A link ball that achieves smooth operation with minimal play.
The link ball uses high-precision bearing steel balls in the spherical part, and after forming the holder by die-casting, the shank part is specially welded. This innovative manufacturing method allows the mirror surface of the steel ball to be transferred to the spherical part of the holder, resulting in full surface contact and smooth operation with minimal clearance.

basic information
● Compact Design The BL type features an advanced balance design that maintains sufficient strength while achieving an extremely compact shape. It is ideal for applications such as automotive height sensor link components and transmission control parts. ● Sphericity of 0.001mm The spherical part of the ball-equipped shank directly reflects the sphericity of the bearing steel balls, achieving a smooth operation with a minimum clearance of less than 0.001mm, providing excellent operability and feel for link motion. ● Two Types of Holder Materials For the holder material, the BL-A type uses a newly developed high-strength aluminum alloy "A-1 alloy," which is lightweight and has excellent wear resistance. ● Excellent Lubrication Performance Products of the BL type, including those with boots, are sealed with grease, enhancing lubrication and improving wear resistance. ● Adoption of Large Hexagonal Seat The hexagonal dimensions of the shank are based on automotive standards, matching the size of small hex bolt seats, ensuring no seat deformation due to tightening and achieving a reliable link motion mechanism.
