Reliable motion with Skf roller

Practical benefits

Even distribution of load: The crowned outer surface prevents edge stresses and easily compensates for minor angular misalignments in your setup.
Protection against unwanted debris: Integrated metal shields on both sides retain lubricant effectively while keeping harmful dirt and dust out.
Convenient and quick relubrication: You can easily add fresh grease through the lubrication hole to extend overall service life.

In a nutshell

The right choise for

With the double-row Skf 305804 C-2Z cam roller, you achieve smooth, reliable motion across demanding conveyor lines, track systems, and cam drives. Its crowned outer ring profile prevents edge stresses and easily compensates for angular misalignments. Built with a double-row design, this yoke-type roller delivers exceptional load ratings and stability under heavy radial forces. The dual-sided 2Z metal shields keep dust and debris out while securing lubricant inside. When routine maintenance is required, the built-in lubrication hole in the inner ring allows you to quickly add grease, extending component service life and minimizing unexpected machinery downtime.
