SKF Bearing Cross Reference: SKF and FAG Numbers to ENRO

SKF suffixes and the ENRO code for each

The match is by boundary dimensions only: bore d, outside diameter D and width B. Boundary dimensions follow the ISO 15 dimension series. So the work in an SKF cross reference is translating the suffix. The table lists the SKF codes that appear on 60, 62 and 63 series deep groove ball bearings and what to write on an ENRO order instead.

Two habits trip people up. SKF uses 2Z for shields where most other catalogues write ZZ, and SKF puts clearance after a slash (/C3) where others use a space or a hyphen. Neither changes the size. A number like 6308-2Z/C3 is simply ENRO 6308-ZZ with C3 clearance.

2RSH or 2RS1: which one is on your drawing?

On SKF's current product pages, several sizes that used to be sold as 2RS1 now say the 2RS1 number has been replaced by 2RSH. Other sizes, mostly the larger ones in this range, still list 2RS1. Both are contact seals on both sides, so both translate to ENRO 2RS. The table shows the SKF number that is current for each size; if your records still say 2RS1 for a size where the table says 2RSH, the ENRO number is the same.

FAG numbers with -C, and the older ones without it

FAG's current catalogue lists these sizes as "Generation C", written with -C after the base number: 6205-C for the open bearing, 6205-C-2Z with shields and 6205-C-2HRS with contact seals. Older FAG numbers without the -C, such as 6205-2RSR, are still found on old bearings and in maintenance records, but a search of FAG's current online catalogue returns the -C version instead. We show only the -C numbers. The size has not changed, so an older FAG number maps to the same ENRO row.
