Infos Wheelbearings.
Closed bearings are in maintenance more easily, dont need so often or rarely, be cleaned and oiled, are however a little slower.
Therefore open ball bearings are meant for, more for Slotracing but need more maintain and maintenance.
Something faster by small friction resistance and a little less weight.
Hybrid ball bearings, with ceramic(s) balls there should be lighters ?
Now our experience there are expensive, on our laboratory-dares more heavily as our open ABEC of 5 bearings and there dont last long.
Like said our experience with several and with different Brands certainly in the future , then not only the price will be HIGH-Q.
Ball bearings are to be degreased before assembly and be stuck on the chassis, the best is second adhesive(superglue).
Completely important DONT oil to much, the balls love sliding and not Surfen.
Still a few information:
Most good Slotcar ball bearing have, if at all at the most ABEC 3,ABEC classes are brought frequently with the term "quality" in connection.
This is only conditionally correct. It is a "tolerance quality".
ABEC = Annular Bearing Engineers Committee,
AFBMA Norm (An Friction Bearing Manufacturers Assosiation).
The most well-known classes are ABEC 1, ABEC 3, ABEC 5. The more largely the number, the smaller the tolerance values and the more exactly is the camp. In DIN 620 the five tolerance classes PO, P6, P5, P4 and P2 are contained. They agree with the tolerance classes of ISO and ABEC.

Roller and ball bearing steel:Induction vacuum degassing procedure. Fusing temperature 3600°! Electric furnace steels are high-quality, expensive steel. Our ball bearings are manufactured from roller and ball bearing steel 100Cr6 and absolutely rustproof X65Cr13.
Lubricant:
L001 = Öl = Aeroshell Fluid 12
Instrument oil synthetically, using MP continuously -50/+120° C, good aging -, corrosion protection, small evaporation.
We recommend Bluewonder!
With Bluewonder that test ,in the case of the bearing manufacturer, run moment of friction amounts to about 56 to 60 resulted in µNm.
They must be degreased and oiled by the buyer before installation and after-oiled in regular time intervals. Punctual cleaning is preventing maintenance. See to picture internal bearing ring alleged with hybrid, ceramic(s) ball bearing called ABEC 5 |
