SD140XP0 Bearing Product Overview & Core Advantages
The SD140XP0 is a Four Point Contact thin section bearing designed for applications requiring high precision and space optimization. Manufactured from stainless steel with a brass cage, this single row ball bearing excels at simultaneously handling combined radial and axial loads. Its compact cross-section and ABEC-1 precision make it ideal for high-reliability, compact assemblies where weight and space are critical constraints.
SD140XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| SD | Reali-Slim® Series Designation | Identifies the bearing as part of the high-precision thin-section family. |
| 14 | Bore Diameter (14") | Specifies the large, 14-inch inner diameter. |
| 0 | Cross-Section Code | Indicates a specific, ultra-thin radial cross-section relative to the bore size. |
| XP | Four Point Contact Design | The core feature enabling high axial load capacity from both directions. |
| 0 | Open (Unsealed) | Designed for controlled environments or custom sealing solutions. |
SD140XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Geometry: The raceway design allows the bearing to support significant combined radial and axial loads in a compact, single-row package, simplifying assembly and reducing weight.
- High Load Capacity: Engineered to handle substantial dynamic and static loads, with an axial static load rating of 24,800 lbf, making it robust for demanding applications.
- Precision & Rigidity: The ABEC-1 tolerance class and tight internal clearance ensure smooth, predictable operation, contributing to system accuracy and high rigidity.
- Corrosion Resistance: Constructed entirely from stainless steel (rings and balls) with a brass cage, offering excellent resistance to corrosion and suitability for a wide temperature range from -30°C to 110°C.
- Space & Weight Savings: As a thin section bearing with a 0.5" width, it provides a large diameter in a minimal envelope, crucial for lightweight and compact machinery design.
SD140XP0 Bearing Typical Application Areas
This bearing is ideally suited for:
- Robotics: Joints and rotary actuators requiring high moment load capacity and compact design.
- Aerospace & Defense: Gimbals, radar platforms, and control surfaces where precision, weight, and reliability are paramount.
- Medical Equipment: CT scanners, MRI machines, and surgical robots that demand smooth, precise rotation and corrosion resistance.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
- Optical Instrumentation: Rotary tables and positioning systems in measuring devices.
