Decoding the designation

9103K — the Fafnir 9100K extra-light spindle deep groove family at 17 mm bore: one row of balls in a deep radial groove, ground to spindle quality on the ISO 6003 envelope.

P6 — Precision Class: ABEC 3 / P6. Tighter bore, outside-diameter and running-accuracy tolerances than standard class.

C1 — Internal Clearance: C1. A radial internal clearance tighter than normal, which reduces radial play and raises running stiffness once the bearing is fitted to an interference shaft seat.

What these specs mean in practice

Dynamic Load Rating: 6,660 N. Static Load Rating: 3,300 N. Lubricant: grease or oil. A deep groove raceway carries radial load and thrust in both directions from a single bearing, so one unit locates a shaft without an opposing partner. ABEC 3 / P6 tolerances with C1 clearance hold shaft position closely, which is what a small spindle, an instrument drive or a precision gearhead is bought for. The extra-light 9100K section puts a 17 mm bore inside a 35 mm outside diameter for a compact housing.

Mounting data

Maximum shaft fillet radius: 0.3 mm. Shaft backing shoulder diameter: 21.5 mm. Housing backing shoulder diameter: 31.1 mm. Outer ring to-clear radius: 0.3 mm.

Quantity and configuration

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