Wear Sleeves (cont.)
8. Drop the Speedi-Sleeve into the end of the installation tool so
only the flange end projects (fig. 6f). The flange end of the sleeve goes
on the shaft first. Gently tap the center of the tool using a soft face
hammer or mallet until the sleeve reaches the previously marked
or pre-measured point on the shaft (fig. 6g).
…then gently tap center of tool
using soft-face hammer or
mallet until sleeve reaches
desired point on shaft (fig. 6g).
When Speedi-Sleeve is in position,
flange can be removed (fig. 6h).

9. Speedi-Sleeves may be installed to any depth required (refer to SKF
Handbook of Seals). If the installation tool supplied with sleeve is too
short, a length of pipe with a squared-off, burr-free end can be
substituted if its I.D. matches the kit installation tool.
10. Inside pipe diameters should be larger than the shaft by:
Shafts less than 3” (75mm): 1/32” to 1/8” (.8mm to 3.2mm)
Shafts 3” to 6” (75-150mm): 1/32” to 3/16” (.9mm to 4.8mm)
Shafts more than 6”: (150mm) 3/64” to 7/32” (1.2mm to 5.6)
The installation tool correctly places the sleeve on the shaft to the
required installation depth (intermediate values can also be obtained by
pressing the sleeve on more or less as required).
11. If clearance is needed, the Speedi-Sleeve flange can be removed
easily with side cutters and carefully pried away from the sleeve. Bend
flange back and forth until flange cracks at tear groove. The flange will
peel away from sleeve surface along a precut line (fig. 6h). Be careful
nothing scratches the sleeve surface.
Large Diameter Wear Sleeves
Large diameter wear sleeves correct damaged shafts from 8” to 45”
(203.20 - 1143.00mm) (fig. 6i). Though they function the same as
SKF Speedi-Sleeves, these sleeves are designed and built for heavyduty,
large shaft applications. Installed over a seal grooved shaft, the
sleeve provides a positive sealing surface and reinforced protection.
They are available with or without an installation flange. They also
resist wear and corrosion, especially in contaminated environments.
SKF large diameter wear sleeves are custom-made from high quality
cold-rolled steel, SAE 1005-1020. The sealing surface is machined
and hard chrome-plated to provide a strong, corrosion-resistant
sealing surface. The standard thickness of the sleeve is 0.094”
(2.4mm). Other materials and thicknesses are available on a
quote basis.
