SKF 99193 Wear Sleeve 49.12-49.28mm Shaft Range

SKU CH-ATHM-KRS68

Stainless steel wear sleeve fits 49.12 to 49.28 mm shafts with 14.3 mm width on shaft and chromium-plated finish

  • ColorTransparent
  • Restores sealing surface on worn shafts
  • Fits 49.12–49.28 mm shaft diameters
  • Thin 0.28 mm stainless steel wall
  • Withstands 225 °F operating temperature
  • Chromium-plated finish resists corrosion

Engine Wear Sleeve for 49.12–49.28 mm Shafts

The SKF 99193 wear sleeve fits shafts between 49.12 and 49.28 millimetres. It is made from chromium-plated stainless steel for heavy industrial applications. The sleeve withstands temperatures up to 225 degrees Fahrenheit. It restores the sealing surface without replacing the shaft.

Fits Shaft and Frees Machining Time

The sleeve mounts directly onto the existing shaft within the stated diameter range. A flange diameter of 56.36 millimetres locates the sleeve while an overall width of 17.48 millimetres and a shaft-width of 14.3 millimetres set the installed position. Wall thickness is 0.28 millimetres. Tolerances of ±1.6 millimetres on outside diameter and ±0.8 millimetres on width accommodate normal shaft finish variation.

Replaces Shaft Rework or Full Replacement

This sleeve replaces the need to grind, plate or replace a worn shaft when the sealing journal is damaged. The jump is worth it when the shaft core remains straight and within the 49.12 to 49.28 millimetre limits. It is not for shafts outside this range, for temperatures above 225 degrees Fahrenheit or for applications requiring a non-metallic sleeve.

Questions about this item

What is the maximum temperature the SKF 99193 wear sleeve can withstand during continuous operation?

The sleeve is rated for a maximum temperature of 225 degrees Fahrenheit, making it suitable for heavy industrial applications where sustained heat is present.

How much heat does the sleeve generate or dissipate when installed on a shaft running all day?

As a passive stainless steel component with a 0.28 mm wall thickness and chromium-plated finish, the sleeve itself generates no heat and relies on the shaft assembly for thermal management.

What shaft diameter range must the existing shaft fall within for this sleeve to fit correctly?

The sleeve is designed for shafts measuring between 49.12 mm and 49.28 mm in diameter, with an outside diameter tolerance of +/- 1.6 mm.
