Product Description

Thin-walled bearings are small, lightweight bearings with ultra-thin cross-sections. They are primarily available in seal types such as RS and ZZ. They are manufactured by manufacturers like Luoyang Preson. Their inner diameter to outer diameter ratio is ≤1.25, and they utilize a uniform cross-section design to maintain high precision and strong load-bearing capacity. They include thin-walled crossed roller bearings, deep groove ball bearings, and four-point contact ball bearings, achieving product precision levels of P4 and P2.

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. Bearings feature an extremely thin cross-section, enabling miniaturization and lightweighting. This diverse product range expands their applications.

In particular, the thin-walled 6900series,16000 series and 6800 series are available in a wide variety of styles, including dust cover, flanged, stainless steel, and wide-width models.
