SD040XP0 Bearing Product Overview & Core Advantages
The SD040XP0 is a Four Point Contact thin section bearing designed for applications requiring high precision and compact design. Manufactured entirely from stainless steel (rings and balls) with a brass cage, it offers excellent corrosion resistance. Its defining feature is the ability to simultaneously support combined loads, including significant radial, axial, and moment loads, making it an ideal solution for high-rigidity systems where space and weight are critical constraints.
SD040XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD | Indicates the Reali-Slim series, a family of thin-section bearings. |
| 040 | Specifies the bore diameter of 4 inches. |
| X | Denotes the cross-section (width) of the bearing, which is 0.5" for this series. |
| P | Specifies a Four Point Contact ball bearing construction. |
| 0 | Indicates an open (unsealed) design and standard internal clearance. |
SD040XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: A single-row bearing that functions like a double-row unit, capable of supporting combined radial, axial, and moment loads simultaneously. This design provides exceptional stiffness and load capacity in a very compact envelope.
- Thin Section Construction: With a consistent cross-section across all sizes, this bearing is engineered for lightweight, space-saving applications without sacrificing performance.
- Corrosion-Resistant Materials: The use of stainless steel for all critical components ensures reliable operation in harsh environments and contributes to a long service life.
- Precision Performance: Manufactured to ABEC-1 tolerance standards, this bearing delivers consistent running accuracy and smooth operation for precision equipment.
- High Load Capacity: Engineered to handle substantial dynamic and static loads, including a high axial static load rating of 7700 lbf, making it suitable for demanding applications.
SD040XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications requiring a compact, high-capacity solution:
- Robotics and Automation (Robotic arms, rotary joints)
- Aerospace Actuation Systems and Control Surfaces
- Medical Equipment (MRI scanners, surgical robots)
- Semiconductor Manufacturing Equipment
- Precision Rotary Tables and Indexing Systems
- Radar and Satellite Communication Systems
