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. |
