Stainless steel angular contact ball bearings have internal raceways that are effectively opposite each other, they are designed to accommodate both axial and radial loads and when used in pairs have a tremendous load bearing capacity.

A flange bearing is a housed bearing assembly in which the outer housing carries a machined flange plate drilled with mounting holes. The flange plate allows the unit to be bolted directly onto a mac...

View MoreJiangsu Yinghong Transmission Technology Co., Ltd. (YHU) is a professional Stainless Steel Angular Contact Ball Bearings manufacturer and supplier based in China. We produce a full range of stainless steel angular contact ball bearings engineered for combined radial and axial loads in corrosive, washdown, and hygienic environments. Our factory integrates Japanese precision manufacturing technology with automated production lines and high-precision testing equipment, ensuring consistent quality across every batch.
We offer five material families—SUS420, SUS440, SUS304, SUS316, and special stainless steels—each selected to match specific hardness, corrosion resistance, and magnetic requirements. Whether you need a standard 15° or 25° contact angle, a custom cage material, or a non-standard bore size, we configure the bearing around your working point and production target.
Martensitic stainless steel with good hardness and moderate corrosion resistance. Suitable for general industrial applications where load capacity and wear resistance matter more than extreme corrosion protection.
High-carbon martensitic grade offering maximum hardness and wear resistance. Ideal for high-load, high-speed spindles and precision instruments where dimensional stability is critical.
Austenitic, non-magnetic stainless steel with excellent corrosion resistance. Best for food processing, medical devices, and marine equipment where hygiene and non-magnetic properties are required.
Adds molybdenum for superior resistance to chlorides and aggressive chemicals. Recommended for offshore, chemical processing, and pharmaceutical applications.
Custom alloys, hybrid ceramic balls, or specialized heat treatment for extreme temperatures, vacuum, or high-speed operation. We develop these with your engineering team.
Angular contact ball bearings have raceways that are offset relative to each other, allowing them to support combined radial and axial loads in one direction. Stainless steel versions add corrosion resistance, making them the first choice for equipment that undergoes regular washdown, operates in humid or chemical environments, or must meet food-grade and medical standards.
Typical applications include:
We support OEM projects from prototype to mass production. Our engineering team can adjust contact angle, preload, cage type, and sealing arrangement to match your load spectrum, speed, and environmental constraints.
When we prepare a proposal, we evaluate the following parameters:
We also produce non-standard bore sizes, special chamfers, and custom markings. Our automated lines handle both small-batch prototypes and high-volume production runs.
| Material | Hardness (HRC) | Corrosion Resistance | Magnetic | Typical Applications |
|---|---|---|---|---|
| SUS420 | 48–52 | Good | Yes | General industrial, power tools |
| SUS440 | 58–60 | Good | Yes | High-speed spindles, precision instruments |
| SUS304 | ~20 (work-hardened) | Excellent | No | Food, medical, marine, cleanroom |
| SUS316 | ~20 (work-hardened) | Superior (chloride resistant) | No | Chemical, offshore, pharmaceutical |
| Special Alloys | Varies | Tailored | Varies | Extreme temperature, vacuum, high speed |
Our factory operates under a closed-loop quality management system covering raw material incoming inspection, in-process gauging, and finished product testing. We verify dimensional accuracy, running noise, vibration, sealing effectiveness, and corrosion resistance on every batch. As a National High-Tech Enterprise, we hold multiple patents and have achieved IATF 16949, RoHS, CE, and SGS certifications.
We also provide material certificates, inspection reports, and traceability documentation with each shipment. For critical applications, we can perform additional tests such as salt spray, temperature cycling, or axial play measurement.
To prepare an accurate quotation and technical proposal, we need the following project data:
With this information, we can recommend the optimal material, cage, seal, and internal geometry. We also provide samples for validation before mass production.
Stainless steel angular contact bearings are typically mounted with a press fit on the shaft and a slip fit in the housing, or vice versa depending on the rotating ring. We provide mounting recommendations and can supply matched sets with preload already set. For maintenance, our bearings are designed for long service life with proper lubrication; we offer relubrication intervals and grease specifications in the technical datasheet.
We stock spare parts for standard sizes and can arrange quick turnaround for custom replacements. Our after-sales team provides failure analysis and design optimization support if you encounter premature wear or noise issues.
In addition to stainless steel angular contact ball bearings, we manufacture Deep Groove Ball Bearings and Stainless Steel Bearings for applications that do not require axial load capacity. Our full Products range also includes flanged bearings, thrust bearings, ceramic bearings, and plastic bearings.
Q: What is the difference between SUS304 and SUS316 for angular contact bearings?
SUS316 contains molybdenum, which significantly improves resistance to chlorides and acidic environments. If your application involves seawater, bleach, or aggressive chemicals, SUS316 is the safer choice. SUS304 is non-magnetic and offers excellent general corrosion resistance at a lower cost.
Q: Can you produce non-standard bore sizes or custom contact angles?
Yes. We regularly manufacture non-standard bore diameters, special widths, and contact angles other than the standard 15° and 25°. Provide your drawing or specify the required geometry, and we will produce a prototype for validation.
Q: Do you offer hybrid ceramic ball versions of stainless steel angular contact bearings?
Absolutely. We can combine stainless steel rings with silicon nitride (Si3N4) balls to achieve higher speed capability, lower inertia, and reduced heat generation. This is common in high-speed spindles and precision instruments.
Q: What certifications do you hold for quality and environmental compliance?
We are certified to IATF 16949 (automotive quality management), RoHS, CE, and have SGS test reports for our products. These certifications cover our production processes and finished bearing performance.
Q: How do you ensure low noise and low vibration in stainless steel angular contact bearings?
We control raceway geometry, surface finish, and ball quality through precision grinding and honing. Each bearing is tested for noise and vibration before shipment, and we can meet specific decibel limits if required.
Q: What is the typical lead time for custom stainless steel angular contact bearings?
Lead time depends on complexity and quantity. Standard sizes are often available from stock. For custom designs, prototypes can be delivered in 2–4 weeks, and mass production follows after approval. We will provide a confirmed schedule with your quotation.
