SD047XP0 Bearing Product Overview & Core Advantages
The SD047XP0 is a Four Point Contact thin section bearing from the Reali-Slim Stainless Steel series, designed for applications requiring high precision and space optimization. This single row ball bearing is engineered to simultaneously handle significant combined loads, including radial, axial, and moment loads, within an extremely compact cross-section. Manufactured entirely from stainless steel with a brass cage, it offers excellent corrosion resistance and reliable performance in demanding environments, making it ideal for high-accuracy and high-reliability applications.

SD047XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single row bearing to support substantial combined radial, axial, and moment loads simultaneously, simplifying assembly and reducing the need for multiple bearing arrangements.
- High Load Capacity in a Slim Profile: Despite its thin 0.5" cross-section, this bearing offers impressive dynamic and static load ratings (e.g., 2496 lbf radial dynamic, 3860 lbf axial dynamic), providing robust performance where space is constrained.
- Corrosion Resistance & Durability: Constructed with stainless steel rings and balls and a brass cage, the bearing is well-suited for harsh environments, including those with exposure to moisture or chemicals.
- Precision & Stability: The ABEC-1 tolerance class and controlled radial internal clearance ensure consistent running accuracy and smooth operation, contributing to the overall system's performance.
SD047XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a compact, high-capacity solution. Key industries and equipment include:
- Robotics: Robotic arms, joints, and rotary actuators.
- Aerospace & Defense: Gimbal systems, radar platforms, and guidance systems.
- Medical Equipment: CT scanners, MRI machines, and surgical robots.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical and Instrumentation: Rotary tables, positioning devices, and precision measuring equipment.
