99315 SKF Speedi-Sleeve 80.01x89.99x24 mm - Shaft Repair Sleeve

99315 SKF Speedi-Sleeve 80.01x89.99x24 mm - Shaft Repair Sleeve

SKF 99315 is a standard SKF Speedi-Sleeve designed to restore the sealing surface of a worn or damaged shaft without machining or replacing the shaft. It is intended for shafts measuring 79.91-80.09 mm. The sleeve has a nominal diameter of 80.01 mm, flange diameter of 89.99 mm, seal seat width of 21.01 mm and total width of 24.00 mm.

SKF 99315 Speedi-Sleeve - characteristics

SKF Speedi-Sleeve is a thin-walled shaft repair sleeve developed specifically to provide a new counterface for a radial shaft seal.

When a shaft develops a groove, scoring or wear in the area contacted by the sealing lip, replacing the shaft or machining its surface can be expensive and time-consuming. SKF 99315 provides a new sealing surface directly over the existing shaft.

The original seal size can normally be retained because of the very thin sleeve wall.

Technical data

The dimensional values above correspond to the SKF Speedi-Sleeve catalogue data for designation 99315.

What does SKF 99315 mean?

SKF identifies the manufacturer.

99315 is the specific SKF Speedi-Sleeve designation.

Unlike a rolling bearing designation, 99315 does not encode a conventional bearing series, bore diameter, clearance or sealing suffix. It is a product reference identifying a specific size of SKF Speedi-Sleeve.

The most important selection parameter is the actual measured shaft diameter. SKF 99315 is intended for shaft diameters from 79.91 mm to 80.09 mm.

What is SKF Speedi-Sleeve?

SKF Speedi-Sleeve is a precision thin-walled sleeve installed over a worn shaft surface.

A radial shaft seal operates with its sealing lip in continuous contact with the shaft counterface. Over time, this contact can produce a wear track or groove. Corrosion, contamination or mechanical damage can also deteriorate the sealing surface.

Installing SKF 99315 over the affected area creates a new counterface for the sealing lip.

This can eliminate the need for operations such as:

• shaft replacement

• machining the worn surface

• grinding the shaft

• hardening and refinishing the sealing area

• changing to a different seal size solely because of shaft wear

Shaft diameter range 79.91-80.09 mm

The shaft diameter range is one of the most important parameters when selecting an SKF Speedi-Sleeve.

SKF specifies 99315 for a shaft diameter range of:

79.91-80.09 mm

The nominal sleeve diameter is:

80.01 mm

The shaft should therefore be measured accurately before ordering the sleeve. Selection should be based on the actual diameter of the shaft rather than solely on the machine type or the nominal dimensions stated in general documentation.

Dimensions of SKF 99315

SKF catalogue dimensions for 99315 are:

• shaft diameter range: 79.91-80.09 mm

• nominal sleeve diameter d1: 80.01 mm

• flange diameter D: 89.99 mm

• seal seat width b1: 21.01 mm

• total width b: 24.00 mm

• maximum installation distance B: 34.93 mm

The values 21.01 mm and 24.00 mm should not be confused. They describe different dimensional characteristics of the sleeve.

Standard SKF Speedi-Sleeve

SKF 99315 is listed as a Standard Speedi-Sleeve.

This distinction is important because SKF also offers Speedi-Sleeve Gold versions for selected dimensions. A Gold version should not automatically be treated as identical to the standard 99315 solely because the shaft diameter is similar.

The complete SKF designation and dimensional specification should always be checked.

How does SKF 99315 work?

The sleeve is positioned over the damaged or worn section of the shaft where the radial shaft seal lip operates.

After installation, the sealing lip runs on the surface of the Speedi-Sleeve rather than directly on the previously worn shaft.

The repair therefore focuses specifically on restoring the seal counterface.

The solution is particularly useful where the shaft remains mechanically serviceable but its sealing surface is no longer suitable for reliable operation with a radial shaft seal.

SKF 99315 vs shaft machining

Traditional repair of a worn sealing surface can require shaft removal and subsequent machining or refinishing.

SKF Speedi-Sleeve provides an alternative approach. The sleeve creates a new sealing surface over the existing shaft.

An important practical advantage is that the original radial shaft seal size can generally be retained. The repair therefore does not automatically require a seal with a different inside diameter.

Selecting SKF 99315

Before ordering SKF 99315, check:

1. Actual shaft diameter.

2. Diameter at several points around the sealing area.

3. Condition of the shaft surface.

4. Location of the existing wear groove.

5. Width of the sealing area.

6. Position of the seal lip after installation.

7. Available installation space.

8. Complete SKF designation.

For SKF 99315, the measured shaft diameter must correspond to the specified 79.91-80.09 mm range.

A sleeve should not be selected solely because the shaft is described nominally as 80 mm.

Alternative designations and search references

SKF 99315 may naturally be searched or identified as:

• SKF 99315

• 99315 SKF

• SKF Speedi-Sleeve 99315

• 99315 Speedi-Sleeve

• SKF 99315 Speedi Sleeve

• SKF 99315 shaft repair sleeve

• SKF repair sleeve 99315

• SKF Speedi-Sleeve 80 mm

• SKF 99315 80 mm

The correct manufacturer designation remains 99315.

Installation

Before installing SKF 99315, the shaft surface should be cleaned and inspected carefully.

Burrs, raised damage and contamination should not remain underneath the sleeve. The shaft diameter should also be measured accurately before installation.

The sleeve should be installed evenly using the appropriate installation method and tool. Excessive impact or uneven force can damage or deform the thin sleeve.

The position of the sleeve should ensure that the radial shaft seal lip operates entirely on the repaired surface.

SKF installation instructions should be followed for the specific repair.

FAQ

What is SKF 99315?

SKF 99315 is an SKF Speedi-Sleeve shaft repair sleeve. It provides a new running surface for a radial shaft seal on a worn or damaged shaft.

What shaft diameter is SKF 99315 designed for?

SKF specifies a shaft diameter range of 79.91-80.09 mm for Speedi-Sleeve 99315.

Is SKF 99315 suitable for an 80 mm shaft?

It is designed around a nominal 80 mm shaft size, but the actual shaft must be measured. SKF specifies an acceptable shaft diameter range of 79.91-80.09 mm.

What is the diameter of SKF 99315?

The nominal sleeve diameter d1 is 80.01 mm. The flange diameter D is 89.99 mm.

What is the width of SKF 99315?

The seal seat width b1 is 21.01 mm and the total sleeve width b is 24.00 mm. These are separate dimensions and should not be confused.

Does SKF 99315 replace the oil seal?

No. SKF 99315 repairs the shaft surface on which the radial shaft seal operates. It does not replace the radial shaft seal itself.

Do I need a larger oil seal after installing SKF 99315?

Normally, SKF Speedi-Sleeve allows the original seal size to be retained. The sleeve is specifically designed as a thin-walled repair solution for the existing shaft and seal arrangement.

How should SKF 99315 be selected?

Selection should be based primarily on an accurate measurement of the shaft. For 99315, SKF specifies a shaft diameter range of 79.91-80.09 mm. The available sealing width and position of the seal lip should also be checked.
