Decoding the designation

36 — the Fafnir miniature size code for a 6 mm bore in a 19 mm outside diameter, 6 mm wide, which is the ISO 626 envelope.

K — deep groove Conrad construction, which carries radial load and axial load from either direction and has no contact angle.

What these specs mean in practice

A 6 mm bore in a 19 mm outside diameter is the wide-section miniature proportion: the thicker rings and larger balls of the 626 envelope carry noticeably more radial load than the thin 696 section on the same shaft. Closure Type: Open, so the housing or the assembly supplies lubricant directly to the ball path. Internal Clearance: CN, the normal grade, with no clearance code on the designation. Precision Class: Not specified — the designation carries no tolerance suffix.

Quantity and configuration

Unit Quantity: 7 Pcs. Seven single-row bearings ship together.

Interchange guidance

The envelope is the ISO 626 envelope, 6 x 19 x 6 mm, open. SKF 626, FAG 626, NSK 626, NTN 626 and Koyo 626 occupy the same seat. A 696 shares the 6 mm bore in a smaller 15 mm outside diameter and is a related size rather than a substitution. Searchable variants include 36K, 36 K, 36-K, P-36-K and 626.
