Luoyang Newbee Transmission Secures Contract for Key Component of Large Indian Equipment, 3.5m Four-Point Contact Ball Slewing Bearing Showcases Core Strength

Luoyang Newbee Transmission Technology Co., Ltd. (hereinafter referred to as "Luoyang Newbee Transmission") has successfully signed a cooperation agreement with a renowned Indian machinery equipment manufacturer, leveraging its leading slewing bearing design and manufacturing capabilities. The company will supply the core component—a 3.5-meter diameter four-point contact ball slewing bearing—for the customer's heavy-duty equipment. This collaboration signifies a major breakthrough for Luoyang Newbee Transmission in expanding its international market for large-scale, high-precision slewing bearings, with its product technology strength once again winning favor from overseas high-end customers.

The 3.5-meter four-point contact ball slewing bearing supplied in this project embodies Luoyang Newbee Transmission's technological advantages. The product features a classic and efficient single-row ball four-point contact design. Through precisely calculated 45° contact angles, a single ball can simultaneously withstand combined loads from axial forces, radial forces, and overturning moments. This design ensures ultra-high load capacity and excellent anti-overturning stability while achieving a highly compact structure, perfectly meeting the dual requirements of the customer's equipment for space utilization and load-bearing performance.

"The core advantage of this large slewing bearing customized for our Indian customer lies in its exceptional comprehensive performance and reliability," stated the Technical Director of Luoyang Newbee Transmission when discussing the project. "The product utilizes high-quality, high-purity 42CrMo forged blanks. Key raceways undergo deep induction hardening treatment, ensuring surface hardness reaches HRC 55-60 while maintaining good core toughness, significantly enhancing wear resistance and fatigue life. Strict preload assembly processes guarantee smooth operation, high rigidity, and low noise. Furthermore, tailored for India's demanding operating conditions, we designed a multi-seal protection system (with optional NBR or FKM seal strips) to effectively isolate external dust and contaminants, keeping internal lubricant clean for extended periods, markedly prolonging maintenance cycles and service life."

This Indian customer, long dedicated to the R&D and manufacturing of large-scale equipment, imposes extremely stringent requirements on the precision, durability, and low failure rate of slewing bearings. Luoyang Newbee Transmission conducted an in-depth analysis of the customer's actual operating conditions, load spectrum, and spatial constraints, providing a complete customized solution encompassing selection calculations, structural optimization, and material processing. Ultimately, the company won the customer's trust and order through its robust technical proposal, reliable quality commitment, and efficient service response. This 3.5-meter slewing bearing will be applied to the slewing platform of the customer's new generation of large mining excavators, serving as a critical guarantee for the equipment's efficient and reliable operation.

Luoyang Newbee Transmission Technology Co., Ltd. has deep expertise in the slewing bearing field for many years, possessing a complete industrial chain—from raw material procurement, forging, heat treatment, precision machining to finished product assembly and testing—and a stringent quality control system. Equipped with high-precision machinery such as large CNC vertical lathes, large CNC gear hobbing machines, medium-frequency quenching equipment, and coordinate measuring machines (CMM), the company possesses batch manufacturing capabilities for large-diameter, high-precision, high-load capacity slewing bearings. The successful delivery of this 3.5-meter product to the Indian customer once again validates the company's technological heritage and process assurance capabilities in the large slewing bearing manufacturing sector.

"This cooperation with the Indian customer is a significant step in Luoyang Newbee Transmission's internationalization strategy," stated the company's General Manager. "We will seize this opportunity to continuously increase R&D investment, optimize production processes, and enhance product performance and service quality. We look forward to providing high-performance, reliable operation, and long-lasting slewing bearing solutions—including full series products like single-row ball, crossed roller, and three-row roller types—for more global customers in sectors such as construction machinery, mining equipment, port machinery, and wind power equipment, helping clients improve equipment competitiveness and create shared value."
