Steel ball bearings are the most common type of bearings due to their strength and precision. Precision is essential when it comes to ball bearings. Steel can be manufactured to precise measurements, providing a high-precision ball bearing.
Steel is a tough metal which can be used in challenging environments. Ball bearings are often used in demanding applications which require high speeds and heavy loads. Using a steel ball bearing can ensure durability and prevent machine downtime. Steel and stainless steel is also corrosion resistant. Meaning the metal can withstand deterioration from wear and tear. It is are resistant to chemical breakdown. This is ideal for environments which may use chemicals or have moisture.
The downsides of a steel bearing are that they can be heavy and often require lubrication for optimal performance.
There are several parts of a ball bearing which can be made from steel or other materials.
