It’s time to change Black Oxide Coating.
The following case study began July 1st 2020 and was featured on March 31st 2021 on our news page. The COC CX2SN20-090L has been running at 1480 rpm for over 2 years now.
Previously they had to change a traditional SN500 plummer blocks every 3 months and our bearing has now lasted 26 months! The customer has saved over 8 times the cost of the bearings not to mention all the saved down time to uninstall and reinstall regular SN500 units.
They say the bearings aren’t as beautiful as the day they were installed but they are still running flawlessly and will continue to run with proper lubrication.
As you can see in the picture the black oxide coating on the CROSSLOC nuts is not doing anything to help protect against corrosion at all. This application is a landing conveyor near the coast where corrosion is a problem due to the salty atmosphere.
