The CXC4P22-407 is still going strong after 2 years, while the competitor’s units only lasted 6 to 8 weeks. The COC turtle just won’t die-built to last!

As seen in the video, it’s a very demanding application. We believe this dramatic improvement in lifespan is thanks to COC’s unique triple-lip self-aligning seal and the CROSSLOC locking system. The adapter-style locking design provides 360-degree clamping, delivering superior performance by resisting vibration without damaging the shaft. In contrast, conventional locknut systems are difficult to install correctly and often lead to improper mounting. With CROSSLOC, anyone can install the bearing easily and reliably, reducing the risk of installation errors and extending bearing life.

This is feedback from Brazil.
Our CX2SN22-100 units have been running in chain mills for the last two years, while the competitor’s units last only one year.

GEAPS was a very busy show with lots of new opportunities.
We gave away YETI cooler bags for $10K stock orders, and many of them were taken.

4 Bolt Flange Type E Housings

We have added Type E 4-bolt flange housing sizes ranging from 2-7/16” to 4”. These additions were prompted by many requests from the US and some from other countries. They are slightly larger than standard 4-bolt flange housings, and we modified the design for easier identification.

They were impressed with how straightforward the locking collar was to use and also appreciated the QR code. The maintenance supervisor mentioned that after the fan was restarted, it hadn’t run this smoothly since it was new.

The China International Bearing Industry Exhibition, which had been postponed for four years due to COVID-19, was finally held from November 25 to 28 at the National Exhibition and Convention Center in Shanghai.

We had the pleasure of reconnecting with many old friends and customers and were excited to introduce our products at the event. The team from COC USA also joined the show and thoroughly enjoyed their first trip to China.

We have added an additional line to the laser marking instructions for the MOUNT on the CXC CLOSSLOC nut, as shown by the red arrow in the picture above.

When the shaft rotates rapidly counterclockwise, CXC CROSSLOC nuts are at increased risk of loosening and pulling the sleeve. For safety, ensure the setscrew is tightened firmly before use. The factory has not tightened it fully to avoid obstructing the shaft during installation.

The rusted black oxide nuts were replaced with zinc-nickel plated ones, which are highly resistant to rust.

Saniline Case Study in a Leading Domestic Beverage Factory

Although IP69K certification is typically conducted with bearings at rest, the following case demonstrates that waterproofing remains highly effective even during operation. The following report uses part of an internal report from a certain beverage factory dated June 2024.

April 2021: Due to conveyor replacement work associated with the installation of a foreign object inspection machine, the bearings in the affected area were changed to stainless steel bearing units from Company A, considering the impact of water spray, etc.

Company A’s stainless steel square flange unit, inner diameter 40 mm, with cover and NBR rubber plate between the unit and conveyor frame.

July 2021: The conveyor drive shaft stopped due to bearing failure. The failure was thought to be caused by a large amount of water entering the bearings. Although the use of corrosion-resistant stainless steel bearing units from Company A was anticipated, they failed in about four months. Downtime: approximately 200 minutes.
Restored with the same product from Company A.

Estimated Cause: Water from spraying and moisture from the conveyor scattered, and foam or hot water from equipment cleaning reached the bearings, causing moisture to penetrate inside. This likely led to grease degradation and oil film breakdown. The removed bearings were completely locked up.
Discussions with Company A did not yield effective countermeasures.

January 2022: Replaced with COC’s Saniline Series OCSF208.
The bearings from Company A removed at this time were dry, with a gritty feeling when turned by hand.

May 2024: After more than 18 months of use, no failures have occurred. Inspections using a stethoscope during idle operation showed no abnormalities.

Supplementary results from actual tests:
In October 2022, the seals were removed from a COC Saniline Series bearing after approximately 10 months of use for inspection.
The outer slinger was removed, and the grease sealed between the seals remained intact, with no water ingress.
The inner seal was also removed, and no water contamination was found, with a sufficient amount of grease still present inside the bearing.

Evaluation:
Compared to Company A’s stainless steel bearing units, which showed signs of failure or broke down after 4-5 months, the current bearings have lasted almost five times longer. The inspection results after about 10 months of use were also favorable.

With excellent waterproofing, these bearings have proven durable in harsh environments, making them highly effective as a preventive measure against recurrence. The superiority of COC’s bearings has been confirmed, and they are now being gradually applied to other conveyors as well.

Summary of Benefits:

1. Reduced downtime: Assuming continued use of Company A’s bearings, the risk of failure would persist around every four months. After switching to COC bearings, there have been no failures for over two years.

2. Reduced labor hours: Bearing replacement required 3 people x 3 hours. Performing this task three times a year (every 4 months) would have taken 27 hours, which has been saved.

3. Reduced unplanned repair costs: Fewer repairs also lower the risk of work-related injuries.
