Laser marked instruction of CROSSLOC™

Laser marked instruction of CROSSLOC™

We are going to add the laser marked instruction of CROSSLOC™ on the nut.

CROSSLOC™ is very easy to lock and unlock. It’s just tightening cap screws to lock and loosening cap screws to unlock. However, we want people to understand this system better to avoid possible failure and be safer on site.

We will add these instruction in the several languages in the scanned page of the QR codes on the housing as well.

<Information for your technical support team>
There are two nuts for this locking system and the inside nut connects with the inner ring and outside nut connects with the adapter sleeve. These two nuts are connected with four (six) cap screws and the outside nut with adapter sleeve is pulled and pushed by cap screws to lock and unlock. The adapter sleeve needs to be pulled to lock and we use the left-hand cap screws to turn clockwise to pull and turn counterclockwise to push. When you tighten the cap screws, the gap between two nuts gets bigger and the adapter sleeve is moving towards the outside. When you loosen the cap screws, the gap will be smaller and the adapter sleeve is moving towards the inside. The outside nut should move parallel to the inside nut to avoid the cap screws twisting and getting damaged. This is why the cap screws are tightened in a star pattern and repeated. You may need to repeat this several times to tighten all the cap screws perfectly, this is a very standard way as seen with automobile wheels.

When you want to unlock CROSSLOC™, loosening and turning counterclockwise is needed. They are the same left rotation but turning counterclockwise does not loosen. Loosen all cap screws to be freed first. Then you need to push the outside nut to release the adapter sleeve from the inner ring. Turn the cap screws counterclockwise in a star pattern and repeat until dismounted. It’s same as locking and the outside nut should move parallelly.

UNLOCK

The outside nut should move parallel to the inside nut.

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.
