SG140XP0 Bearing Product Overview & Core Advantages
The SG140XP0 is a high-precision Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series. Engineered for applications demanding compact cross-sections and high performance, this bearing is designed to simultaneously support combined loads, including significant radial, axial, and moment loads. Its stainless steel construction provides excellent corrosion resistance, making it ideal for applications where reliability and long service life in challenging environments are critical. The bearing is pre-lubricated for immediate use and adheres to ABEC-1 precision tolerances.
SG140XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| SG | Indicates the Reali-Slim series with a specific cross-section (e.g., "S" type). |
| 140 | Specifies the bore diameter of 14 inches. |
| X | Denotes a special feature or internal design; consult factory for specifics. |
| P0 | Corresponds to the ABEC-1 tolerance class, a standard level of precision. |
SG140XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single row bearing to support substantial radial, axial, and moment loads simultaneously, simplifying design and saving space.
- High Load Capacity: Engineered for demanding applications, it offers high dynamic and static load ratings for both radial (14,404 lbf dynamic) and axial (23,410 lbf dynamic) directions.
- Thin Section & Lightweight: With a 1-inch width and a 16-inch outside diameter, it provides a large diameter in a compact envelope, contributing to a low overall system weight (10.8 lbs).
- Corrosion Resistance & Durability: The stainless steel rings and balls, combined with a brass cage, ensure reliable operation in corrosive or clean environments.
- Pre-Lubricated & Ready-to-Install: The bearing comes lubricated from the factory, facilitating easy installation and immediate operation within a specified temperature range of -30°C to 110°C.
SG140XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring large booms, precise rotation, and high stiffness in a compact design. Key industries and equipment include:
- Robotics: Robotic arms and rotary joints.
- Aerospace & Defense: Radar platforms, gimbal systems, and satellite mechanisms.
- Medical Equipment: CT scanners and MRI machines.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables and indexing units.
