As a professional Wholesale Thin-Wall F-Series Factory, Jiangsu Yinghong Transmission Technology Co., Ltd. (YHU) manufactures a complete range of thin-wall flanged bearings in bearing steel. Our F67, F68, and F69 series are designed for applications where axial space is limited and precise radial location is required. These bearings combine a thin cross-section with an integral flange on the outer ring, allowing direct mounting into housings or plates without additional retaining rings.
We produce these bearings using Japanese precision manufacturing technology and fully automated production lines, ensuring consistent geometry, low noise, and long service life. Our factory covers over 15,000 square meters and is equipped with 300+ sets of production equipment, backed by a dedicated team of 200+ employees. We hold IATF 16949, RoHS, CE, and SGS certifications, confirming our commitment to quality and environmental compliance.
The Thin-Wall F-Series is part of our Bearing Steel Flanged Bearings category. We offer three primary series, each tailored to different bore size and load requirements:
| Series | Characteristics | Typical Applications |
|---|---|---|
| F67 Series | Extra-thin wall, smallest cross-section, ideal for ultra-compact designs | Miniature motors, encoders, small pulleys |
| F68 Series | Balanced thin wall and load capacity, most popular for general instrumentation | Robotics, drones, medical devices |
| F69 Series | Slightly thicker wall, higher load rating, still compact | Power tools, gearboxes, semiconductor equipment |
All series are available in open, shielded (ZZ), and sealed (2RS) configurations. We also offer custom bore sizes, flange dimensions, and preload options to match your specific housing design.
Thin-wall flanged bearings excel in applications where axial space is at a premium and the bearing must be located positively without complex housing features. The integral flange eliminates the need for separate snap rings or shoulders, simplifying assembly and reducing part count. Our F-Series bearings are engineered for low friction and low vibration, making them suitable for high-speed rotation and precision instruments.
We serve industries such as electric motors, power tools, pneumatic tools, robotics, drones, household appliances, precision instruments, semiconductor equipment, medical devices, and aerospace. The bearing steel construction provides high hardness and wear resistance, while our heat treatment and grinding processes ensure dimensional accuracy and consistent running torque.
Our production process follows Japanese precision manufacturing standards, with automated grinding, honing, and assembly lines. Each bearing undergoes rigorous inspection using high-precision testing equipment. We verify radial clearance, bore and outer diameter tolerances, flange squareness, and noise levels. Our quality management system is certified to IATF 16949, and we also comply with RoHS and CE directives. SGS test reports are available for material and performance verification.
We maintain a closed-loop quality system from raw material incoming inspection to final packaging. Every batch is traceable, and we provide inspection certificates with shipments upon request.
Beyond standard F67/F68/F69 sizes, we offer extensive customization to meet your exact requirements. Our engineering team can modify:
We also support OEM/ODM projects, from prototype to mass production. If you have a drawing or sample, we can reverse-engineer and produce a matching bearing with full documentation.

With this information, we can recommend the optimal configuration and provide a detailed specification sheet for your approval before production.
The main difference is the wall thickness and load capacity. F67 has the thinnest wall, ideal for ultra-compact designs. F68 offers a balance between size and strength, while F69 has a thicker wall for higher loads. We can help you select the right series based on your shaft diameter and load requirements.
Yes, we specialize in custom bearings. We can modify flange diameter, thickness, and even the number of mounting holes if needed. Send us your drawing or specify the required dimensions, and we will produce a prototype for validation.
Standard Thin-Wall F-Series bearings use chrome steel (GCr15) for both rings and balls. For higher corrosion resistance or non-magnetic applications, we can supply stainless steel (440C, 304, 316) or hybrid ceramic balls. We also offer plastic cages for reduced weight and noise.
Yes, we provide material certificates, dimensional inspection reports, and noise/vibration test data with each batch. Our factory is IATF 16949 certified, and we can issue SGS test reports for specific performance criteria upon request.
For standard sizes, we usually ship within 15–20 days. Custom orders require additional time for tooling and prototyping, typically 30–45 days depending on complexity. We will confirm the exact lead time when you submit your inquiry.
Our portfolio also includes Products, Deep Groove Ball Bearings for applications with different operating ranges, interfaces or integration requirements.
