Bearing Sensor Installation
Install Case Style A sensor just below the babbitt layer, then puddle the babbitt metal over the sensor tip and smooth.
Bearing Sensor Installation
The Top Hat Spring Style retaining ring allows sping loading with the spring and retaining clip. Slide the spring and ring over the leads, insert the sensor tip into a milled hole, and push down on the retaining ring to compress the spring and secure the sensor.
Bearing Sensor Installation
Bond with epoxy inside bearing shoe. Locate near the babbit face for most accurate readings.Bearing RTD
Bearing RTDs are designed for areas where there are space limitations. They are small, compact and are often used to detect temperature increases in bearings, thrust bearing plates, shafts and motor windings. They are miniature low mass sensors which are fast responding. Bearing sensors are manufactured using thin film technology and by design are tip sensitive and vibration resistant. They can be spring loaded into a bearing housing or held in position with a high temperature epoxy resin.

Composed of a positive leg, which is approximately 90% nickel, 10 chromium and a negative leg, which is approximately 95% nickel, 2% aluminum, 2% manganese and 1% silicon.
When protected by compacted mineral insulation and appropriate outer sheath, Type T is usable from 0 to 350°C, (32 to 662°F). Type T is very stable and is used in a wide variety of cryogenic and low temperature applications. For applications below 0°C, (32°F) special selection of alloys are usually required.

Bearing Temperature
Condition monitoring has proven important in the installation and maintenance of all types of turbomachinery. Bearing temperature is primarily important because bearings are the critical links between the rotating and stationary components in a machine. If temperatures are taken in the correct location, then Babbitt metal temperatures can be the best indicators of a bearing's operating condition.
Causes Of Bearing Failure
Most bearing failures such as flaking and pitting, spalling, unusual wear patterns, rust and corrosion, creeping, skewing and others are usually attributed to a relatively small group of causes that are often interrelated and correctable. These causes include lubrication, mounting, operational stress and bearing selection and environmental influence.
Don't Let This Happen To You
A bearing failure will not only mean a compressor shutdown; it could also result in secondary or peripheral damage to costly internal parts. Early detection of a bearing failure may only result in an outage lasting a few days, but an undetected failure, causing major internal damage, can force an outage for weeks or months.
Thrust Bearings
Thrust bearings offerings include fixed profile designs for lightly-loaded applications and advanced tilting pad solutions for more demanding, high-load, high-speed applications. Combination thrust/journal designs are also available for applications with limited axial space.
Tilting pad thrust bearings are specially engineered for reduced power loss, oil flow and pad temperatures...for the most reliable and efficient machine performance.
