More Industry knowledge

Shaoxing Shangyu Flight Seiko Machinery Co., Ltd. (FTM) specializes in manufacturing Cylindrical Roller Bearings Without Inner Ring, designed for applications where the shaft cannot serve as a raceway. This innovative bearing structure eliminates the inner ring, directly utilizing the hardened and ground shaft surface as the inner raceway, thereby achieving higher rotational accuracy and compact installation space optimization. Ideal for heavy radial loads and moderate axial loads, our bearings are widely used in robotics, precision machinery, textile equipment, and high-speed automation systems.

Key Advantages:
Precision Engineering: Leveraging over 30 years of technical expertise and guided by tribology PhDs, our bearings ensure exceptional dimensional stability and minimal friction .
Advanced Manufacturing: Equipped with Japanese CNC machine tools and ultra-precision grinding centers, FTM guarantees tolerances within IT4-IT5 grades and surface roughness ≤Ra 0.2μm, meeting stringent international standards .
Customization Flexibility: Tailored solutions for outer diameters (10–250mm), sealing structures (bakelite, nylon, or metal retainers), and multi-row assemblies (double/triple/quadruple) to adapt to diverse load conditions .
Quality Assurance: Certified under IATF16949, our bearings undergo rigorous testing, including chemical composition analysis, ultrasonic flaw detection, and heat treatment validation, ensuring durability even in extreme environments .
Global Recognition: Trusted by Fortune 500 clients like Boeing and Caterpillar, our products are exported to Germany, the U.S., India, and beyond, proving reliability in mission-critical industries.
