SB070XP0 Bearing Product Overview & Core Advantages
The SB070XP0 is a Four Point Contact thin section bearing from the Reali-Slim® Stainless Steel series, engineered for applications demanding compact design and high precision in inch-sized machinery. This single row ball bearing is distinguished by its ability to support significant combined loads, including radial, axial, and moment loads, simultaneously. Manufactured entirely from stainless steel (rings and balls) with a brass cage, it offers excellent corrosion resistance and reliable performance in a slim cross-section, making it ideal for space-constrained, high-reliability applications.
SB070XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SB | Indicates a Stainless Steel thin section bearing from the Reali-Slim® series. |
| 070 | Specifies the nominal bore diameter of 7 inches. |
| XP | Denotes the Four Point Contact design, enabling the bearing to handle combined radial, axial, and moment loads. |
| 0 | Indicates an Open (unsealed) configuration, suitable for environments where external sealing is provided or contamination is minimal. |
SB070XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single bearing to efficiently support combined radial, axial, and moment loads, simplifying assembly and reducing the need for multiple bearing arrangements. This results in a compact and lightweight solution.
- Thin Section & High Load Capacity: Despite its slim width of 0.3125 inches, the bearing offers impressive load ratings (Radial Dynamic: 1498 lbf, Axial Dynamic: 2450 lbf), making it a robust component for its cross-sectional size.
- Precision & Stability: Built to ABEC-1 precision tolerances with a controlled radial internal clearance, it ensures smooth, predictable operation and high running accuracy.
- Corrosion Resistance & Durability: The use of stainless steel for all critical components and a brass cage provides excellent resistance to corrosion and ensures reliable performance in harsh environments, with an operating temperature range of -30°C to 110°C.
SB070XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications where a large diameter, slim profile, and multi-directional load capacity are critical. Key industries and equipment include:
- Aerospace & Defense: Gimbal systems, radar platforms, and actuator mechanisms.
- Robotics: Robotic joints and rotary actuators requiring high moment load capacity.
- Medical & Semiconductor Equipment: Precision rotary tables, scanning arms, and indexing devices.
- Industrial Automation: Rotary unions, packaging machinery, and precision turntables.
