Typically, the counterface becomes scored when a contaminant particle is
caught under the sealing lip and abrades a track as the shaft rotates. As this
continues, the seal will enable more particles to pass or get stuck, and seal
efficiency deteriorates, eventually leading to malfunction of the component that
the seal is meant to protect. To rectify the situation, it is necessary to
repair the shaft surface since a seal replacement will not be sufficient. To
repair the shaft, it is usually necessary to disassemble the machine in order to
either replace the shaft or grind down the counterface until it is again within bearings specification.
SKF SPEEDI-SLEEVE is a well-proven solution to overcome problems with worn
shafts without having to disassemble the shaft or changing the seal dimensions,
while offering an excellent sealing surface. Now, SKF has developed a new
generation SKF SPEEDI-SLEEVE with features providing an even further enhanced
sealing system performance. Using SKF SPEEDI-SLEEVE, combined with an SKF radial
shaft seal, customers will benefit from a more consistent and increased
durability of the sealing system. This will enable a more stable maintenance
planning with improved predictability of the system service life. SKF bearings SPEEDI-SLEEVE is available for shaft diameters up
to approximately 203 mm. For larger shaft diameters, SKF offers wear sleeves for
heavy industrial applications, LDSLV3 and LDSLV4. For detailed information
regarding LDSLV designs.
If the shaft cannot be ground and hardened as a seal counterface or if a
replaceable seal counterface is required, needle roller bearing inner rings with
non-directionally ground raceway can be used.

Plain bearings and sleeve bearings (also referred to as bushings or journal
bearings) are used to constrain, guide or reduce friction in rotary or linear
applications. They function via a sliding action instead of the rolling action
used by ball, roller, and needle bearings. Plain bearings and sleeve bearings
are made from a variety of materials and are often self-lubricating to provide
smooth operation and greater durability. They consist of one part that is built
up of many types of materials, layered and combined into a load carrying system.
Plain and [sleeve
bearings] are often very inexpensive, compact, lightweight, and have a high
load-carrying capacity.
