COC CROSSLOC™ Draws Strong Interest at Steinexpo 2026

Our German distributor, Hagenauer, exhibited COC products at Steinexpo 2026, held September 2–5 in Germany.

Unlike a conventional trade show, Steinexpo is held directly in a quarry, creating a unique environment where visitors can experience quarrying and processing equipment in the setting where it is actually used. Held every three years, the event attracts more than 60,000 visitors from the quarrying and mineral processing industries.

At the Hagenauer booth, the main focus was a hands-on comparison between a conventional SN bearing housing and the COC CX2SN with CROSSLOC™.

A demonstration table clearly showed the difference in installation. On one side were the components and tools required to mount a conventional SN bearing unit. On the other was the CX2SN with CROSSLOC™, requiring only a hex key and torque wrench for installation—no feeler gauges, marker, or hammer required.

Visitors were also invited to install a shaft into a CX2SN10-045E themselves, giving them the opportunity to experience firsthand how simple CROSSLOC™ installation can be.

The demonstration attracted strong interest throughout the show, particularly from maintenance professionals in the quarrying industry, and Hagenauer received very positive feedback on COC products.

We would like to thank the Hagenauer team for representing COC and giving so many visitors the opportunity to experience CROSSLOC™ technology firsthand.

We look forward to Steinexpo 2029!

Introducing the New CROSSLOC™ SAFD Series

COC is pleased to introduce the new CROSSLOC™ SAFD Series, expanding our SAF product range with split ductile iron housing units for shaft sizes up to 7 inches.

Designed for demanding applications requiring greater strength and durability, the SAFD series features robust split ductile iron housings that are easily identified by their distinctive dark blue finish. The larger housing sizes provide a reliable solution for heavy-duty conveyors, fans, crushers, and other industrial equipment where standard cast iron housings may not be sufficient.

Like all CROSSLOC™ mounted units, the SAFD series offers fast and reliable installation. Large SAFD units utilize our proven CROSSLOC™ locking system with 6 or 8 cap screws tightened in a star pattern, providing secure 360-degree shaft clamping without the installation difficulties associated with conventional locknut systems.

The SAFD housings are equipped with dual grease ports, allowing customers to use either side for relubrication or to install condition monitoring sensors without additional machining.

In addition, the new CX4SAFD36 and CX4SAFD38 inserts feature an innovative adjustable sleeve design. By simply rotating the collar, the sleeve inside diameter can be adjusted to accommodate variations in shaft size, making installation easier and improving mounting flexibility in the field.

With shaft sizes available up to 7 inches, durable ductile iron construction, dual grease ports, and the proven CROSSLOC™ locking system, the new SAFD series delivers a stronger, smarter solution for large mounted bearing applications.

This year’s FOOMA JAPAN was held at Tokyo Big Sight from June 2 to 5.

Unfortunately, visitor attendance dropped significantly on June 3 due to an unseasonal typhoon. However, we were pleased to welcome many visitors on the other days of the exhibition. Thank you to everyone who stopped by our booth.

One of our new highlights this year was the introduction of the UC-style option. However, for customers who already appreciate the benefits of OCCLOC, this addition did not seem to generate much interest, as they continue to prefer the OCCLOC locking system.

It’s a stressful world situation these days.

At this facility, our SAF unit was used for approximately 1.5 years before being replaced for the first time.
According to the maintenance team, they simply loosened the cap bolts until they heard a “pop” from the adapter, and the bearing came right off the shaft.

Previously, removal required 2–3 people, along with cutting using a grinder or torch. This also required a hot work permit from the safety department and a fire watch (a fire spotter who monitors for sparks and fire hazards) to remain on-site for several hours.
Eliminating this process was highly appreciated by the customer.

This represents a major improvement in safety, time, and labor.
