Hitachi 319-693 Spare Part - Needle Bearing (d22)

Genuine Hitachi needle bearing — part number 319693 (Needle Bearing D22) — designed to replace the worn bearing that supports the cam shaft in Hitachi portable rebar cutter/bender models like the VB16Y.

This D22 designation refers to a 22 mm bearing diameter; the service manual shows the bearing seated on the cam shaft and removed during gear-cover disassembly, so it restores smooth rotation and corrects play in the cam/gear area.

Fits Hitachi VB16Y (and related VB3616DAM/VB3616 series) applications where that needle bearing is listed in the parts diagram — a direct-match replacement made to original Hitachi specification.

Quick details:

- Part: Needle Bearing D22, Hitachi 319693.

- Diameter: 22 mm (D22).

- Function: supports cam shaft / gear assembly for smooth cutting and bending action.

This genuine Hitachi part is a simple swap-in when the bearing shows wear or noise — keeping the rest of the mechanism aligned and reducing further gearbox wear — and is one of the common power tool parts you’ll want when servicing a VB16Y-series rebar cutter.
