Shaft Sleeve 99118 for 30.1-30.23 mm Shafts

The SKF 99118 wear sleeve fits shafts measuring 30.1 mm to 30.23 mm in diameter. It is designed for heavy industrial applications where a damaged shaft surface needs repair. The chromium-plated stainless steel construction resists wear up to 225 degrees F. This sleeve restores the sealing surface without replacing the shaft.

Critical Shaft Diameter Range 30.1 to 30.23 mm

The sleeve only fits shafts within the 30.1 mm minimum and 30.23 mm maximum diameter range. An outside diameter tolerance of 1.6 mm and width tolerance of 0.8 mm define the manufacturing limits. Verifying the shaft size against these exact figures is the single step that decides if this part will work.

Chromium-Plated Stainless Steel Extends Seal Life

The 0.28 mm wall thickness adds minimal radial bulk while the chromium-plated finish provides a hard, smooth counterface for rotary seals. The 7.95 mm width on shaft and 11.13 mm overall width position the sealing surface precisely. The 35.56 mm flange diameter locates the sleeve axially during installation.

Questions about this item

What shaft sizes does the 1.185-1.190 in sleeve actually cover?

It fits shafts from 30.1 mm up to 30.23 mm, matching the 1.185 in to 1.190 in range.

How does the 35.56 mm flange diameter limit the housing bore?

The flange measures 35.56 mm across, so the housing bore must be large enough to clear that diameter.

What clearance is needed to slide the 11.13 mm wide sleeve into place?

The overall width is 11.13 mm, with 7.95 mm sitting on the shaft; allow at least that much axial space.
