High Temperature Wave Bearing Technology

NASTEC, Inc.

Brook Park, OH

A bearing with a wave shape sleeve over the journal operating thermally and dynamically stable at high temperature with a liquid lubricant

• Demonstrated stable operation of a wave bearing to temperature of 674°F (357°C), to loads of 825 lbs (3,670N) and to speeds of 30K RPM
• Validated an existing performance prediction code with precise experimental data from a wave bearing test rig
• Modified a NASA owned wave oil bearing test rig so that the shaft is now supported by two wave bearings

• NASTEC is actively seeking wave bearing technology business; web site is available - http://www.nastecinc.com
• The manufacturer of the high temperature liquid lubricant, DuPont, is actively assisting in the promotion of the wave bearing technology to the USAF, to other engine manufacturers and to a ground power generation company
• Discussions for application of high temperature wave bearing technology to high T4 propulsion systems have been held with GE, Williams International and Rolls Royce

• The NASA Ultra-Efficient Engine Technology Program is applying this wave bearing technology for use in further developing a geared turbofan
• A wave bearing has been proposed to the New Generation Launch Technology Program
