Roller Bearings TRIZ Cases

Multi-speed power measurements improve wheel bearing preload calculation and pass/fail judgment by reducing grease and seal resistance errors.

Convex axial ends and a low-friction composite layer form a film during sliding to cut stick-slip, vibration, and friction in suspension bearings.

A flexible bladder and conduit stabilize sealed gearcase or wheel hub pressure to prevent lubricant loss, seal damage, and contaminant ingress.

A wedge-shaped sleeve closes radial bearing clearance to prevent misalignment, raise stiffness, and reduce outer race orbiting.

A frustoconical flinger creates a labyrinth gap that blocks brake dust and oil while retaining lubricant and minimizing wheel bearing friction.

A hollow shaft and sealed cooling chambers remove bearing heat in a boat anti-roll gyroscope while preserving compact structure and low friction.

A rotor fixing mechanism with tapered surfaces and external bolts enables bearing grease renewal and replacement without removing the rotor.

A rigid annular shield blocks dust and metal shavings from the primary seal, while drain passages clear buildup to extend wheel bearing life.

Two coaxial input shafts and lockable rolling bearings maintain continuous torque during motorcycle shifts without DCT weight or electronics.

Two parallel input shafts and speed-locked roller bearings enable seamless motorcycle shifts without torque interruption or electronic control.

An engagement contour on the actuator housing counter-holds torque, enabling secure bearing screw assembly without housing rotation damage.

Dual axial preload and an oil cavity keep a gas turbine shaft stable during overhaul while damping bearing skidding in operation.

Curved contact protrusions in a segmented bearing cage reduce lubricant scraping and friction at rolling-element end surfaces, extending wear life.

A spring plate with a soft conductive contact grounds the rotating ring to prevent bearing electrolysis while reducing abrasion powder and damage.

Gas jets disrupt bearing-cavity vortices to lower seal vibration and avoid resonance-driven wear in gas turbine engine seals.

A shaped cage side surface and controlled roller gap reduce interference, slippage, and skew to extend cylindrical roller bearing life.

Ring-mounted distance sensing tracks radial displacement to calculate bearing deflection in real time and warn of overload before damage.

Sensors track bearing geometry changes to detect cracks and deformation early, helping wind turbines avoid catastrophic bearing failure.

Gothic arch holding portions and controlled wedge angles prevent roller wedging during radial cage movement, reducing column damage.

Slots and inward bosses lock a gas turbine bearing race without shaft threading, cutting length, machining complexity, and interference.

Embedded sensors inside rolling elements detect bearing damage and contamination early, even when vibration monitoring fails at low speed or high noise.

Partial overmolding and a retaining element secure the bearing while limiting heat and pressure exposure during assembly.

A double-rim bearing cage holds both axial washers form-fit to cut radial guide tolerance, noise, and vibration-driven dismantling.

An opposing-thread locking ring stops a threaded bearing adjuster from loosening, preserving preload and shaft axial stability.
