Product Description

What this part is

Fafnir PM9103K spindle deep groove ball bearing. Bore Diameter: 17 mm. Outside Diameter: 35 mm. Overall Width: 10 mm. Series: 9100K. Base Number: 9103K. Number Of Rows: 1. Rolling Elements: Ball. Bore Type: Straight.

Decoding the designation

9100K — Fafnir spindle deep groove series, the precision-ground counterpart to the ISO 6000 light series.

9103 — the 17 mm bore size within that series, matching the ISO 6003 envelope of 17 x 35 x 10 mm.

P6 — Precision Class: ABEC 3 / P6, the tolerance grade carried on the carton alongside the 6003 cross-reference.

What these specs mean in practice

Dynamic Load Rating: 6,660 N. Static Load Rating: 3,300 N. The deep groove raceway carries radial load and axial load from either direction, which is what separates this construction from an angular contact execution.

Limiting Speed: 39,600 rpm grease; 79,200 rpm oil. Bearing Material: Steel. Internal Clearance: CN. ABEC 3 tolerances hold the bore, outside diameter and running accuracy tighter than a standard-class bearing, giving closer shaft location and lower running vibration in a spindle.

Mounting data

Shaft backing shoulder diameter 21.5 mm. Housing backing shoulder diameter 31.1 mm. Maximum housing fillet radius 0.3 mm. The straight bore mounts directly on a ground shaft journal.

Quantity and configuration

Unit Quantity: 14 Pcs. Fourteen single-row bearings ship as one lot.

Interchange guidance

The 17 x 35 x 10 mm envelope at P6 tolerance is the ISO 6003-P6 size, so a P6-class 6003 from any major maker drops into the same seat. The Fafnir MM9103K is the same envelope built to ABEC 7/9 and is listed here as a related higher-precision execution rather than a like-for-like swap.
