With technological advances in steam-assisted gravity drainage (SAGD), electric submersible pumps (ESPs) are operating at higher temperatures and placing increased demands on the thrust bearings in the seal/protector section and motor.
To sustain high load capacity at these high temperatures, Waukesha Bearings offers the Hidrax HT thrust bearing.
Hidrax HT bearings feature hard ceramic or ceramic-metallic composite (cermet) materials that can retain their surface hardness at oil bath temperatures of 300°C (572°F) and higher. The rated unit load of the Hidrax HT thrust bearing is 8 MPa (1160 psi).
The design uses the well-proven Hidrax platform, with durable ceramic/cermet lining on the tilting pads and the thrust collar.
