Supplier: NTN Bearing Corporation
Description: supplementary seals, closures, or protective devices. This design also offers the lowest possible manufacturing costs to the end user. Shielded ball bearings are protected on one or both sides by metal shields that are fastened to the outer ring. This close clearance labyrinth seal retains
- Bearing Type: Radial Ball Bearing
- Bore Size: 1.77 inch
- Outside Diameter: 3.35 inch
- Dynamic Radial Load: 7350 lbs
Description: As steam turbines age, the seals wear, causing excessive radial clearances that result in steam leakage. Worn labyrinth seals are typically and mainly caused by rubs that occur during startup due to high vibration and thermal distortion. The end result is a bowed rotor, displacing the blades
