What this part is: Fafnir M9111K single-row spindle deep groove ball bearing, 9100K series, made in the USA. Bore Diameter: 55 mm. Outside Diameter: 90 mm. Overall Width: 18 mm. Bore Type: Straight. Closure Type: Open. Rolling Elements: Ball. Number Of Rows: 1. Bearing Material: Chrome steel. Internal Clearance: CN. Precision Class: ABEC 3 / P6. Series: 9100K. Base Number: 9111K. Decoding the designation: 9111 — 9100 light series, bore code 11, giving a 55 mm bore on the 90 mm outside diameter of the 6011 envelope. K — spindle deep groove execution: a Conrad-type deep groove raceway built to spindle tolerances, so it carries no contact angle. What these specs mean in practice: Dynamic Load Rating: 31,400 N at one million revolutions, and 28,500 N on the ISO basis. Static Load Rating: 21,400 N. Precision Class: ABEC 3 / P6, a tighter running and dimensional tolerance than a standard commercial deep groove bearing. Internal Clearance: CN, the standard clearance group. The 9100 light series puts a thinner section on a given bore, which keeps the bearing compact where the housing bore is limited, and the deep groove raceway still takes axial load from either direction alongside the radial load. Mounting data: Maximum shaft fillet radius cleared by the bearing corner: 1 mm. Shaft backing shoulder diameter: 62.2 mm. Housing backing shoulder diameter: 83.3 mm. Outer ring “to clear” radius: 1 mm. Lubricant: grease or oil. Quantity and configuration: Unit Quantity: 1 Pc. Single bearing, open on both faces. Interchange guidance: The envelope is the standard 6011 boundary at 55 x 90 x 18 mm, so a standard-class 6011 from SKF, FAG, NSK, NTN, Koyo, MRC or Nachi fits the same seat. Those are commercial Conrad-type bearings at normal tolerance; this piece is the spindle execution at ABEC 3, and the Timken MM9111K is the same size at P4S. Searchable forms of the number: M9111K, M-9111-K, M 9111 K, 9111K, MM9111K and 6011.
