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
Copper 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 ball retainer bearings are crafted with high-quality copper, aluminum, or POM bases, engineered to provide exceptional performance in demanding mechanical applications. Each retainer is precisely machined to hold steel balls securely, ensuring smooth rotation and minimal play. Unlike traditional designs, the ball diameter is intentionally larger than the retainer thickness, which allows direct contact with the 90° guide bushing. This innovative design prevents balls from slipping out while maintaining optimal alignment, resulting in significantly improved precision.
The series is specifically designed to allow rotation around the post while preserving vertical movement, offering a dual-axis functionality that enhances stability and control. This careful engineering minimizes vibration and wear, extending the service life of the bearing and ensuring consistent performance under heavy loads. Ideal for applications requiring both rotational and linear motion, these ball retainers deliver high accuracy, smooth operation, and long-term durability.
Whether in automation equipment, precision machinery, or specialized mechanical systems, our copper-based ball retainer bearings provide reliable performance with reduced maintenance. By combining advanced materials, innovative design, and meticulous manufacturing, they represent a trusted choice for engineers seeking precision, efficiency, and longevity in their bearing solutions.
