Righto ive got an exo terra that i run on 3s that has an appetite for bearings mainly the 10x15x4 size. I get the 10 for $10 blue rubber sealed ones off flea bay they dont last long. Ceramic bearings are expensive but ill get them if they are more durable. Im also looking at some fast eddy bearings they seem to sit somewhere inbetween ceramic and cheapass. Anyone got any suggestions?
Havnt tried boca and dont get a chance to service bearings before they wear or fail completely. I go out bashing about 4 times a week.does a higher abec number mean a stronger bearing?
The ABEC system explained in reasonable terms (courtesy wikipedia)
The ABEC scale is an industry accepted standard for the tolerances of a ball bearing. It was developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). There are five classes from largest to smallest tolerances: 1, 3, 5, 7, and 9. The higher ABEC classes provide better precision, efficiency,[citation needed] and greater speed capabilities, but do not necessarily make the components spin faster.[1] The ABEC rating does not specify many other critical factors, such as smoothness of the rolling contact surfaces, ball precision or quality/type of steel used.
The bearing material is not specified in the ABEC grades. Bearings not conforming to at least ABEC 1 can not be classified as precision bearings as their tolerances are too loose.
The scale is designed to allow a user to make an informed decision about the type of bearing they are purchasing. High rated bearings are intended for precision applications like aircraft instruments or surgical equipment. Lower grades are intended for the vast majority of applications such as vehicles, mechanical hobbies, skates, skateboards, fishing reels and industrial machinery. High ABEC rated bearings allow optimal performance of critical applications requiring very high RPM and smooth operation. ISO's equivalent standard is ISO 492.[2][3]

class 6X ABEC 3 class 6 ABEC 5 class 5 ABEC 7 class 4 ABEC 9 class 2 Actual changes in run-out between different ABEC grades
There are a number of factors covered by the ABEC grades. One is the eccentricity (roundness) of the track in the inner ring, which determines run-out. The figures given below show the maximum eccentricity allowable.
Cheerz towie reckon i'll get some 5's and see how they go
