Grades and configurations
Thorplas© ( Blue )
Non-polymeric, homogeneous, specifically developed by Thordon Bearings for high pressure applications.
- Maximum dynamic working pressure to 31.0 Mpa ( 4500 psi ); static pressures to 45.0Mpa ( 6500 psi )
- easily machined without affecting low coefficient of friction ( typically 0.10 – 0.17 )
- very low wear in non-abrasive environments
- maximum continuous service temperature of 80°C ( 176°F ) in water and 110°C ( 230°F ) dry
- excellent dry start capability as a vertical pump bearing
- reasonable abrasion resistance – less than Thordon elastomer grades, but better than bronze, epoxy phenolics and many other non-metallic bearing materials
- improved chemical resistance in most chemical product categories compared to elastomeric grades
Thordon SXL ( Off-WHITE )
Excellent at dry start-up with a friction coefficient lower than other Thordon Bearings polymer grades
- Low coefficient of friction ( typically 0.10-0.20 )
- Higher dry PV ( Pressure Velocity ) rating than XL
- Higher resistance to abrasion than XL in wet applications; good abrasion resistance operating dry
- Dry start-up capability as a vertical pump bearing
- High resistance to shock loading and vibration
Thordon XL ( Black )
Used in different industrials applications, show a similar abrasive resistance than SXL
- Low coefficient of friction ( typically 0.20-0.25 )
- High resistance to abrasion in dry applications
- High resistance to shock loading and vibration
Thordon HPSXL ( Grey )
For high pressure applications, since HPSXL TRAXL is glued in a metallic housing
- Maximum dynamic working pressure to 15.0 Mpa ( 2175 psi ) in limited motion as a homogeneous material
- HPSXL TRAXL has maximum dynamic working pressure to 55.0Mpa (8000 psi) in limited motion
- Lowest coefficient of friction ( typically 0.06-0.12 )
- Moderately abrasion resistant ( lower abrasion resistance than XL or SXL )
- High resistance to shock loading and vibration
Thordon Composite ( Yellow & Black )
A two layers bearings designed to be specifically used in highly abrasive environments
- Used in rotating applications in abrasive water conditions such as pump and dredge bearings
- Outstanding abrasion resistance – two or more times that of rubber
- Significantly lower coefficient of friction than rubber
- Higher resilience and stiffness than rubber
- Available with either yellow polymer or metal bearing shells
Thordon Compac ( Orange )
Polymeric bushings specifically developed for marine propulsion shafts
- Unique design that helps to develop the hydrodynamic film
- Low friction providing easier startups
- Water lubricated bearings that eliminates the need of using oil in the sterntube
- No sterntube aft seal required since the water flow goes through it
- Approved by major classification societies
- The use a tapered keys allows inspection of propeller shaft without removal
Thorflex (Thorseals)
Flexible polymers with high mechanical strength developed for sealing applications.
- Long life due to Thorseal polymer self-lubricating properties
- Superior Yield strength than other seals on the market
- High resistance to permanent deformation
- Operating temperature from -50 ˚C (-60 ˚F) to 90 ˚C (195 ˚F)
- Operating Pressure 0 – 15,000 PSI (0-103Mpa)
- Custom made to fit the needs of of your specific applications
