X-axis rod.
3. Clean the rod and apply a thin layer of lubricant.
4. Install the new Radial Ball Bearing 625ZZ onto the X-axis rod, ensuring proper alignment and seating.
5. Reassemble the X-axis assembly.

Code Example (Marlin Firmware):
```c
// X-axis configuration
#define X_AXIS_BEARING_TYPE 625ZZ
#define X_AXIS_BEARING_COUNT 4

// X-axis motor configuration
#define X_AXIS_MOTOR_TYPE Stepper
#define X_AXIS_MOTOR_STEPS 200

// X-axis homing configuration
#define X_AXIS_HOME_DIR -1
#define X_AXIS_HOME_SPEED 1200
```
### Example 2: Using the Radial Ball Bearing 625ZZ in a Custom 3D Printer Design

In this example, we'll demonstrate how to integrate the Radial Ball Bearing 625ZZ into a custom 3D printer design using a CNC-machined aluminum axis assembly.

Hardware Required:

Radial Ball Bearing 625ZZ (pack of 4)
 CNC-machined aluminum axis assembly
 Stepper motor
 Motor controller
 3D printer mainboard

Step-by-Step Instructions:

1. Design and CNC-machine the aluminum axis assembly to accommodate the Radial Ball Bearing 625ZZ.
2. Install the bearings onto the axis assembly, ensuring proper alignment and seating.
3. Connect the stepper motor to the motor controller and 3D printer mainboard.
4. Write the firmware configuration to control the X-axis motor and bearings.

Code Example (Arduino Firmware):
```c
#include <Stepper.h>

// Stepper motor configuration
const int x_axis_motor_pins[] = {2, 3, 4, 5};
Stepper x_axis_motor(x_axis_motor_pins, 200);

void setup() {
  // Initialize the X-axis motor
  x_axis_motor.setSpeed(1200);
}

void loop() {
  // Move the X-axis to a specific position
  x_axis_motor.moveTo(100);
  delay(1000);
}
```
Important Notes
-----------------

Always handle the bearings with care to prevent damage or contamination.
 Ensure proper lubrication and maintenance to prolong the lifespan of the bearings.
 Consult the 3D printer's documentation and/or manufacturer support for specific installation and configuration instructions.
