New Thorplas Thermoplastic Bearing Complements Thordon's Polymer Grades

Thordon Bearings Inc., a world leader in grease and oil-free bearing solutions has announced the  introduction of ThorPlas, a new propietary engineered (non-elastomer) thermoplastic bearing.

ThorPlas has been formulated to complement the existing range of Thordon elastomer bearing grades and significantly expands the range of applications where Thordon bearings can be specified, while still maintaining many of the recognized Thordon performance benefits.

ThordPlas offers the following advantages:

  • Increased strength and rigidity allowing working pressures in an interference fit bearing up to 31 MPa (4500 psi)

  • Improved ability to operate at elevated temperatures up to 80°C (175°F) in water

  • Improved chemical resistance in all major chemical product categories

  • Eliminates grease

  • Easily machined and no nuisance dust

  • Scrap can be recycled and reused.

As part of Thordon's StageGate New Product Development program, Thordon has been test marketing ThorPlas since 2003 and has many installations in operation working successfully. Following are some of the test applications:

End User: Berman Brothers, FL, USA
Application: Grapple Bearing - Scrap Metal Recycling
Thorplas bearings lasted 5 months compared to nylon's life of 3 weeks

End User: Kody Marine, LA, USA
Application: Rudder Tiller arm bushings on work boats
Previously greased; operating dry after Thorplas installation

End User: New York State Electric & Gas, Saranac River, NY, USA
Application: Wicket Gate Bearings

End User: Alabama Electric Cooperative, USA
Application: 3MW Hydroelectric Plant

ThorPlas has demonstrated exceptional wear and abrasion resistance and has one of the lowest wear rates among nearly all rigid polymers. Due to its ratio of static to dynamic co-efficient of friction, it does not exhibit any stick slip effect, instead, it provides smooth, quiet, stable operation in demanding applications, says Ingrid Muschta, Product Manager for Thordon.
