Mechanical Seals and Seal Support Systems
Bearing Isolators - Bearing Gard
About this product
The Bearing Gard incorporates innovative static sealing technology to provide sealing protection under shut-off conditions. An internal O-ring between the rotor and stator prevents contamination from entering the bearing housing when the equipment is not operating. When the equipment is started, the static sealing system quickly transitions to non-contacting operation for permanent non-wearing performance.
Features and Benefits
- Static protection is assured by an internal O-ring between the rotor and stator.
- Dynamic protection is provided by a tortuous labyrinth that effectively repels severe environmental conditions.
- Standard design accommodates axial shaft movement of 0.63 mm (0.025 in) TIR
- Static sealing quickly transitions to non-contacting operation for consistent performance and will not wear on the shaft or equipment.
- Oil retention features work to keep oil inside the bearings and off the ground.
