Metric Miniature F-Series Manufacturers

Jiangsu Yinghong Transmission Technology Co., Ltd. (YHU) is a professional manufacturer of high-precision deep groove ball bearings and customized non-standard bearings. Our Metric Miniature F-Series is the flanged branch of our metric miniature bearing programme: a compact radial ball bearing with an integral flange on the outer ring, so the bearing can be located axially without separate retaining hardware. As a wholesale Metric Miniature F-Series Factory, we produce the F60, F62, F63, F68 and F69 series for customers in precision instruments, small motors, robotics and automation equipment.

Product Range and Positioning

The Metric Miniature F-Series belongs to our Bearing Steel Flanged Bearings group and is available in the five dimensional families shown below. The flange diameter, bore size, width and ball complement follow metric miniature bearing conventions; we quote exact dimensions from our catalogue or from your drawing.

Application Fit and Mounting

The outer flange replaces a shoulder, circlip or housing cover. This allows the bearing to be pressed into a plain through-bore while the flange locates the axial position, simplifying housing machining and speeding assembly. The flange also gives better axial support in applications where the bearing is mounted in thin sheet-metal housings.

For installation, we recommend a controlled press-fit on the stationary ring and a light push fit on the rotating ring, with grease fill and seal type selected for the operating speed and ambient condition. Bearing tolerances, radial internal clearance and preload are defined in our proposal so your assembly team knows what to expect before the first pilot run.

Material and Performance Characteristics

• Bearing steel rings and balls, hardened for rolling contact fatigue
• Open, shielded or sealed configurations according to environment
• Low noise and low vibration for quiet-running miniature equipment
• Grease or oil lubrication selected for speed, temperature and torque requirements
• Interchangeable with common metric miniature flanged bearing sizes

Engineering and Customization Support

As a National High-Tech Enterprise, we hold IATF 16949, RoHS, CE and SGS certification and use automated production lines with high-precision testing equipment. Our engineering team supports bearing design and optimization, prototype production, mass delivery and failure analysis. Customization options include bore and flange geometry, width, seal type, cage material, ball grade and lubrication. For non-standard designs we work from drawings, samples or a failed part to be reverse-engineered.

This range sits inside our wider Flanged Bearings programme. Depending on your project, we can also propose a stainless steel flanged bearing from our corrosion-resistant families or a thin-wall F-series variant for weight-sensitive assemblies.

Quality Assurance and Acceptance Testing

Each production batch is controlled from incoming steel to final assembly. We verify key dimensions, radial internal clearance, running accuracy, noise, vibration, sealing and grease behaviour before release. SGS test reports are available for the F-series range, and our quality system follows IATF 16949 procedures for production part approval and traceability.

Information We Use to Configure Your Solution

Provide the following information with your enquiry. We use it to prepare the bearing configuration, inspection plan and quotation for your specific project.

• Application and operating environment: load, speed, temperature, humidity or corrosive media
• Mounting details: shaft and housing dimensions, tolerances, fit and expected deflection
• Performance targets: noise, vibration, friction torque and working life
• Required configuration: F60, F62, F63, F68 or F69, open/shielded/sealed, lubrication
• Quantity, delivery schedule and packaging requirements
• Drawings, samples or failed bearings for custom development

Frequently Asked Questions

What is the difference between Metric Miniature F-Series and Metric MF-Series?

Metric Miniature F-Series covers flanged versions of the F60, F62, F63, F68 and F69 metric miniature deep groove families. Metric MF-Series is a separate flanged range with a different cross-section and bore combination. If you cannot find your exact size, send the dimensions; we will match it to the correct series or produce a custom flange bearing.

Can flange dimensions, bore size or width be customized?

Yes. We produce custom non-standard bearings alongside standard lines. We can adjust bore, outer diameter, flange diameter, thickness, chamfers and ball complement. Send a drawing or sample, and we will confirm feasibility before quoting.

Are these bearing steel F-Series bearings suitable for medical or dental applications?

Many customers use the same compact geometry for medical devices, dental handpieces and laboratory instruments. For those environments we can supply stainless steel flanged bearings and specialized lubricants. Confirm speed, sterilization and corrosion requirements in your enquiry so we can propose the correct material and seal package.

What quality documentation is available?

We are certified to IATF 16949, RoHS, CE and SGS, and we can provide dimensional reports, material certificates, SGS test reports and, for serial production, a control plan. Specific documentation requirements can be written into the quotation.

How can we order a small quantity for testing before mass production?

Send your application conditions and target quantity. We can supply prototype samples first and then scale to serial production after sample approval. Our engineering team remains available during your pilot assembly and field trials.
