What are the differences between cylindrical or crowned outer ring rollers?

1. Structural Features and Core Differences

Outer Ring Profile Design --

Cylindrical Outer Ring: The outer ring of the cylindrical outer ring roller is a standard cylinder with a constant diameter and a flat surface. The contact form is line contact, which is suitable for scenes with high requirements for installation accuracy.

Crown Outer Ring: The outer ring is symmetrically arc-shaped (similar to the crown profile), and the contact form is surface contact. This design can adaptively compensate for installation deviations and reduce edge stress concentration.

Internal Component Composition --

Cylindrical or crowned outer ring rollers both include thick-walled outer rings, rolling elements and cages.

With Inner Ring Type: Suitable for occasions requiring axial guidance (such as cam transmission), the inner ring can be installed separately.

Without Inner Ring Type: The shaft or bolt needs to be hardened and ground, the structure is more compact, and it is suitable for scenes with limited space.
