Mechanical Seals and Seal Support Systems
Bearing Isolators - Bearing Gard for Steam Turbines
About this product
The Bearing Gard for steam turbines is specifically design for these unique applications improve equipment reliability and reduce maintenance by creating a strong barrier against steam ingress, which causes oil contamination.
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 housing, even with oil-injected bearings
