FH-1010

F series are drawn cup needle roller bearings without inner ring, featuring a thin-walled outer ring and full-complement needle rollers (without cage). They are designed for high radial load capacity in space-constrained applications, where the shaft surface directly acts as the raceway.FH series are similar to F series but with a flanged outer ring, providing axial positioning while maintaining the inner ring-less design. The flange helps prevent axial displacement, making them suitable for applications requiring both radial load support and simple axial fixation.

Metral：

No cage, allowing more needle rollers for higher radial load capacity.
Reduces radial space requirements.
The shaft surface must have high hardness (typically ≥58 HRC) for optimal performance.
