Flanged Bearings Manufacturer – Precision Mounting, Simplified

Jiangsu Yinghong Transmission Technology Co., Ltd. manufactures flanged bearings under the registered YHU brand. As a Flanged Bearings manufacturer, we combine a machined flange with a deep groove ball bearing to give you a ready-to-bolt bearing unit that controls axial location and simplifies housing design. Our range covers bearing steel and stainless steel variants, in metric, inch, and thin-wall series, for applications from miniature instruments to industrial automation.

We operate automated production lines with Japanese precision manufacturing technology, and every unit is tested for noise, vibration, and dimensional accuracy before shipment. Whether you need a standard series or a custom flange pattern, we configure the bearing to your shaft, load, and environmental requirements.

Our Flanged Bearing Range

We supply two main material families, each with multiple series to match your application and mounting constraints.

Application Fit and Engineering Value

Flanged bearings eliminate the need for a separate housing and locking nut. The flange plate is drilled with mounting holes so you can bolt the unit directly to a machine wall, frame, or bracket. This reduces assembly time, saves axial space, and provides positive axial location in both directions.

Typical applications include:

• Electric motors and gearboxes – where precise shaft location is required
• Power tools and pneumatic tools – compact, high-speed operation
• Robotics and drones – lightweight, low-friction units
• Medical devices and dental handpieces – stainless steel for hygiene and corrosion resistance
• Semiconductor and precision instruments – low noise and vibration
• Marine and chemical equipment – SUS316 for saltwater and aggressive media

We also support custom flange patterns, bolt hole positions, and shaft locking methods. If you have a drawing or a sample, we can match or optimize the design.

Critical Specifications and Performance

Our flanged bearings are manufactured to ISO, North American, and JIS standards where applicable. We control the following parameters to ensure reliable operation:

Configuration and Customization

We understand that standard catalogs do not always cover your exact requirement. Our engineering team can modify flange dimensions, bolt hole patterns, material grade, and internal clearance. We also offer custom non-standard flanged bearings for OEM projects.

Common customization options include:

• Non-standard bore sizes and tolerances
• Special flange shapes (square, oval, or custom)
• Additional mounting holes or counterbores
• Hybrid designs with ceramic balls for higher speed or insulation
• Special lubricants for food-grade, vacuum, or high-temperature service

We provide prototype development and mass production, with full documentation of the final configuration.

Quality Assurance and Acceptance

Our factory operates a closed-loop quality management system covering raw material inspection, in-process checks, and final testing. We use high-precision instruments to verify dimensions, noise, vibration, and sealing performance. Our certifications include IATF 16949, RoHS, CE, and SGS, which support automotive, medical, and export applications.

For each batch, we can provide inspection reports, material certificates, and dimensional data. If your project requires third-party testing, we coordinate with SGS or other accredited labs.

Installation, Maintenance, and Service

Flanged bearings are designed for simple bolt-on installation. We supply units with pre-filled grease and sealed options, so no additional lubrication is needed before mounting. For maintenance, regular inspection of bolt torque and seal condition is sufficient in most applications. We offer spare parts and technical support for the life of the product.

Our team can also provide installation guidelines, torque specifications, and troubleshooting advice based on your operating conditions.

Information We Use to Configure Your Solution

To prepare an accurate quotation and technical proposal, we need the following details:

• Shaft diameter and tolerance (metric or inch)
• Flange outer diameter and mounting hole pattern (or a drawing)
• Material preference: bearing steel or stainless steel grade
• Operating load (radial and axial) and speed
• Environmental conditions: temperature, humidity, chemicals, washdown
• Required sealing and lubrication
• Expected quantity and delivery schedule

Send us your drawing or sample, and we will confirm the exact configuration, tolerances, and testing requirements.

Frequently Asked Questions

What is the difference between bearing steel and stainless steel flanged bearings?

Bearing steel (GCr15) offers higher hardness and load capacity, while stainless steel provides corrosion resistance. Choose stainless for washdown, marine, or chemical environments; use bearing steel for general industrial applications where cost is a factor.

Can you match an existing flanged bearing from another brand?

Yes. We can reverse-engineer from a sample or drawing. We will confirm dimensions, material, and performance to ensure interchangeability.

What is the typical lead time for custom flanged bearings?

Prototypes can be delivered in 2–3 weeks after drawing approval. Mass production lead time depends on quantity and material availability, typically 3–5 weeks.

Do you provide test reports with each shipment?

Yes. We provide dimensional inspection reports and can include noise, vibration, and material certificates upon request. Third-party SGS testing is also available.

Can you supply flanged bearings with ceramic balls?

We can produce hybrid flanged bearings with ceramic balls for higher speed, electrical insulation, or reduced friction. Discuss your requirements with our engineering team.
