DUNLOP Spherical roller bearings are non-separable, double row radial bearings.
Both rows of barrel shaped rollers rotate in parallel, within the spherical outer ring. This allows excellent alignment compensation caused by machining and mounting errors, between the shaft and housing.
Spherical roller bearings are typical bearings for heavy machinery and mining. Typically these bearings support a rotating shaft in the bore of the inner ring, which requires movement at an angle as well as rotationally.
They are designed to work in applications where severe misalignment exists, whether from mounting or shaft deflection and with heavy radial loads and axial loads in either direction. They are extremely resistant to shock loads and their self-aligning feature allows full capacity loading, despite shaft deflection.
Due to the poor kinematics behaviours, spherical roller bearings are only suitable for operating at low to medium speeds. Spherical roller bearings are produced open design as standard.
