Rolling Contact Bearings TRIZ Cases

Split bearing mounting uses adhesive for axial loads and an O-ring for radial absorption, improving high-speed motor reliability.

A diametrically magnetized ring rotor and axial stator layout raise torque-to-weight ratio and energy efficiency in circulatory support motors.

Axially movable, preloaded freewheel discs in a bicycle hub distribute load to reduce tilting, wear, and deformation under high loads.

GPS-triggered sensing records bearing data only on suitable track sections, improving signal quality while extending battery life.

A gas-drainage pin vents trapped air in thin bearing cover walls, preventing burn marks and short shots while preserving sensor accuracy.

A pressure-controlled assembly chamber seals wheel bearings at a preset atmosphere to prevent contamination and avoid torque rise from seal lip drag.

A stop-ring preload tool applies repeatable bearing compression and aligns the lock nut when seal drag and limited access hinder assembly.

Gaps between segmented sensor support walls discharge mud and moisture while protrusions preserve rigidity and protect the wheel speed sensor.

A contact seal with a face plate and anti-rotation pin protects starter-generator bearings from frictional heat, oil leakage, and debris ingress.

A dual-seal wheel bearing isolates the inner ring from water and debris, preventing stress corrosion cracks while easing assembly.

Cutout and latch features in the wheel bearing cage raise ball count while easing ball insertion and limiting pillar deformation.

A single housing and rotor-to-gear-shaft bearing layout cuts bearing losses, parts count, weight, and assembly complexity.

Outer-end insertion and fastening let wheel hub bearings be preloaded, serviced, and replaced without inner upright access.

An axial rim-centering seat and nested seal space speed wheel mounting, improve centering accuracy, and protect the bearing in a compact hub layout.

By measuring inner ring expansion before and after fitting, this case improves hub unit bearing preload control and helps balance life, torque, and rigidity.

A sheet metal ring maintains radial seal pressure between wheel bearing inner rings, preventing oil ingress even during heating and cornering.

A bearing stop advances the seal sleeve along the spindle without a sacrificial bumper, cutting heat, drag torque, and seal wear.

Electrodes and an insulating film inside the bearing generate current during rotation, enabling compact state sensing without external sensors.

Segmented sub-washers let engineers adjust catcher bearing gaps without full bracket disassembly, improving rotor alignment and failure protection.

A radial labyrinth and flexible seal lips help truck hub bearings retain lubricant, block dust ingress, and cut friction-driven power loss.

A drive-gear adjuster changes axle bearing preload from outside the housing, avoiding shims, disassembly, and axial positioning rework.

A separated antenna chamber avoids explosion-proof medium losses, enabling Nc sealing and long-distance wireless monitoring.

A sealed dry chamber and spindle duct bring compressed air through the hub, enabling central tire inflation without disturbing oil-bath lubrication.
