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
POM 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.

The FZH, FZL, and FZP ball retainer bearings feature durable aluminum bases, combining lightweight design with strength and corrosion resistance. Each retainer is precisely machined to securely hold steel balls, ensuring smooth, reliable movement and long-lasting performance. Unlike traditional designs, the ball diameter is slightly larger than the retainer thickness, allowing direct contact with a 90° guide bushing. This innovative feature prevents balls from dislodging while maintaining exact alignment, delivering superior precision.
Designed to rotate around the post while supporting vertical motion, these ball retainers offer dual-axis functionality, reducing friction and wear even under continuous or heavy-duty operation. Aluminum’s low weight enhances efficiency by minimizing mechanical load, while maintaining stability and smooth operation.
Ideal for automation systems, precision machinery, and specialized equipment, the FZH, FZL, and FZP series improve accuracy and reliability in demanding applications. With advanced engineering and high-quality materials, these aluminum-based ball retainers provide consistent performance, reduced maintenance, and extended service life. Engineers and designers can rely on them for applications where precision, durability, and efficiency are critical, making them a dependable solution for modern mechanical systems.
