Custom Single Row Ball Rollers Bearing

As a specialized division of Shaoxing Shangyu Flight Seiko Machinery Co., Ltd. (FTM), we leverage our over 30 years of technical design expertise to deliver bespoke bearing solutions. Our Custom Single Row Ball Roller Bearings are a prime example of our commitment to high-precision manufacturing and import substitution excellence.

FTM’s single row ball roller bearings are not merely components; they are precision-engineered mechanical parts designed to meet the rigorous demands of sophisticated machinery.

• Dual Load Capacity: These bearings are specifically configured to efficiently support both significant radial loads (perpendicular to the shaft) and axial loads (parallel to the shaft). This versatility allows for simplified machine designs and consolidation of components.
• Spherical Rolling Elements: The unique spherical rolling elements are the cornerstone of this design. They facilitate a wider distribution of contact stresses across the raceway, which is crucial for minimizing friction and ensuring an exceptionally smooth and quiet operation. This design intrinsically leads to increased mechanical efficiency and lower operational temperatures.
• Enhanced Precision Grades: We are equipped to manufacture these bearings up to P4 and P2 precision classes (in accordance with ISO standards). This level of precision is critical for applications requiring minimal runout, high rotational speeds, and exact positioning accuracy.

• Quality Assurance: Utilizing advanced manufacturing processes and stringent quality control, we guarantee the reliability and longevity of our bearings, offering a true alternative to international import brands.
• Industry Application Mastery: Our professional technical team provides proven high-quality bearing solutions for demanding sectors such as engineering machinery, textile machinery, automotive, aerospace, and robotics.

Extending Knowledge: Key Design Considerations

The performance of a single row ball roller bearing is influenced by several critical parameters:

• Contact Angle: The angle between the line connecting the points of contact of the ball and the raceway, and a line perpendicular to the bearing axis. Customizing this angle allows us to optimize the bearing for a desired ratio of axial-to-radial load support.
• Internal Clearance: This is the distance one ring can be moved relative to the other. Proper clearance is vital to compensate for thermal expansion during operation and prevent excessive preload or uncontrolled stress.
• Cage Material: The retainer or cage (which keeps the rolling elements separated) can be customized using materials like stamped steel, machined brass, or polymer compounds (e.g., polyamide), depending on the required speed, temperature, and lubrication method.

FAQ

• What is the maximum operating temperature for FTM’s standard single row ball roller bearings?
  The maximum operating temperature is highly dependent on the cage material and the type of lubricant utilized. With standard steel cages and high-temperature grease, they can typically operate up to 120°C. We can customize high-temperature polymer or specialized steel cages for applications exceeding this.

• How does FTM ensure the P2/P4 precision class during manufacturing?
  Achieving P2/P4 precision involves ultra-fine grinding and honing of the raceways and rolling elements, followed by 100% inspection using sophisticated measuring equipment (such as non-contact gauges) to verify dimensional accuracy, runout, and surface finish.

• Can these bearings be used in high-speed applications like spindle systems?
  Yes, due to their low friction and high precision, our custom single row ball roller bearings are suitable for many high-speed applications. For extreme speeds, we optimize the internal design, including using precision cages and ceramic rolling elements, to manage centrifugal forces and heat generation.

• What information does FTM require to provide a custom bearing quote?
  We require the basic dimensions (bore, OD, width), the required precision class (e.g., P4), the operational load profile (radial and axial loads), the required speed, and the environmental conditions (temperature, exposure to contaminants).

• What is the typical lead time for a non-standard, custom-designed single row ball roller bearing?
  Lead times vary based on the complexity and volume. Standard custom orders generally take 6 to 8 weeks from final design approval to delivery, while highly complex, unique non-standard designs may require longer.
