Market Analysis of Constant-Section Thin-Walled Bearings By Luoyang BOBI Precision Bearing Co., Ltd.

Constant-section thin-walled bearings (also known as thin-section bearings) break through the limitations of traditional designs with their uniformly ultra-thin structure, striking an ideal balance between lightweight performance and high load capacity in precision sectors like semiconductors and robotics. Backed by 16 years of technical expertise, Luoyang BOBI Precision Bearing Co., Ltd.—under its proprietary brand NERT—has developed a comprehensive product portfolio spanning bore diameters up to 40 inches, delivering tailored solutions that excel in extreme operating conditions.

As high-end equipment manufacturing accelerates toward greater precision and intelligence, constant-section thin-walled bearings are increasingly emerging as a key growth driver in the core components market for rotating machinery, thanks to their unique performance advantages. As one of the earliest specialized manufacturers in this field, Luoyang BOBI Precision Bearing Co., Ltd. has drawn significant attention for its market performance and technological prowess.

Since its founding in 2010, Luoyang BOBI Precision Bearing Co., Ltd. has focused on the R&D and production of constant-section thin-walled bearings—at a time when most domestic applications still depended on products from KAYDON, an American bearing manufacturer. These bearings owe their popularity to their simplified structural profile, compact size, lightweight design, and space-efficient configuration, which align seamlessly with the demands of modern high-end intelligent equipment. They also effectively resolve the dimensional and weight constraints inherent in traditional bearings, shafts, and housings.

The company’s product line includes 7 open-type and 5 sealed variants, with bore diameters ranging from 1 to 40 inches and cross-sectional dimensions from 0.1875 to 1 inch. It covers three core categories: angular contact ball bearings, deep groove ball bearings, and four-point contact ball bearings. Each category is offered in multiple series, with over 10 inner-diameter options per series—creating a comprehensive product matrix that serves as a major competitive edge in the market.

A constant-section thin-walled bearing is a precision component defined by its ultra-thin cross-section, where the cross-sectional dimension remains consistent across a given series regardless of increasing bore diameter. This sets it apart sharply from conventional bearings and unlocks unique benefits in space-constrained, lightweight applications.

This structural design delivers several technical advantages:

These features make thin-walled ball bearings indispensable in space- and weight-sensitive applications, such as aerospace systems, robotic joints, and medical imaging equipment.

To address the needs of non-standard equipment and specialized operating conditions, the company provides tailored thin-walled bearing solutions. By optimizing raceway curvature, cage design, and material formulations, these solutions meet the demands of extreme environments—including high temperatures, vacuum conditions, and highly corrosive atmospheres. This flexible manufacturing capability creates distinct advantages in niche markets.

The company has implemented a full-process quality control system covering R&D, production, and inspection to ensure compliance with ISO standards and relevant industry regulations. Every stage—from raw material selection to finished product testing—is subject to rigorous monitoring. This unwavering commitment to quality has solidified the brand’s strong reputation in the marketplace.

Today, fueled by ongoing advancements in smart manufacturing and precision equipment, demand for constant-section thin-walled bearings continues to grow steadily. Leveraging its technological innovation capabilities, extensive product portfolio, and reliable quality assurance, Luoyang BOBI Precision Bearing is steadily expanding into the global high-end bearing market. Looking ahead, with the adoption of new materials and breakthroughs in manufacturing processes, the company is well-positioned to penetrate the civil aerospace sector further.
