We received this video from the cement company in Hokkaido Japan. This video was taken when they changed their SN520 to our CX2SN20-090L. And our bearings were recorded before the pulley covers are installed. They have been using SN520 for many years and the temparature of bearings was always their problem. Their regulation is the temparature of bearing should be under air temparature + 40℃ (104°F). The air temparature at this video was 14℃ (57°F) and SN was 70℃ (158°F) against 54℃ (129°F) their maximum temparature of regulation. Then they switched to our bearings and the temparature went up to 50℃ (122°F) first one hour and half and went down to 26℃ (79°F) steady after extra grease came out. Our bearings have been running about a month now and temparature stays low. They finally could resolve this problem.
Japanese industrial newspaper carries our SN bearings today.
CX2SN wins. It allows for the maximum bearing perforamnce. CROSSLOC™ is easy to install, easy to get off and allows for the greatest amount of up time. Our original triple lip seal allows longer bearing life and is more reliable. CX2SN saves you money in the long run with a lower total cost than traditonal SN5 type bearings.
