SA045XP0 Bearing Product Overview & Core Advantages
The SA045XP0 is a Four Point Contact thin section bearing designed for applications requiring exceptional space optimization and precision. As part of the Reali-Slim Stainless Steel Bearings series, it combines a large bore diameter with an extremely slim cross-section, offering a compact and lightweight solution. Its four point contact design enables it to simultaneously support significant combined loads—including radial, axial, and moment loads—making it ideal for high-accuracy and high-reliability systems where space and weight are critical constraints.

| 045 | Indicates a bore diameter of 4.5 inches. |
| X | Extra-Thin cross-section series (Width = 0.25"). |
| P | Four Point Contact design for combined load capacity. |
| 0 | Open (unsealed) construction. |
SA045XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The raceway geometry allows the bearing to support combined radial, axial, and moment loads efficiently with a single bearing row, simplifying assembly and reducing system weight.
- Thin Section Construction: With a consistent 0.25" cross-section, this bearing enables compact, lightweight designs without sacrificing large bore capacity, critical for robotics and aerospace applications.
- Stainless Steel & Brass Construction: Rings and balls made from stainless steel provide excellent corrosion resistance, while the brass cage ensures smooth operation and durability.
- Precision Tolerances: Manufactured to ABEC-1 precision standards with tight bore and OD tolerances, ensuring reliable performance in high-precision applications.
- High Load Capacity: Engineered to handle substantial dynamic and static loads, including a Radial Dynamic Load Rating of 809 lbf and an Axial Dynamic Load Rating of 1310 lbf.
SA045XP0 Bearing Typical Application Areas
- Robotics: Rotary joints, actuator arms, and manipulators requiring high precision and compact bearing dimensions.
- Aerospace & Defense: Gimbal systems, radar platforms, and guidance systems where lightweight and corrosion-resistant components are essential.
- Medical Equipment: MRI and CT scanner components, surgical robots, and precision instrumentation.
- Semiconductor Manufacturing: Wafer handling robots and precision stages demanding high rigidity and minimal deflection.
- Optical and Imaging Systems: Pan-tilt units and mirror mounts requiring smooth, precise rotation under combined loads.
