Decoding the designation

9111 — Fafnir 9100K spindle deep groove dimension series, bore code 11: 55 mm bore, 90 mm outside diameter, 18 mm width. That is the ISO 6011 envelope.

N — snap ring groove machined into the outside diameter of the outer ring, so the bearing can be located axially in a through-bored housing.

PP — two land-riding contact rubber seals, one on each face, retaining the factory grease charge.

What these specs mean in practice

The 9100K series is Fafnir’s spindle deep groove line: the same Conrad geometry as an ordinary 6011, ground and gauged to spindle standards for running accuracy and quiet running. A deep groove bearing takes radial load and axial load in either direction, which is what lets one bearing locate a shaft in both directions where an angular contact bearing needs a partner.

The snap ring groove saves a housing shoulder. In a through-bored housing the retaining ring does the axial location that a machined step would otherwise have to provide, which shortens the housing and simplifies the bore.

Quantity and configuration

Unit Quantity: 1 Pc. One complete sealed bearing, inner ring, outer ring, ball complement, cage and both seals.

Interchange guidance

Cross-Reference: 6011-P6, as marked. Searchable variants of the Fafnir number: PAMG9111NPP2, PAMG-9111-NPP2, PAMG 9111 NPP2, 9111NPP2, 9111NPP.

The 55 x 90 x 18 mm envelope is the ISO 6011 seat, so a 6011 of matching closure and precision occupies the same housing bore and shaft.
