FZH, FZL, FZP ball retainer are as copper, aluminium, POM base. They are machined some regular and embedded the steel-ball into. The new work-craft will prevent the ball getting out of as old, as the ball diameter is larger than the retainer sthickness, so it will face to face directly with 90° guide bushing, that will bring high precision match now the ball retainer series items are designed to rotata on the post, as well as maintainits vertical motion, we believe this will give you the benefit of increasing accijracy.
Material Structure
Aluminium Base, Steel-ball Embedded
Advantage And Use
As the traditional work-craft has some grudga between bushing with posts, and the coefficvient of friction is larger, now we have changed the work-ways to steel-ball directiy face to face guide bushing, so the precision is improved, it composes of both active roll and lower friction coefficient, now they have been widely used in punching machine, die machine, high precision machine which need rotation and vertical motion.

Our FZH, FZL, and FZP series ball retainer bearings are expertly manufactured using high-grade aluminum, offering an ideal combination of light weight, strength, and corrosion resistance. Each retainer is carefully machined and designed to securely hold steel balls in place, ensuring smooth, reliable operation. The innovative design features a ball diameter slightly larger than the retainer thickness, which allows direct contact with the 90° guide bushing. This prevents balls from slipping out while maintaining precise alignment, resulting in exceptional accuracy for demanding applications.
The aluminum-based retainers are engineered to rotate freely around the post while simultaneously supporting vertical motion, providing dual-axis functionality. This ensures minimal friction, reduced wear, and stable performance under continuous or heavy-duty operation. The lightweight nature of aluminum also contributes to improved efficiency, reducing the overall load on mechanical systems.
Ideal for automation systems, precision machinery, and specialized mechanical equipment, these ball retainers enhance performance by combining smooth rotational movement with vertical stability. With their innovative construction, durable materials, and precise engineering, the FZH, FZL, and FZP aluminum-based ball retainer bearings deliver long-lasting reliability, high precision, and reduced maintenance, making them a trusted choice for engineers and designers seeking superior mechanical performance.
