SKF Speedi-Sleeve Avoids Expensive Repair

SKF Shaft Seal

A protective sleeve from SKF fits over a radial shaft to prevent abrasion — in the same way that a screen protector prevents damage to an expensive mobile phone.

In order to work efficiently, radial shaft seals must run against a smooth, round surface of the seal counterface. If the counterface becomes worn — such as a contaminant working itself under the sealing lip — the sealing system will begin to leak, simply replacing the seal will not be enough. First, the shaft will have to be repaired so that it is flush with the new seal.

The average cost of an SKF Speedi-Sleeve is around £15 — just 2.5% of the estimated £600 cost of repairing a worn shaft. A screen protector on a mobile phone works on the same principle; it is inexpensive, easy to replace, and prevents costly damages to the screen.

It can be used across a range of industries, including off-highway, mining or cement production, and on appliances including industrial pumps, gearboxes and motor shafts.

The SKF Speedi-Sleeve range is available in shaft diameters from 12 to 203.2mm and non-standard sizes can be made for diameters of 211 to 1,143mm.
