SC055XP0 Bearing Product Overview & Core Advantages
The SC055XP0 is a Four Point Contact thin section bearing engineered for applications requiring exceptional space optimization and precision performance. Manufactured from stainless steel with a brass cage, this single row ball bearing is designed to simultaneously handle significant combined loads, including radial, axial, and moment loads, within an extremely compact cross-section. Its ABEC-1 precision and corrosion-resistant construction make it ideal for high-reliability and clean-environment applications.
SC055XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SC | Indicates Stainless Steel construction for corrosion resistance. |
| 055 | Specifies the bore diameter of 5.5 inches. |
| X | Denotes the cross-section series (Width: 0.375", OD: 6.25"). |
| P0 | Refers to the standard ABEC-1 tolerance class and open (unsealed) design. |
SC055XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The raceway geometry allows a single bearing to support substantial combined radial and axial loads as well as moment loads, effectively replacing more complex bearing arrangements and simplifying assembly.
- Thin Section Construction: With a consistent cross-section (0.375" width), this design maximizes the bore diameter relative to the overall envelope, offering significant weight and space savings in compact machinery.
- High Load Capacity: Engineered to handle high dynamic and static load ratings (Radial Dynamic: 1687 lbf, Axial Static: 7060 lbf) despite its slim profile, ensuring durability and long service life.
- Corrosion-Resistant Materials: The use of stainless steel for rings and balls, combined with a brass cage, provides excellent resistance to corrosion, making it suitable for harsh or washdown environments and eliminating the need for protective coatings.
- Precision Performance: Manufactured to ABEC-1 standards with tight dimensional tolerances and controlled radial internal clearance for smooth, precise operation in demanding applications.
SC055XP0 Bearing Typical Application Areas
- Robotics and Automation: Rotary joints, robotic arms, and gantry systems where compact design and high moment load capacity are critical.
- Aerospace and Defense: Gimbal systems, radar platforms, and control surface actuators requiring lightweight and corrosion-resistant components.
- Medical and Semiconductor Equipment: Precision stages, scanning equipment, and cleanroom machinery that benefit from stainless steel construction and high positional accuracy.
- Optical and Instrumentation Systems: Rotary tables and positioning devices where minimal deflection and smooth motion are paramount.
