100 percent compatible with SN5

100 percent compatible with SN5

Only a few manufacturers in the world make unitized SN dimension metric units. However, our unitized SN is the only 100% compatible unit with standard SN5 in the world. Because the competitors use one size smaller bearings than standard SN5 bearings. Why? Because they use their adapter mount inserts which are same O.D. as their setscrew lock inserts although SN5 uses taper bore 222XX bearings with the adapters. Please check https://www.crossocean.com/interchange-guide/#SN5 The bearing sizes listed in red are smaller O.D. sized insert than standard SN5 bearings.

Their center heights and mounting pitches of housings are same as SN5, so they use larger housings with smaller insert to mach the dimensions. The smaller O.D. size has reduced load carrying capabilities and may lead to shorter bearing life. The long time SN5 users can’t expect the same bearing lives to those unitized SN5 units. We use the standard adapter sleeves in our patented CROSSLOC™ and this is why we are 100% compatible with SN5.

We are trying to be competitive on price as much as possible even with one size bigger inserts than others to achieve our goal. That is to replace all SN5 in the world with our SN to make them easier.

CX2SN20-090L

CX2SN20-090L

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.
