Precision lock & Nut

YSR

The YSR series lock nut is engineered for high axial load applications requiring exceptional locking strength and stability. Its robust structure ensures secure positioning of ball screws, spindles, or rotating shafts under dynamic conditions. Ideal for heavy-duty CNC, machine tools, and precision motion systems.

YSF

The YSF series features a flange design for improved stability and surface contact, ensuring enhanced axial retention and ease of mounting. Designed for high-speed applications, it offers precise clamping without loosening under vibration. Perfect for spindles, ball screws, and rotating assemblies.

YSA

The YSA series is a thin-profile precision lock nut, ideal for space-constrained applications. Despite its compact size, it delivers reliable locking performance with fine thread engagement and axial rigidity. Suited for compact motor shafts, linear modules, and high-precision automation.

YSK

The YSK series incorporates a slotted body design that allows for superior clamping force and thermal resistance. It provides consistent locking torque, ideal for applications exposed to variable loads or temperature shifts. Used widely in robotic arms, precision bearings, and spindle systems.

SWLE Precision Lock and Nut

The SWLE Precision Lock and Nut system ensures secure axial positioning of rotary components under high load conditions. Its serrated locking interface provides excellent resistance to vibration and loosening. Ideal for spindle systems, precision drives, and demanding motion control applications.

Shaft Locking Devices

Shaft Locking Devices are designed for backlash-free shaft-hub connections without the need for keyways. Their internal expansion principle ensures uniform surface pressure and high torque transmission. Widely used in pulleys, gears, and heavy-duty rotating assemblies.

Keyless Locking Assembly

Keyless Locking Assemblies provide a strong, friction-based shaft connection, eliminating the need for keyways or splines. They offer easy installation and removal with superior torque transmission. Perfect for applications requiring high concentricity and zero backlash, such as drives, motors, and gear systems.
