Applications:
Machine Tools: These bearings are frequently used in precision machine tools, where the housing or casing is machined to high tolerances to act as the outer raceway.

Automotive Transmissions: Cylindrical roller bearings without an outer ring are used in some high-performance transmissions, where the gearbox housing can serve as the outer raceway, allowing for a more compact and robust design.

Heavy Machinery: In some heavy-duty equipment, this type of bearing allows for a more simplified design by incorporating the bearing raceway directly into the machine's structure, reducing the number of components.

Electric Motors: In high-speed motors, the elimination of the outer ring can reduce weight and friction, improving overall efficiency and reducing maintenance needs.

Advantages:
Reduced Weight and Space: Without the outer ring, the overall bearing assembly can be lighter and more compact.

Cost Savings: In some applications, using the housing as the raceway can reduce the number of components, leading to cost savings in both manufacturing and maintenance.

Customization for Specific Applications: The ability to customize the housing as the raceway allows for specific application designs tailored to the needs of the machinery.

Considerations:Precision Machining Required: The housing must be machined to very tight tolerances to serve as the raceway, with a smooth surface finish to prevent premature wear.

Load Distribution: The lack of an outer ring places more responsibility on the housing to distribute loads evenly. Improper machining or design can lead to uneven load distribution and premature bearing failure.
