We received this video from a cement company in Hokkaido Japan. This video was taken when they changed their SN520 to our CX2SN20-090L. Our bearings were recorded before the pulley covers were installed. It’s a loading conveyor application using a 90 mm shaft and rotating at 1450 rpm. They have been using SN520 bearings for many years and the temperature of bearings was always a problem. Their regulation is that the temperature of the bearing should be under the air temperature of plus 40°C (104°F). The air temparature during this video was 14°C (57°F) and the SN520 was running at 70°C (158°F) against 54°C (129°F) their maximum temperature regulation. Then they switched to our bearings and the temperature went up to 50°C (122°F) for the first one hour and a half and went down to 26°C (79°F) and remained steady after the excess grease came purged. Our bearings have been running about a month now and operating temperature remains low. They finally have a solution to a problem that has been plaguing them for years.
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.
