BS-E65 (previously SLBM-A/B) bellow components is a stationary welded metal bellow component. The stationary design make it more suitable for operations with relatively high speed rotation and / or relatively large shaft-to-chamber misalignment. External drive lug is used in this component to substantially reduce the stress to the metal bellows.
BS-E65 has similar installation size as Eagle Burgmann MFL65.

| Standard | Optional | |
|---|---|---|
| Bellows: | Inconel 718 | 17-4 PH, HC-276 |
| Secondary Seal: | -- | -- |
| Seal Face: | Antimony Impregnated Carbon Garphite | SiC |
| Ring Adaptor: | Carp. 42 | Duplex |
| Adaptor: | SS 316L | SS 304 |
| Non-Concurrent* Limit | ||
|---|---|---|
| Temperatures: | Inconel 718: -40oF to 750oF (-40oC to 400oC) 17-4 PH: -4oF to 392oF (-20oC to 200oC) | |
| Pressure: | Externally pressurized: Up to 363 psi / 25 bar. | |
