the big end bearings torque down at 55 - 65 Nm
If you are referring to an internal combustion engine they are also called the 'big ends'. These are the bearings on the crankshaft and connecting rods, the bearings on the other end of the connecting rods are the 'small ends'.
Ball bearings come in a wide range of sizes from really tiny to really big. That less-than-specific answer reflects the less-than-specific question. There are a variety of ball bearings out there, and you can always specify a custom size if you can't find one off the shelf that suits you.
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
Problems with main bearings normally show up as a rumble. Big end bearings rattle.
Faulty ball bearings lead to bearing failure.
Ball bearings are polished by using an abrasive cloth. Before the bearings can be polished, the polishing paste must first be applied to the ball bearing.
If you need replacements, they can be bought at a hardware store. If you mean applications/uses ... bicycle wheels have ball bearings. Lots of rolling objects that move around an axle have either needle bearings or ball bearings or roller bearings.
SIC 3562 applies to BALL AND ROLLER BEARINGS.
Torque settings for main bearings and big end bearings
Turbochargers turn too fast for ball bearings. Sleeve bearings are typically used in this application.
