Thordon Bearing Users Unaffected by VGP Regulations

(December 19, 2013) It’s just another day for Thordon bearing users as their decision to use seawater lubricated propeller shaft bearings has ensured compliance in their oil to sea interfaces with the U.S. Environmental Protection Agency’s (EPA) new Vessel General Permit (VGP) regulations which came into effect today. 


Thordon prThordon COMPAC bearing with single key designopeller shaft bearings use the ultimate environmentally acceptable lubricant (EAL) - seawater.

Join the thousands of Thordon users unaffected by the ever-changing regulations on environmentally acceptable lubricants and make the switch to seawater lubricated bearings on board your vessel today!

And Thordon rudder bearings also eliminate the use of grease, another requirement of the VGP.



Video Highlights Conversion of a Main Guide Bearing from Oil to Water

Traditional hydro-turbines use an oil lubricated main guide bearing that can pose a risk of oil leaking down the shaft past the packing gland and contaminating the turbine’s discharge or tailwater. Many hydro-turbine operators have converted their lower main guide bearing so that it is now lubricated with the same water the turbine runs on and eliminates the oil discharges into the river. It also brings operational and maintenance advantages over the original oil system. Providing water as an alternative to oil lubrication is a long standing area of expertise for . . . to read the full article or to check out the video click here.
