Lidt dyrere, men det afhænger af størrelserne. Men de er af kendt kvalitet (Koyo), hvorimod tHansens er (var?) noname. Iøvrigt har Max alle de størrelser man normalt bruger på MC. Og hvis størrelsen ikke er på lager, skaffer pusheren SKF lokalt. (Til lavere pris end jeg giver som privat-kunde hos hans leverandør...#¤%#!!)
Forresten, fra SKF's elektroniske katalog:
Særligt Cx skal man være opmærksom på.

The designation suffixes used to identify certain features of SKF deep groove ball bearings are explained in the following.
CN Normal radial clearance; generally only used in combination with one of the following letters which indicate reduced or displaced clearance range
F reduced and displaced clearance range covering the upper most quarter of the actual clearance range plus the lowest quarter of the next greater clearance range
H reduced clearance range corresponding to the upper half of the actual clearance range
L reduced clearance range corresponding to the lower half of the actual clearance range
P displaced clearance range corresponding to the upper half of the actual clearance range plus the lower half of the next greater clearance range
The above letters are also used together with the following clearance classes: C2, C3, C4 and C5
C2 Radial internal clearance less than Normal
C3 Radial internal clearance greater than Normal
C4 Radial internal clearance greater than C3
C5 Radial internal clearance greater than C4
DB Two single row deep groove ball bearings matched for paired mounting in a back-to-back arrangement.The following letter combinations follow immediately after the DB and indicate the magnitude of the internal clearance or preload of the matched pair before mounting:
CA small axial clearance
GA slight preload
DF Two single row deep groove ball bearings matched for paired mounting in a face-to-face arrangement. The following letter combinations follow immediately after the DF and indicate the magnitude of the internal clearance or preload of the matched pair before mounting:
CA small axial clearance
GA slight preload
DT Two single row deep groove ball bearings matched for paired mounting in a tandem arrangement
