Bộ sưu tập: Stainless Flange Ball Bearings
Stainless flanged ball bearings are corrosion-resistant flange bearings designed for compact installation, precise axial positioning, and stable rotation in humid, washdown, food-processing, marine, medical, and light industrial environments. Compared with standard flanged ball bearings, stainless flanged bearings provide better resistance to rust, moisture, cleaning agents, and mild corrosive conditions.
CXE supplies stainless steel flange ball bearings in multiple sizes, materials, seal types, and precision grades for OEM and industrial applications. These bearings are commonly used in conveyor rollers, guide wheels, small motors, automation equipment, packaging machinery, medical devices, and precision assemblies.
What Are Stainless Flanged Ball Bearings?
Stainless flanged ball bearings are flanged ball bearings manufactured with stainless steel rings and rolling elements. The outer ring includes a flange structure that helps the bearing locate accurately inside a housing or mounting hole. This flange prevents the bearing from moving through the housing and improves positioning stability in compact mechanical designs.

Why Choose Stainless Steel Flange Bearings?
Stainless steel flange bearings are selected when standard bearing steel may rust or fail prematurely in wet, humid, or corrosive environments. Their flange design simplifies installation, while the stainless steel material improves durability in demanding applications.
- Better corrosion resistance than chrome steel bearings
- Compact flange design for easy mounting
- Stable axial positioning in housings and panels
- Suitable for humid, washdown, and clean environments
- Available in open, shielded, and sealed designs
- Suitable for OEM customization and bulk supply
Stainless Steel Materials
440C Stainless Steel Flanged Ball Bearings
440C stainless steel is commonly used for stainless flanged ball bearings because it offers high hardness, good wear resistance, and stable running performance. It is suitable for precision equipment, small motors, automation systems, guide rollers, and general industrial applications where corrosion resistance and mechanical strength are both required.
316 Stainless Steel Flanged Ball Bearings
316 stainless steel provides stronger corrosion resistance than 440C stainless steel, especially in wet, marine, chemical, food-processing, and washdown environments. 316 stainless flanged bearings are recommended for applications exposed to moisture, cleaning agents, salt spray, or mildly corrosive liquids.
Ceramic Hybrid Stainless Flange Bearings
Ceramic hybrid stainless flange bearings use stainless steel rings with ceramic balls. This design can reduce friction, lower vibration, improve speed capability, and increase resistance to corrosion. They are commonly used in high-speed motors, medical equipment, dental tools, and precision machinery.
Types of Stainless Flanged Ball Bearings
Open Stainless Flanged Bearings
Open stainless flanged bearings have no shields or seals. They provide low friction and are suitable for clean environments where contamination is limited and relubrication may be required.
ZZ Shielded Stainless Flanged Bearings
ZZ shielded stainless flange bearings use metal shields on both sides. They help protect the internal rolling elements from dust and particles while maintaining low rotational resistance. They are commonly used in small motors, fans, instruments, and automation equipment.
2RS Sealed Stainless Flanged Bearings
2RS sealed stainless flanged bearings use rubber seals on both sides. They offer improved protection against moisture, dust, grease leakage, and light contamination. They are suitable for humid environments, washdown equipment, food machinery, and outdoor compact devices.
Common Applications
Food Processing Equipment
Stainless flanged ball bearings are widely used in food-processing machinery where corrosion resistance, easy cleaning, and stable operation are important. They are suitable for small conveyors, packaging equipment, guide rollers, and light-duty food machinery.
Marine and Humid Environments
In marine or high-humidity environments, stainless steel flange bearings help reduce rust and extend service life. 316 stainless steel is especially suitable for applications exposed to saltwater mist or frequent moisture.
Medical and Laboratory Equipment
Medical devices and laboratory instruments often require compact bearings with clean operation, corrosion resistance, and low noise. Stainless flanged bearings provide stable positioning and smooth rotation in compact assemblies.
Automation and Precision Assemblies
Automation systems often use stainless flange bearings for guide wheels, small rollers, positioning mechanisms, and compact drive systems. The flange structure helps simplify assembly and maintain accurate bearing alignment.
Small Motors and Fans
Stainless flanged ball bearings are commonly used in small electric motors, cooling fans, micro motors, and compact drive units. Their low friction and precise positioning help improve running stability and reduce vibration.

How to Select Stainless Flanged Ball Bearings
Choose the Right Stainless Steel Material
For general precision applications, 440C stainless steel is a good option because it offers hardness and wear resistance. For highly corrosive, wet, food-grade, or marine environments, 316 stainless steel is usually the better choice.
Select the Proper Seal Type
Open bearings are suitable for clean and low-friction applications. ZZ shielded bearings are suitable for dust protection and higher speed. 2RS sealed bearings are recommended when moisture, cleaning liquids, or contaminants are present.
Confirm Size and Mounting Requirements
When selecting a stainless flange bearing, confirm bore diameter, outside diameter, width, flange diameter, flange thickness, shaft fit, and housing fit. Correct dimensions help ensure stable positioning and smooth operation.
Consider Speed, Load, and Environment
Stainless flanged ball bearings are mainly used in light-duty and precision applications. For higher speed, lower friction, or special environmental conditions, material, lubrication, clearance, and seal design should be selected carefully.

Frequently Asked Questions
What are stainless flanged ball bearings used for?
They are used for compact mounting and precise axial positioning in equipment exposed to moisture, humidity, cleaning agents, or light corrosion. Common applications include food machinery, medical devices, conveyor rollers, automation equipment, small motors, and guide wheels.
What is the difference between stainless flanged bearings and standard flanged bearings?
The main difference is material. Stainless flanged bearings provide better resistance to rust and corrosion, while standard flanged bearings are usually made from chrome steel and are better suited for dry general-purpose applications.
Are stainless flange bearings suitable for washdown environments?
Yes. Stainless flange bearings, especially 316 stainless steel and 2RS sealed types, are suitable for many humid and washdown applications. The final selection should depend on cleaning chemicals, temperature, speed, and load requirements.
Should I choose 440C or 316 stainless steel?
Choose 440C stainless steel when hardness, wear resistance, and running precision are more important. Choose 316 stainless steel when corrosion resistance is the main requirement, especially in marine, food-processing, chemical, or wet environments.
Are stainless flanged ball bearings the same as mounted bearings?
No. Stainless flanged ball bearings have a flange on the outer ring for positioning inside a housing or panel. Mounted bearings usually refer to complete bearing units with a housing, such as pillow block bearings or flange bearing units.
Can CXE provide custom stainless flange bearings?
Yes. CXE can support custom stainless flange bearing sizes, materials, seals, lubrication, clearance, and OEM requirements based on customer drawings or application needs.
