Heavy Duty 1/2 Inch Flanged Ball Bearing W/ Integrated 3/16 Pin And 3/8 Long Axle Pin Perfect For DIY Projects And Smooth Rotational Moves

1/2 Inch (12.70mm) Flanged Ball Bearing With 4.76 Pin
✔️ 1/2 inch OD 4.76 PIN 3/8 AXLE LENGTH STEEL BEARING PACK

This unit serves as a compact rotary support for axles measuring 4.76mm 3/16 inch across many hobby setups. The sealed ball bearing design allows smooth rolling motion while keeping out dirt particles easily in workshop environments when installed correctly. Commonly used when precise shaft guidance is needed within tight mechanical assemblies for reliable performance.

✅ Outer diameter measures 0.5 inch 12.70mm for round shape
✅ Overall span runs 3/8 inch 9.53mm to fit narrow slots
✅ Pin size is 3/16 inch 4.76mm for standard axle mounting
✅ Material built tough using 52100 chrome steel components

💡 Why pick steel ball bearings over plastic options for axles? Heavy duty parts rely on durable metals to withstand constant friction and heavy loads better than synthetic alternatives that wear down fast during use.
- High carbon content creates hardness to resist surface deformation
- Better heat distribution reduces risk of seizing in heated motors
- Reliable performance ensures consistent rotation speed for projects
