Hengguan Bearings Professionally Assists Well-known Domestic Industrial Furnace Projects, Winning Customer Trust with Technical Strength

In May 2026, Luoyang Hengguan Bearing Technology Co., Ltd. received a procurement request from a well-known domestic industrial furnace manufacturer. The client, undertaking a rotary hearth furnace project, urgently needed a batch of high-performance Slewing Bearings. At this time, the project was still in the design phase, and the client hoped to receive technical support from Hengguan Bearings in selection and design.

Rotary Hearth Furnace (RHF) Definition: A special structural form of industrial furnace. Its furnace bottom (hearth) is rotatable, like a huge "ring-shaped turntable." Material is placed on the turntable and, as the turntable slowly rotates, passes through the charging zone, heating zone, soaking zone, and discharging zone in sequence. This furnace has rotational motion, off-center loading, a large diameter, and heavy loads. This unique operating condition determines that its requirements for slewing bearings are extremely stringent.

Upon receiving the request, the Hengguan Bearings technical team quickly connected with the client. After nearly a month of repeated communication, solution demonstration, and data verification, the Hengguan team, from a professional perspective and with a full understanding of the customer's operating conditions, ultimately recommended the slewing bearing model 011.60.2000.

In fact, the customer initially expected a diameter range of 3500-4000mm, but Hengguan Bearings, based on actual load, overturning moment, torque, and operating temperature data, and after rigorous calculations, determined that the smaller 2000mm series products were sufficient to meet the requirements. This adjustment not only significantly reduced the customer's procurement costs but also further improved the product's cost-effectiveness, truly reflecting Hengguan Bearings' service philosophy of "customer-centric and professionally oriented."

The customer's operating conditions were quite complex: the rotary hearth furnace turntable diameter was 5650mm, the total weight of the steel structure plus the load was 50t, with an off-center load of 12t, the maximum operating temperature reaching 150℃, the operating temperature around 100℃, and the site was dusty. Faced with these conditions, Hengguan Bearings equipped its products with a dustproof solution using Gears and steel dust covers, ensuring stable and reliable operation of the slewing bearings under high temperature, heavy load, and dusty conditions.

Throughout the product design, drafting, manufacturing, and delivery processes, Hengguan Bearings strictly controlled quality to ensure that every step met the customer's technical requirements. On August 28, 2026, the customer's 4.5-meter rotary hearth furnace project was successfully installed, commissioned, and delivered to the user's site for operation. Throughout the process, Hengguan Bearings' professional technical capabilities, rigorous work attitude, and comprehensive service awareness deeply impressed the customer.

From initial technical support to full follow-up after product delivery, Hengguan Bearings always prioritizes customer needs, fulfilling its promise of "one-time cooperation, lifelong friendship" with concrete actions. In the future, Hengguan Bearings will continue to deepen its expertise in the slewing bearing field, providing more professional products and services to help more customers achieve project success.
