SG042XP0 Bearing Product Overview & Core Advantages
The SG042XP0 is a Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series. Engineered as a thin section bearing with inch dimensions, it delivers exceptional performance in compact spaces. Its single row design with four-point contact enables it to simultaneously support combined radial and axial loads from any direction, making it ideal for applications requiring high precision and reliability where space and weight are critical constraints.
SG042XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SG | Indicates the Reali-Slim series with thin cross-section. |
| 042 | Specifies the nominal bore diameter in inches (4.25"). |
| X | Denotes a Four Point Contact ball bearing construction. |
| P0 | Specifies an Open seal type and standard ABEC-1 precision tolerance. |
SG042XP0 Bearing Structural Features & Performance Benefits
- Four-Point Contact Design: The unique raceway geometry allows a single row bearingcombined radial and axial loads in both directions, simplifying assembly and reducing component count.
- Thin Section & Lightweight: With a consistent 1" cross-section across all sizes, it offers substantial weight and space savings. The stainless steel rings and cage contribute to a total weight of just 3.8 lbs.
- High Load Capacity: Engineered for demanding applications, it features impressive dynamic and static load ratings (Radial Dynamic: 7917 lbf, Axial Dynamic: 11260 lbf).
- Corrosion Resistance: Constructed entirely from stainless steel and brass, the bearing is inherently corrosion-resistant and ROHS compliant, suitable for harsh environments.
- Precision Performance: Manufactured to ABEC-1 tolerance class with a controlled radial internal clearance, ensuring smooth and precise operation.
SG042XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a compact, lightweight, and versatile solution with high load capacity. Common uses include:
- Robotics and Automation joints and actuators
- Aerospace control mechanisms and gimbal systems
- Medical Equipment such as MRI scanners and surgical robots
- Semiconductor Manufacturing equipment
- Precision Rotary Tables and indexing systems
