Bearings can be produced by freeze / Bond fitting any of the above Thordon Grades into a metallic housing. Use of a Thordon lining in a metallic housing produces a stiffer bearing that requires significantly less running clearance than other non-metallic bearings. Originally developed to meet the needs of the nuclear power industry, this design is now specified in many other applications.

Thermoplastic material developed by Thordon specifically as a homogeneous high pressure bearings that offers dry start up capability and has a maximum dynamic work pressure. It has a very low wear in non-abrasive environments, reasonable abrasion resistance - less than Thordon elastomeric grades , but better than bronze , epoxy phenolics and many other non - metallic bearing materials and higher temperature resistance i.e. 80 Degree Celcius in wet condition.

Specifically formulated to provide outstanding wear life in abrasive operating conditions, Composite often outperforms other bearings by a factor of several times. Extremely cost effective in abrasive conditions, Thordon Composite exhibits a dry coefficient of friction lower than rubber. Composite bearings are available in a wide range of sizes in grooved configurations only.
The preferred choice for dry start-up operation, SXL offers a lower dry coefficient of friction and better wear life and abrasive resistance compared to XL. Thordon SXL bearings have been successfully used in many deep well pumps where start-up dry running periods in excess of one minute are experienced. SXL bearings are available in a wide range of sizes in both grooved and ungrooved configurations.
