i think its either iron or steal
If you need replacements, they can be bought at a hardware store. If you mean applications/uses ... bicycle wheels have ball bearings. Lots of rolling objects that move around an axle have either needle bearings or ball bearings or roller bearings.
Ball bearings are typically made of steel, which is not a magnetic material. They will sink in water and not float because their density is higher than that of water. If exposed to a strong magnetic field, ball bearings made of magnetic materials like iron may be attracted to the magnet.
No, ball bearings are small metal balls placed inside a ring to reduce friction in rotating machinery, while wheel bearing hubs are components that house the bearings and attach the wheel to the vehicle's axle. Wheel bearing hubs contain ball bearings as part of their mechanism.
Rolling friction occurs when moving parts have ball bearings. This type of friction is lower than sliding friction, as the ball bearings allow the parts to roll smoothly over each other with less resistance.
To reduce friction, you can use lubricants such as oil or grease, polish the surfaces to make them smoother, use ball bearings or rollers, or introduce a layer of Teflon or other low-friction material between the surfaces in contact.
Turbochargers turn too fast for ball bearings. Sleeve bearings are typically used in this application.
Why funnel is used for dropping the ball bearing
Ball bearings
ball type
Ceramic ball bearings are used for reducing frictional rotation, and to support radial and axial loads. It helps any application looking to have higher RPM.
Ball & Roller Bearings both belongs to the category of radial contact bearings.In case of ball bearings spherical balls are used however in case of roller bearings cylindrical rollers are used.due to balls used in ball bearings there is a point contact is made whether it is line contact in roller.
The standard size range for ball bearings used in industrial machinery typically falls between 1mm to 200mm in diameter.

Faulty ball bearings lead to bearing failure.
Generally, a ball bearing is used when speed is important; a roller bearing is used more often when load is most important.
Ball bearings are polished by using an abrasive cloth. Before the bearings can be polished, the polishing paste must first be applied to the ball bearing.
