RA Series Crossed Roller Bearings Successfully Matched to Rotary Tables of Italian Filling Machines

Date: March 18, 2026

Customer:High-end enterprise in Italy's filling machine manufacturing industry

Background

Italy is a global core production base for high-end food, daily chemical and pharmaceutical packaging equipment. A well-known local manufacturer focuses on rotary high-precision automatic filling machines targeting high-end markets in Europe and North America, widely used for automated liquid filling of mineral water, juice, oral liquid, sauce and other materials. The central rotating table, as the core component of the equipment, is the key mechanism to realize multi-station filling and capping integration. It needs to withstand radial, axial combined loads and overturning moments for a long time, and meet the requirements of high-speed operation, precise indexing and zero-backlash rotation. Previously, the customer relied on imported European bearings for a long time, with high cost and long delivery cycles. To optimize the supply chain and improve product cost performance, the customer screened precision bearing suppliers worldwide, with core requirements: P4 ultra-high precision, ultra-thin compact structure, strong anti-overturning rigidity, food-grade clean working condition adaptation, and long-term zero-failure operation.

What Are RA Series Crossed Roller Bearings？

RA Series is a high-precision thin-section crossed roller bearing with an integrated inner ring and 90° crossed cylindrical rollers. It features compact structure, high rigidity and high rotation accuracy. All products can reach P4 precision grade, support radial, axial and moment loads at the same time, and are widely used in filling machines, rotary tables, packaging machinery and automated assembly equipment.
