HZK Thin-walled bearings cross-section design and hollow shaft technology reduce friction torque by reducing the diameter of the steel ball, achieving lightweight and miniaturization while improving rotational accuracy and rigidity. Products include a variety of structures such as dust cover, flange, stainless steel, and wide width. Typical models include the 6900 and 6800 series. They can withstand radial and axial loads and have a maximum speed of 6500 r/min (oil lubrication).
To achieve low friction torque, high rigidity, and excellent rotational accuracy, the bearings utilize small outer diameter steel balls. The use of a hollow shaft ensures lightweight design and space for wiring. Qian-type bearings feature an extremely thin cross-section, enabling miniaturization and lightweighting. This diverse product range expands their applications.
In particular, the thin-walled 6900 and 6800 series are available in a wide variety of styles, including dust cover, flanged, stainless steel, and wide-width models.
