Oil seals work
to retain vital lubricants, and exclude harmful contaminants,
allowing sensitive bearings and components to operate in a clean environment.
In dirty or
dusty environments particles can infiltrate the seal, and contaminate
the oil lubrication film, forming a damaging abrasive. This process
can result in grooving or polishing of the shaft, both of which will
prevent the oil film seal working properly. This results in a leaky
seal or contaminated lubricant.
traditional repair method is to either replace the shaft, or
remetalise the worn area. These alternatives are expensive or time consuming.
repair sleeve is a high quality, thin wall stainless steel sleeve
that is slid onto the shaft over the damaged portion. This operation
takes a few minutes, minimising plant downtime.
The sleeve is
so thin that the replacement seal used is normally the same size as
the original, and the finish of the sleeve is precision machined to
provide an excellent sealing surface.
can supply a range of repair sleeves in sizes ranging from 12mm to
over 1m diameter.
