SG040XP0 Bearing Product Overview & Core Advantages
The SG040XP0 is a Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series, designed for applications demanding compact cross-sections and high performance. This single row bearing is engineered to simultaneously support combined loads, including significant radial, axial, and moment loads, all within an ultra-thin profile. Its construction from stainless steel offers excellent corrosion resistance, making it ideal for high-reliability and precision applications where space and weight are critical constraints.

| Code Segment | Technical Meaning |
|---|---|
| SG | Indicates the Reali-Slim series with a thin cross-section. |
| 040 | Specifies the bore diameter of 4 inches. |
| X | Denotes a Four Point Contact design, enabling the bearing to handle combined loads. |
| P | Signifies that the bearing is lubricated from the factory. |
| 0 | Indicates an open (unsealed) construction. |
SG040XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single row bearing to support combined radial, axial, and moment loads efficiently, simplifying assembly and saving space compared to traditional bearing arrangements.
- High Load Capacity: Engineered for substantial dynamic and static load ratings (Radial Dynamic: 7979 lbf, Axial Dynamic: 11260 lbf), this bearing is capable of handling demanding applications.
- Stainless Steel Construction: Both rings and balls are manufactured from stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments, including food processing and medical equipment.
- Precision & Rigidity: Manufactured to ABEC-1 tolerance standards, the bearing ensures consistent performance and smooth operation. The brass cage provides stability and durability at moderate speeds.
- Ultra-Thin Section: With a cross-section of only 1" on a 4" bore, the Reali-Slim design minimizes weight and space requirements, which is critical in robotics, aerospace, and semiconductor equipment.
SG040XP0 Bearing Typical Application Areas
- Robotics: Rotary joints, actuator arms, and manipulators where compact size and moment load capacity are essential.
- Aerospace & Defense: Control mechanisms, gimbal systems, and radar platforms benefiting from lightweight and corrosion-resistant components.
- Semiconductor Manufacturing: Wafer handling robots and precision stages requiring high precision and clean operation.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic devices where reliability and stainless steel hygiene are paramount.
- Food & Beverage Machinery: Mixers, fillers, and conveyors operating in washdown environments.
