Linear Bearings TRIZ Cases

Radial distributing grooves segment pressurized gas paths to prevent turbulence and vibration, achieving 10 nm positioning accuracy.

Profiled shaft uses elastic elements in guide rail recesses to exert preload on ball cages for continuous play compensation.

A linear motor slider integrates an oil reservoir and push body to deliver lubricant directly to rolling sections.

Integrated hollow frame half return members eliminate level differences at conjunctions to prevent noise and extend the life of the linear actuator.

A linear guideway retainer positions two circulation tubes using offset openings and wedged supporting members.

High-performance thermoplastic coatings reduce friction and wear while maintaining mechanical strength beyond the glass transition temperature.

An elastomer guide part integrates longitudinal sealing lips with holding projections to secure rolling bodies within a circulation channel.

An inclined rolling zone converts actuator motion into clamping force, resolving the trade-off between high force and short reaction times.

Protrusion portions on the attachment plate apply counteracting force to prevent molding shrinkage gaps in linear guide devices.

Snap-fit connecting portions enable rapid replacement of the oil-storage unit, solving limited lubrication duration in existing designs.

Spring-loaded detents lock clamping devices in stable positions without continuous energy, preventing uncontrolled movement during power failures.

A hydrostatic slide device uses four lateral bearings to support reciprocal movement.

Plastic deformation of pit edges creates bending portions that restrain spacer slippage and dust contamination during thermal cycling.

Elastic sections in a linear slide dust protection plate adjust contact pressure to prevent wear gaps and reduce replacement downtime.

Dynamic pressing units adjust recessed part positions as lubricant content decreases, maintaining consistent pressing force and reliable lubrication.

Controlling mounting surface roughness to 0.01-0.1 microns prevents foot portion deformation and vibration, ensuring stable clearance for high precision.

Elongated insertion holes and detachable holders reduce assembly time by eliminating pressing force requirements during rolling element placement.

A linear motion guide wiper uses a spring-biased latch to anchor securely to an end cap without tools.

Spherical spacer surfaces interlace with belt holes to retain balls and store lubricant, eliminating ragged edges that cause friction in recirculating passages.

A single roller guide uses a deformable circumferential surface to eliminate play and blocking in vehicle seats.

An integrated oil transmitting member absorbs lubricant from a container and delivers it to the screw guideway, eliminating manual maintenance intervals.

A machine tool sliding surface with a continuously extending recess retains lubricant, preventing flow-out and ensuring smooth movement of the saddle.

Fall prevention portions reduce retaining portion openings to prevent rolling element ejection caused by resin warping during molding.

An inside seal with a metallic core and sealing lips prevents foreign material entry into load-carrying races while maintaining compact construction.

A U-shaped extruded actuator uses dovetail recesses and wedged rail members for secure fastening.

Constant-radius curved turnaround passages in end caps resolve wobble and bumpy motion caused by irregular paths, enabling high-velocity sliding.

Single-piece roller rings remove assembly seams that cause friction, simplifying manufacturing while maintaining smooth linear motion.
