Roller Bearings TRIZ Cases

Press-fit tire with sloped shoulders constrains bearing outer rings to eliminate axial gaps.

An inwardly tilted cage face creates a low-pressure region that reduces stirring resistance and rotary torque while maintaining adequate lubrication.

Four rows of tapered rollers on a shared outer raceway reduce manufacturing complexity and cost while maintaining high load capacity.

A concentric multi-axis actuator uses a two-stage cross roller bearing to support rotary output elements.

Intermediary members between the ring-shaped retainer and housing components reduce sliding wear while maintaining roller axial stability.

Extended axial ends form an annular oil film space that absorbs centrifugal loading, reducing wear between the bearing cage and inner ring.

Segmenting the outer ring into two parts connected by a plastic spacer separator reduces material usage and weight while maintaining structural integrity.

Flexible arms on a roller assembly maintain consistent compression and parallel engagement with peristaltic pump tubing to reduce flow pulsations.

An integrated elastomeric ring seal with retention hooks prevents lubricant leakage and foreign substance infiltration at the parting joint.

Curved abutting surfaces on a segmented bearing cage prevent segment separation and radial shifting, ensuring stable contact during pivoting.

Centrifugal oil throwing rings and labyrinth sealing lips redirect fluid flow to prevent leakage in conical roller bearings.

Bore holes in the coupling pin reduce bending stiffness, allowing elastic deformation that accommodates manufacturing tolerances and operational twisting loads.

An integrated lubricant branch structure within the bearing ring directs flow to multiple components, reducing installation space and system complexity.

Axial extension positions a large component attachment flange far from the rotor, reducing joint forces while maintaining small main shaft bearings.

Angled cable exit reduces strain from lubricant flow while protecting connectors in a recessed socket.

A suspension thrust bearing uses an elastomeric support cap to absorb vibrations from the vehicle spring.

Zero-degree load-transmitting thread flanks minimize radial force components, preventing bearing ring tilting during preload application.

Reinforcing beams in a rolling bearing spacer distribute compressive loads evenly, reducing deformation and extending service life under high compression.

Elastic dam section and eaves structure form an annular space to receive muddy water on the outer ring.

Removable raceway segments in the slew bearing enable direct roller replacement, reducing downtime and maintenance complexity during crane refurbishment.

An annular member suppresses rotational speed of the preload applying member, reducing wear on the component during high-speed operation.

A rolling bearing integrates an electric circuit via layered coatings directly onto the surface, eliminating bulky carriers.
