China's premier bearings
Where precision drives globalmotion!
Ball retainer bearings, such as the FZH, FZL, and FZP series, provide reliable, low-friction, and high-precision motion control for modern industrial machinery. Constructed from copper, aluminum, or POM bases with embedded steel balls, these bearings feature an innovative design in which the ball diameter exceeds the retainer thickness. This allows direct face-to-face contact with guide bushings, improving precision, reducing friction, and ensuring smooth rotational and vertical motion—outperforming traditional designs that often suffered from higher friction and clearance issues.
These bearings are particularly suited for applications requiring both rotational and vertical motion with high accuracy. They are widely used in punching machines, die-making equipment, and other precision machinery where consistent motion and dimensional accuracy are critical. By combining rolling motion with a low coefficient of friction, ball retainer bearings enhance operational efficiency, reduce wear, and extend the service life of guiding components.
