Product Description

What this part is:

Fafnir 2MM9105WICRDUL is a super-precision angular contact ball bearing supplied as a universally ground duplex pair, two bearings. Each bearing measures 25 x 47 x 12 mm with a 15° contact angle, a phenolic cage and light preload (DUL).

Decoding the designation:

2MM — Fafnir super-precision spindle range at a 15° contact angle, P4 precision (ABEC 7).

9105 — the 9100 light dimension series, bore code 05, which maps to the ISO 7005 size: 25 mm bore, 47 mm outside diameter, 12 mm width.

WI — low shoulder on both rings.

CR — phenolic cage.

DUL — duplex pair, universally ground, light preload. Either face can be brought together, so the pair mounts back-to-back, face-to-face or in tandem.
