A few types of bearings are plain bearings, jewel bearings, and fluid bearings.
FKD bearings
Bearings are separate devices into machines and also ones that can be used in pulleys for friction. There are different types and sizes. INA bearings are a division of the Schaeffler Group and make rolling and plain bearings which are designed for rotary motion.
Rear end differentials have several different types and sizes of bearings. The cost to replace all of the bearings will be around $400.
ball type
INA Bearings make a wide range of ball bearings and their inserts. These are used in a wide range of products, though they are best known for their use in skateboards.
there are many types of bearings .... 1)ball bearing 2)roller bearing 3)ball thrust bearing 4)roller thrust bearing & 5)tapered roller thrust..
Ball bearings are a rolling device that helps reduce friction with rolling apparatus with a ball and enables smooth movement. There are basically two types of ball bearings; radial and thrust. A radial is a pulley that is handles by tension, while a thrust type puts stress on the bearing to put weight on the load.
When you take the old bearings out they should have a number on them, write that number down and take it to a skate shop, or store that sells bearings. or just take your trucks or the whole board to a skate shop they will help you out.

Wheel bearings, main bearings, connecting rod bearings, cam bearings, axle bearings, carrier bearings, pinion bearings and so on, need to be more specific.
The bearings on the end of piston rods, connecting them to the crankshaft are 'thrust' bearings, on some cars the end of the crankshaft, where it comes out of the front that the harmonic balancer aka crank pulley is on use a ball bearing. Components driven by the serpentine belt, or in older cars V-belts, like the alternator use sealed roller or ball bearings
There is a website called Bearings Direct where it has a selection of different types of roller bearings for an affordable price. You will need to register for an account first before making any purchases.
