HK040806 Bearing

HK040806 drawn-cup needle roller bearing for compact radial support. This is a single open-end needle bearing for assemblies that call for the 4 mm shaft / 8 mm housing / 6 mm width HK040806 or HK0406 size.

Why use this bearing

• Compact radial package: the drawn-cup needle design keeps the outside diameter small while supporting radial load.
• Open-end shell: suitable for through-shaft layouts where the shaft continues past the bearing.
• Right part when the BOM says HK040806/HK0406: use it for the specific needle-bearing pocket, not as a general ball-bearing substitute.

Specifications

• Model: HK040806 / HK0406 size drawn-cup needle roller bearing
• Nominal size: 4 mm bore × 8 mm outside diameter × 6 mm width
• Type: open-end drawn-cup needle roller bearing
• Quantity: 1 bearing

Fitment notes

• Use only where your printed-part pocket, shaft, or project BOM specifies this 4×8×6 mm HK needle-bearing size.
• Not a 608, 625, MR-series, or flanged ball bearing.
• Needle bearings are radial bearings; do not use this as a thrust bearing unless your design separately handles axial load.
