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.

Case Study – Alumina conveyor snub pulley

At an alumina refinery in Western Australia, snub pulley bearings on a train loading conveyor had to be replaced every 16 weeks due to premature failures caused by contamination, abrasive wear, and installation issues.

Our Australian distributor, Statewide Bearings, recommended upgrading to COC CX2SN11-050 units with protective covers and sealing improvements.

Result

The bearing life was extended from 16 weeks to 60 weeks — nearly 4 times longer.

Importantly, the bearings were still in excellent condition at inspection and could have continued running even longer.

Customer Feedback

• “Very easy to install”

• “Completed much faster than expected”

• “Using a torque wrench makes installation simple and accurate”

Cost Savings (per conveyor, per year)

• Before: AU$30,016

• After: AU$6,490

• Savings: AU$23,526

Key Benefit

Improved reliability significantly reduces the risk of unplanned downtime.

In this application, a full production stop could cost approximately AU$2.5 million per day, making reliability critical.
