Ningbo, Zhejiang, China – June 18, 2026 – Ningbo Bolin Bearing Co., Ltd. (BML), a leading designer, manufacturer, and service provider of miniature and special bearings, today announced its latest strategic developments and technological advancements. With a history dating back to the establishment of its predecessor, Ningbo Yonghui Bearing, in 2005, the company has evolved into a national high-tech enterprise renowned for its precision engineering, innovative R&D capabilities, and robust quality management systems. As BML continues to execute its "Second Venture" strategy, it is solidifying its position as a premier professional service provider for micro and special bearings.
Strategic Milestones and Manufacturing Scale
Since its founding in 2005, BML has undergone significant expansion to meet the growing global demand for high-precision components. The company's journey began in a 500-square-meter facility and has culminated in the establishment of a modern 12,000-square-meter manufacturing base on Xingyong Road, acquired in 2022. This strategic growth has enabled BML to achieve an annual production capacity of 300 million bearings.
Looking ahead, BML has outlined an ambitious investment plan totaling 120 million RMB to further enhance its production capabilities. The company aims to deploy 80 automated production lines within four years, targeting an annual output of 250 million bearings. This expansion is designed to support BML's strategic goal of capturing a 10% share of the domestic market for ultra-miniature bearings within five years. The company is actively building a "Q-SHEET Green Factory," integrating lean, automated, and digitalized production methods to ensure sustainable growth.
Comprehensive Product Portfolio and Customization Capabilities
BML offers a diverse range of high-precision bearings tailored to meet the exacting requirements of various high-tech industries. The company's core product lines include:
Miniature Deep Groove Ball Bearings: Available in metric series (e.g., 693, 624, 625), flange series (e.g., F688), MR series (e.g., MR95), and stainless steel series (e.g., S624). These bearings are engineered for high-speed applications, with some models capable of operating at speeds up to 120,000 rpm.
Angular Contact Ball Bearings: Featuring contact angles of 15°, 25°, and 30°, these bearings are available in duplex configurations (DB, DF, DT) to support complex axial and radial loads. BML also offers specialized ceramic ball angular contact bearings.
Needle Roller Bearings and Specialized Bearings: Including HK and K series needle roller bearings, as well as customized solutions such as double-groove ball bearings, full-ball bearings, and insert bearings.
A key differentiator for BML is its robust customization and collaborative development capability. The company maintains an independent equipment development and product design team, allowing it to work closely with clients to create "exclusive bearings" tailored to unique operating conditions and spatial constraints. This includes the ability to customize ring and ball materials, such as producing bearings that can withstand 1,000 hours of neutral salt spray testing for superior corrosion resistance.
Unwavering Commitment to Quality and Innovation
Quality and reliability are foundational to BML's corporate philosophy. The company adheres to a strict quality policy of "consistency and reliability," underpinned by the "Three Zhen" principle: Zhen Zuo (True Execution), Zhen Cha (True Inspection), and Zhen Gai (True Improvement). BML has obtained several authoritative certifications, including IATF 16949:2016 (for automotive quality management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health and Safety). Furthermore, the company has been recognized as a National High-Tech Enterprise, validating its commitment to technological innovation.
BML's dedication to R&D is evident in its investment in advanced monitoring and measuring systems. The company utilizes state-of-the-art equipment such as HALT (Highly Accelerated Life Testing) and ALT (Accelerated Life Testing) machines capable of testing bearings at speeds up to 150,000 rpm and temperatures up to 150°C. This rigorous testing regime ensures that BML's products deliver exceptional rotational accuracy, operational stability, and longevity even in the most demanding environments, such as high-speed motors and precision medical instruments.
Customer-Centric Philosophy and Global Partnerships
BML operates under the mission of "becoming a professional service provider for micro and special bearings." The company serves a broad spectrum of industries, including micro motors, automotive parts, textile machinery, automation equipment, robots, medical devices, and precision instruments. By focusing on the five core industries of HB motors, financial equipment, textile machinery, shaded pole motors, and small appliances, BML has established itself as a reliable OEM/ODM partner.
The company's customer-centric approach is supported by a comprehensive service system that integrates design, production, quality control, and after-sales support. BML's strategic partnerships with leading enterprises such as Leadpeace ICT (Luxshare Precision), ZLZyk (Moons'), Keli (KELI), and Jinzhong Co., Ltd., underscore its reputation for delivering high-quality, reliable solutions that meet international standards.
