The problem - rotating shaft wear

Any rotating shaft in contact with a seal is subject to wear. The rate of shaft wear is dictated by a number of factors, but is increased by excessive heat, dust, shaft speed and lack of lubrication. A groove is gradually worn into the shaft by the seal lip, resulting in leakage. the damage to the shaft is permanent; a new seal will leak again in minutes if the shaft is not resurfaced in some way first.

The Choices

Historically, the options have been limited. Replacing the shaft with a new one is both extremely costly and time consuming. The machinery may require extensive dismantling and could be subject to a long period of downtime. The same applies to removing, remetalling, regrinding and replacing the worn shaft. Fitting a conventional wear sleeve saves time and money, but usually, the repair is only temporary and requires the use of oversize seals.

None of these options are ideal.

The solution?

Barnwell shaft repair kits (speedi sleeves) are the quickest, most effective way of performing a permanent repair on a seal-worn shaft, without having to subsequently use oversize seals. A wall of ultra thin stainless steel with no machine lead, each sleeve is engineered to form a perfect sealing surface.

An interference fit, the sleeve is pulled down to the shaft to cover the seal-worn region, with the aid of a removable flange and an application tool (supplied).

In most cases, because of its design, the sleeve can be installed without removing the shaft - significantly reducing downtime. the sleeve is hard wearing and corrosion free and offers a better quality sealing surface than a new shaft would.
