1. Ball Bearings
Ball bearing types
Loose the balls can be removed individually (and roll away forever)
1-piece the balls are in a retainer ring than cannot be removed
1-piece the contact is radial in a full-U shape “full contact”
1-piece for carrying pure-radial loads (perpendicular to the axle)
3-piece the balls are in a retainer ring that can be removed
3-piece the contact is angular in a half-U shape, for some side loads
3-piece only Bo15, L17 and E20 are 3-piece “angular contact”
1-piece versions
00 open: has no shields or seals
RS sealed: has a rubber seal on one side
2RS double sealed: has rubber seals on both sides
Z shielded: has a shield on one side
ZZ double shielded: has shields on both sides
The shields or seals are pressed in. They can be removed by poking a small hole with something like a dental pick, and then prying the hole outward.

Note 1: This is on 1984-later Puch E50 engines, with crankshaft 349.310.1150 (not 349.110.1150). It has the same dimensions 17 x 40 x 12, but the inner race on the side opposite the outer clip groove is recessed by 1 mm to 11. It is also for the Top Racing crank, and other late-80’s compatibles.

Roller bearings can carry more weight, but are for low rpm. Thin long rollers are called “needle”.
Ball bearings can take higher rpms and have less friction than rollers.
Rollers can be horizontal (radial loads), angled (radial and side loads), or vertical (side loads).
All of these below have horizontal rollers for pure radial loads.

The benefits of a needle bearing compared to a bushing are 1) ability to operate with low lubrication, 2) less friction and therefore less heat generated, 3) floating needles can fit a small range of diameters, as long as OD minus ID equals twice the roller diameter.

One side has writing and an anti-clockwise arrow. The other side is plain.
Viewed from the writing end, the shaft can only rotate anti-clockwise. Clockwise it locks solid.
Installed in a Tomos clutch drum, the writing side faces out.
When a Tomos piston seizes, this can get damaged, and become locked in both directions.
6. Bushings
Spacers and bushings are metal or plastic tubes, that can have the same appearance. The name depends on what the tube does. A “spacer” carries an axial load, where the length matters the most. A “bushing” carries a radial load, where the diameter matters the most. Bushings are also called “plain bearings”. Spacers are also called “distance bushings”. This source of confusion is similar to that of “mopeds” and “scooters”.

Clacking vs Clattering
Precision Reaming
Most of these require reaming after they are pressed into the rod. The reasons are 1) they have a very tight press fit for their size, so much that the inside diameter becomes smaller after they are pressed in, and 2) some are made slightly larger or smaller than others. Only Puch and Jawa offered pre-reamed piston pin bushings, which can sometimes need light reaming. The reason why not every kind is made pre-reamed, is that pre-reamed or re-used ones do not hold as tight as un-reamed new ones. When they don’t hold tight they can slip easier.
Disaster strikes: Piston bushing slippage causes oil hole blockage. Then the piston pin and bushing do not get any lubrication. Not having oil mixed with the gasoline also causes the piston bushing to not get any lubrication. Without oil, soon the bushing overheats and sticks-melts to the piston pin. That causes the piston pin to rotate back and forth inside the piston, instead of being stationary. After a while the piston pin holes wear out. The loose piston begins to make a clacking sound at idle and a screeching sound at high speed. The compression ratio is reduced by the loose piston. That causes the engine to be less powerful and difficult to start. The incomplete combustion also makes the spark plug black, which worsens the tendency to be difficult or impossible to start.
