Bearing Isolators

Bearing isolators provide containment and protection from external contamination for bearing lubrication. Before bearing isolators, most rotating equipment bearings were protected with rubber lip seals or stationary labyrinths. Today a wide variety of rotating equipment still uses lip seals or dual labyrinths to contain and protect bearing lubrication. In most of these applications the performance of these devices fails to meet today’s MTBR objectives.

In virtually all rotating equipment applications lip seals lose their functionality within six months. Due to the elastomeric material running against a metallic rotating shaft, the lip seal can also damage the shaft.

Straight labyrinths are still used in many pieces of rotating equipment in the O&G and petrochemical and power industries such as pumps and steam turbines. However, IsoMag magnetic bearing isolators now provide a superior technology. With a more effective bearing lubrication containment, as well as enhanced protection from external contamination end-users achieve an improved MTBR.
