61800 Series
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.
