Bearing Steel Flanged Bearings Manufacturers

As a Bearing Steel Flanged Bearings manufacturer, we at Jiangsu Yinghong Transmission Technology Co., Ltd. (YHU) produce precision flanged ball bearings that combine a deep groove ball bearing with an integral flange on the outer ring. This design allows direct bolt-on mounting to machine frames, eliminating the need for separate housings and reducing assembly time. Our range covers metric miniature, metric MF, inch FR, and thin-wall series, all manufactured from high-carbon chromium bearing steel for durability and consistent performance.

Our Bearing Steel Flanged Bearing Range

We offer four sub-series to match different bore sizes, load requirements, and mounting constraints. Each series is available with open, shielded, or sealed configurations, and we can customize flange dimensions to fit your specific bolt pattern.

All series are manufactured from GCr15 bearing steel (equivalent to AISI 52100) with hardness HRC 60–65. We control raceway geometry and surface finish to achieve low noise and low vibration, meeting ABEC-1 to ABEC-5 precision classes.

Application Fit

Flanged bearings are ideal where space is limited and a separate housing is impractical. The integral flange provides a precise mounting face and simplifies alignment. Our bearing steel flanged bearings are used in:

• Electric motors and micro motors
• Power tools and pneumatic tools
• Robotics and automation systems
• Drones and unmanned vehicles
• Medical devices and dental handpieces
• Semiconductor manufacturing equipment
• Textile machinery and printing presses

For corrosive environments, we also offer stainless steel flanged bearings, but the category focuses on our bearing steel line, which provides the best load capacity and fatigue life for general industrial use.

Engineering and Quality

Our factory in China operates with Japanese precision manufacturing technology and automated production lines. We perform 100% inspection on critical dimensions and random noise/vibration testing on finished bearings. Our quality management system is certified to IATF 16949, and our products comply with RoHS and CE requirements.

We control raw material sourcing, heat treatment, grinding, and assembly in-house. This vertical integration ensures consistent hardness, raceway geometry, and internal clearance. We also offer custom preload and clearance options for high-speed or high-load applications.

Configuration and Customization

We understand that standard catalogs do not cover every mounting requirement. Our engineering team can modify flange diameter, thickness, hole count, and hole spacing to match your existing bolt pattern. We also offer:

• Custom bore sizes and tolerances (H7, K6, etc.)
• Seals and shields: RS, 2RS, ZZ, Teflon, or custom
• Lubrication: grease type, fill quantity, or oil for high-speed
• Special cage materials (steel, brass, polymer)
• Non-standard widths or extended inner rings

We provide OEM/ODM services, from prototype to mass production, with full documentation and traceability.

Integration and Installation

Flanged bearings are designed for direct bolt-on mounting. We supply the flange hole pattern and recommend torque values for the mounting screws. The bearing bore is typically press-fit onto a shaft, while the flange is bolted to a wall or frame. Our technical team can provide installation drawings and tolerance recommendations to ensure proper fit and alignment.

For automated assembly lines, we can package bearings in tubes or trays with orientation to facilitate robotic handling. We also support kitting with other components if required.

Maintenance and Support

Bearing steel flanged bearings are designed for long service life with minimal maintenance. We provide technical support for installation, lubrication, and troubleshooting. Our failure analysis service helps identify root causes of premature bearing failure, such as misalignment, overloading, or contamination, and we recommend corrective actions.

We stock common sizes for quick delivery and offer scheduled production for large-volume orders. Spare parts and replacement bearings are available for the life of your equipment.

Information We Use to Configure Your Solution

To prepare an accurate quotation and engineering proposal, please provide the following details:

• Bore diameter, outer diameter, and width (metric or inch)
• Flange diameter, thickness, and mounting hole pattern
• Operating speed (RPM) and load (radial/axial)
• Temperature range and environmental conditions (dust, moisture, chemicals)
• Required precision class (ABEC-1, ABEC-3, ABEC-5)
• Sealing preference (open, shielded, sealed)
• Lubrication type and quantity
• Annual quantity and target delivery schedule

If you have a drawing or sample, send it to us and we will match or improve the specifications. Our engineers will confirm feasibility and provide a detailed technical datasheet.

Frequently Asked Questions

What is the difference between metric miniature F-Series and MF-Series?

Metric Miniature F-Series covers bores from 1 to 8 mm with a square flange, while MF-Series covers 10 to 12 mm bores with a round flange. MF-Series also has a larger outer diameter and is designed for slightly higher load capacities.

Can you customize the flange hole spacing?

Yes, we can modify the flange hole pattern to match your existing mounting holes. Provide the hole diameter, bolt circle diameter, and number of holes, and we will adjust the tooling accordingly.

What precision grade do you offer for bearing steel flanged bearings?

We manufacture to ABEC-1, ABEC-3, and ABEC-5 precision classes. For high-speed applications, we recommend ABEC-5 with tighter radial clearance and lower vibration limits.

Do you provide samples before mass production?

Yes, we can produce prototypes for your evaluation. Sample lead time is typically 15–20 days, and mass production begins after approval. We also provide test reports for noise, vibration, and dimensional accuracy.

What is the minimum order quantity?

For standard sizes, MOQ is 500 pieces. For custom designs, MOQ is 1,000 pieces. We can discuss lower quantities for initial validation or higher-volume pricing for annual contracts.
