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).

Product Description
Technical Specifications
Product Details
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.
