21. Due to the multiple technical advantages, thrust bearings continue to be used in gyroscopes such as in the Hubble Telescope. 22. This type of mill consists of two types of rings separated by a series of large balls, like a thrust bearing . 23. For example, on radial thrust bearings the digits define the contact angle, or the presence of seals on any bearing type. 24. In a few years his invention completely revolutionised thrust bearing technology, particularly in the field of marine propulsion and steam turbines. 25. This can be avoided by the use of crossheads and also using thrust bearings to isolate the engine from end loads. 26. A drawback of the usual centrifugal design was the considerable axial force generated by the pump impeller, requiring a thrust bearing . 27. An RS Components geared dc servo motor was used, driven from the remote control receiver, and a thrust bearing and Oldham coupler. 28. In this type of actuator, thrust bearings and a freely rotating internally grooved bearing ring transfer loads between the rollers and the nut. 29. Kingsbury Inc . of Philadelphia won a $ 49, 392 contract from the Defense Supply Center in Columbus, Ohio, for thrust bearing shoes. 30. A disadvantage for the design of the rotor thrust bearing is no axial load from the impeller to balance that from the turbine.
