Linear Bearings TRIZ Cases

Recesses and holding protrusions lock the guide block to the rail under external load, enabling a compact motion guide with smooth rolling.

Axial protrusions and a varying inner diameter cut bearing bush assembly force while limiting eccentricity and keeping out dirt and moisture.

An outboard guide bearing supports can bodymaker journals instead of the ram, cutting droop, wear, and fluid contamination.

A locally crowned low-pressure bush surface prevents blade edge contact, preserves the oil film, and reduces wear and seizing.

A plastic-sprayed coating on bearing retainers improves wear and corrosion resistance, cushions impact, and reduces operating noise.

A porous non-circular lubricating tube stores and releases oil through inner recesses to extend slide rail lubrication and cut maintenance.

A spring-biased slider and rolling element remove lead screw and guide clearances to suppress backlash in X, Y, and Z motion.

High-heat thermoplastic sleeves with grease-pool grooves keep linear motion guides lubricated and stable above 80°C.

A Bingham fluid pocket and sealing structure cut hydrostatic bearing leakage, lowering pump demand while tolerating gap variation.

An integrated Y-groove and return-channel layout speeds oil supply, improves uniform slider lubrication, and cuts leakage and parts.

A variable cone-angle air bearing combines negative and positive stiffness to isolate substrate vibrations while maintaining precise positioning.

A staggered two-row ball housing band increases motion guide precision and rigidity while keeping the circulation path compact and limiting carriage deformation.

A PTFE fabric with heat-stable polyimide resin keeps friction parts operating up to 300°C while maintaining low wear and load resistance.

Inclined contact surfaces and prestressing distribute slide loads more evenly, limiting pad wear, clearance growth, and guidance errors.

Odd spiral-thread recirculating tubes laterally flip rolling balls to spread load, prevent speed mismatch, and reduce guide noise.

Deformed sections in side-by-side wire springs let slide mechanisms change spring constant quickly without resizing the spring unit.

A tapered rolling-member clamper lets a movable block lock anywhere on the rail while reducing mechanism size and weight.

Built-in audible and visual wear sensing replaces shims in an adjustable wear pad, helping maintain clearance and schedule timely replacement.

A dual-gas air bearing uses a cover, wiper, and high-pressure nozzle to clear guideway particles and keep CMM measurements precise.

Axial slits and elastic-ring support let this steering slide bearing absorb reaction forces, avoid tube collisions, and suppress rattling noise.

Superhard support elements replace small support balls to resist point loading, spalling, corrosion, and debris buildup while preserving free rolling.

Magnetic attraction gaps hold the dustproof strip without contact, preventing friction dust in a linear module.

A voice coil deforms the bearing plate to tune air-gap shape, improving stiffness, load control, and compensation for geometric errors.

Rotatable actuators and clamps let screen-printing stencils self-correct X-Y planarity errors while staying fixed during printing.

A ball screw and helical bearing system replaces hydraulic actuation to drive rotatable aircraft components with more precise control.

Sliding contact pads add axial damping to existing rolling guides without extra size, helping seismic isolation absorb vibration early.

Laser-made microchannels on machine tool guide surfaces cut friction and wear, enabling faster linear motion with stable guidance.

Vibration and speed sensing on the moving member reveals rolling surface and lubrication state in real time, supporting timely lubricant supply.

Transverse drive-unit movement compensates steering column tolerances, avoiding constraint-induced noise, vibration, and spindle wear.

Adjustable discharge flow keeps the air film stable under varying loads, preserving stiffness and load support in a vacuum-preloaded air bearing.

Rotational X-Y planarity control and clamping correct stencil-to-workpiece angular errors and hold precise alignment during printing.

A dual blocking member holds a safe rail gap during retraction, preventing finger pinching until the user releases the operator.

Curved metal inserts and an elastic annular reinforcement help a resin linear bearing resist deformation, prevent housing slippage, and keep motion smooth.

Magnetic attraction gaps keep the dustproof strip from rubbing the slide seat, reducing particle generation while preserving sealing.

A screw-fastened dual-shell attachment adds sealed long-term rail lubrication to linear bearings while easing retrofit and preventing leakage.

Elastic balls in the circulation path replace spacers, easing rolling guide assembly while preventing friction spikes and operational failure.

Ni-Si precipitation-hardened copper alloy coatings improve engine sliding member wear resistance while reducing porosity and retaining heat conduction.

Measures motion guide loads from slider position and radial or horizontal displacement, improving in-use accuracy and service life prediction.

Sliding contact pads pressed against the track rail add axial damping to existing rolling guides without increasing size in seismic isolation use.

A laterally deflected belt section inside the carriage removes slack and maintains tension without adjustable pulley spacing.

A two-stage lubricant passage with an expanded hollow section routes grease around bolt holes, supporting common cover designs and stable rolling-member lubrication.

An integrated seal in the rolling element cage keeps grease contained and contaminants out, improving telescopic steering shaft reliability.

A deeper screw groove and smaller screw balls prevent misrouting at groove intersections while cutting ball screw spline size and weight.
