Application

Application Challenges

Radial Load Capacity

Cylindrical rollers provide line contact and are used where radial load capacity is critical.

Edge Stress

Misalignment and deformation can concentrate stress at roller edges.

End-face Contact

Some bearing designs require controlled roller-end and flange contact.

High-speed Stability

Long rollers and high speeds require consistent geometry and cage compatibility.

Batch Grading

Rollers must be grouped by diameter for consistent bearing clearance and load distribution.
