Tapered roller bearings.
Chevy has a floating axle, the bearings share grease in common with the differential. By filling the diff you are greasing the wheel bearings. Onjig
They are the parts of the hub which touch the stub axle. They are made a friction-free as possible and in modern cars are roller bearings or ball bearings.
they are oil bath, they get oil from the differential
A semi-floater axle is one that all the vehicals weight and rotational torque are placed on the outside bearing and axle. A full-floater axle has a separate bearing assembly on the end of the axle housing to support the weight of the vehical and rotational torque is the only load on the axle shaft. A full floating axle is easy to spot because the bearings protrude through the center of the wheel.

Answer:Outdoor wheels are more rubbery and grippy and indoors are hard plastic
Bearing assemblies, such as ball bearings or roller bearings, are commonly used between a wheel and an axle to reduce friction. These components facilitate smooth rotation by allowing the wheel to turn with minimal resistance against the axle, thus improving overall efficiency and performance.
It depends on the model. Older models have bearings of an outer diameter bigger than regular skateboard wheels, and the axle is larger than the inner diameter of standard bearings. Newer models may have switched to a standard bearing. Skateboard shops sometimes have the proper sizes for older models, but roller skate wheels are closer. However the bearings do not fit standard wheels for skateboards or roller skates. If you have a good shop they can arrange to have the wheels ground out to accommodate the larger bearing, or you can have the axle machined to a smaller diameter and switch to standard bearings.
Axle bearings support the weight of the vehicle and are called several different things depending on the suspension, axle, and control systems attached.
In a full-floating axle, the axle bearing is placed on the outside of the axle housing. This places all the vehicle weight on the axle housing and none on the axle itself. This is important for the front axle which is generally a short shaft. In the semi-floating axle, the axle bearing is placed in the axle housing and the axle carries some of the load of the vehicle. The main advantage of the semi-floating is that it is simpler (i.e. cheaper). Courtesey of: http://www.m38a1.ca/axles.html Sourced by: Paul Henderson, Donegal, Ireland.
Wheel bearings, main bearings, connecting rod bearings, cam bearings, axle bearings, carrier bearings, pinion bearings and so on, need to be more specific.
