Ball, roller, and needle bearings are made of various hard steel alloys.
Bushings are coated with either a soft alloy called Babbitt metal or a plastic over the contact surface. This coating slowly wears away, protecting the shaft and journal from direct contact.

The type of bearing that would be fitted to a fractional kW electric motor will depend on the model and maker of the motor. Deep grove ball bearings are the most common bearings used.
If installed correctly then yes you can on most systems. This depends on the spacing of your purlins, the type of metal used, the panel style used, the thickness of metal used, and the slope of the roof.
Thrust bearings are a type of rotary bearing designed to support a high axial load while allowing movement between two parts. There are many types of thrust bearings, but they are typically used for automotive assemblies, particularly in wheel hubs and manual transmissions.
Think of bushings as they really are: a consumable bearing. They don't move and are not as hard as bearings. They are composite material usually containing a lot of brass. They are present in the engine and the transmission.
Babbitt metal is a common soft metal alloy made of tin, copper, and antimony, used to line bearings and reduce friction. It is known for its ability to withstand moderate loads and provide a low coefficient of friction. Other types of soft metal alloys used for this purpose include lead-based materials like lead-tin and lead-bronze alloys.
Bushings are used as bearings to reduce friction and wear between moving parts in machinery and vehicles. They provide a smooth surface for shafts or bolts to rotate or slide against, helping to maintain proper alignment and stability. Additionally, bushings can absorb shock and vibration, extending the lifespan of components and improving overall performance. They are commonly made from materials like rubber, plastic, or metal, depending on the application requirements.

There are mainly two types of bicycle bearings: ball bearings and cartridge bearings. Ball bearings use small metal balls to reduce friction, while cartridge bearings are self-contained units that are easier to replace. The type of bearings used can affect the smoothness of the bike's movement and overall performance, as well as the ease of maintenance and durability.

There was no hammer used to crucify Jesus. The Romans used a whip with bone and metal bearings, though.
