SF68 Series SUS440 Stainless Steel Flanged Bearings

The F68 series consists of ultra-thin-walled miniature flanged bearings. Manufactured from SUS440 stainless steel, these bearings combine high hardness with excellent corrosion resistance. Their extremely small cross-section makes them ideal for precision machinery where space constraints are critical.
The key advantage of the F68 series lies in its ultra-thin design, which significantly reduces radial space requirements while maintaining necessary structural strength.

Bearing Features

The integrated flange on the outer ring simplifies axial positioning; during precision assembly, this feature effectively prevents axial displacement within the housing bore, streamlines housing machining processes, and enhances overall assembly efficiency and stability. Constructed from high-carbon chromium stainless steel, the bearings maintain superior geometric precision and wear resistance even during high-speed operation, thereby extending maintenance intervals for equipment subjected to frequent use.
