Usually tapered roller bearings.
Bearings are used to let the wheels spin freely and with minimal drag.
Turbochargers turn too fast for ball bearings. Sleeve bearings are typically used in this application.
Yes, rubbing alcohol can be used to clean bearings. It can help dissolve dirt and grime, making it easier to remove them from the bearings. Just make sure to thoroughly dry the bearings after cleaning to prevent any damage from moisture.
Commodity bearings are used in rotating elements that have relatively low revolutions per minute and do not face extreme stresses.
Pivot bearings are frictionless bearings and suitable for pivotal, angular, or oscillating applications. Collar bearings are often used install equipment with a simple set screw.
The Roller bearings can be used at all the places where the severe loading is applied at high velocity between two moving parts
Ball bearings
To reduce unwanted friction.
Brushes and bearings are component parts of a generator. The brushes are used to deliver the field voltage to the revolving rotor. The bearings are needed to allow the rotor to revolve. The bearings also maintain alignment to prevent the rotor from dragging on the stator.
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.
You can't, only tapered roller bearings as used in drums & rotors on some vehicles are adjustable. The rest are just sealed bearings and/or hub & bearing assemblies that are sealed
