Stainless Steel Bearing Cage

Shaoxing Shangyu Flight Seiko Machinery Co., Ltd. (FTM), leveraging over 30 years of technical design experience in high-precision bearing manufacturing, proudly presents our range of Stainless Steel Bearing Cages. As a specialist in non-standard and high-precision bearings (import substitution), FTM ensures every component meets the stringent demands of modern industrial applications.

Product Overview and Core Function

The stainless steel bearing cage is a critical internal component responsible for maintaining the performance and longevity of a bearing. Its primary function is to separate, position, and retain the rolling elements (balls or rollers) at equal intervals around the raceways. This precise spacing prevents direct contact between the rolling elements, minimizing frictional heat, reducing noise, and enabling the bearing to operate at higher speeds and under heavier loads.

FTM Material Excellence and Durability

FTM cages are meticulously manufactured from premium austenitic stainless steels: Grade 304 or Grade 316. This material selection is pivotal to the cage’s superior performance, especially in challenging operational settings:

• Exceptional Corrosion Resistance: Both 304 and the more robust 316 stainless steel (containing molybdenum) offer outstanding resistance to rust and oxidation. This makes our cages ideal for applications exposed to moisture, steam, corrosive chemicals, saline solutions, and sanitizing agents, such as those found in food and beverage processing, marine, and medical industries.
• High Temperature Stability: Stainless steel maintains its structural integrity and mechanical properties across a broad temperature spectrum, ensuring the cage does not deform or fail in high-heat environments where plastic or brass cages might degrade.
• Excellent Wear Resistance: The inherent hardness of the stainless steel provides strong resistance to wear and abrasion caused by constant movement against the rolling elements and potential contaminant ingress.

Frequently Asked Questions (FAQ)

1. What is the primary difference between a 304 and 316 stainless steel cage?
   The main difference is the presence of molybdenum in the 316 alloy. This addition significantly enhances its resistance to pitting and crevice corrosion, making the 316 cage the preferred choice for extremely aggressive chemical or high-salinity marine environments.

2. When should I choose a stainless steel cage over a standard stamped steel or brass cage?
   A stainless steel cage is recommended when the application involves exposure to moisture, chemicals, high humidity, or high temperatures. Stamped steel cages may rust, and plastic or nylon cages may deform or lose strength in extreme heat or chemical exposure.

3. Can FTM produce customized cage designs for existing bearings?
   Yes, absolutely. FTM specializes in R&D and manufacturing, allowing us to design and produce non-standard or customized stainless steel cages tailored to your specific dimensional, material, and performance requirements for specialized or legacy bearing applications.

4. How does the stainless steel cage affect the lubrication of the bearing?
   Stainless steel is chemically inert and does not react with most lubricants. The cage design maintains the precise spacing of the rolling elements, which is crucial for allowing the lubricant film to be maintained effectively between the elements and the raceways.

5. Are FTM stainless steel cages suitable for high-speed operations?
   Yes. The high-precision manufacturing and superior material strength of our stainless steel cages ensure excellent stability and minimal vibration at high rotational speeds, making them suitable for high-performance machinery.
