SD042XP0 Bearing Product Overview & Core Advantages
The SD042XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Stainless Steel Bearings series. Engineered with an ultra-thin cross-section (Width: 0.5"), it delivers exceptional space and weight savings without compromising performance. Its stainless steel construction provides superior corrosion resistance, while the four-point contact design enables it to simultaneously support combined radial and axial loads from any direction. This makes it an ideal solution for compact, high-precision applications requiring high reliability and durability.
SD042XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| SD042 | Indicates the specific bearing size series (Bore: 4.25", OD: 5.25") within the Reali-Slim family. |
| XP | Denotes the Four Point Contact design, optimized for handling combined loads. |
| 0 | Specifies an Open (unsealed) configuration, allowing for custom lubrication schemes. |
SD042XP0 Bearing Structural Features & Performance Benefits
- Four-Point Contact & High Load Capacity: The unique raceway geometry allows a single bearing to support significant radial loads (Dynamic: 2355 lbf, Static: 3190 lbf) and high axial loads (Dynamic: 3600 lbf, Static: 7980 lbf) in both directions, simplifying assembly and reducing component count.
- Precision & Rigidity: Manufactured to ABEC-1 precision tolerances with tight dimensional control (Bore/OD tolerance: -0.0008"– 0"), ensuring smooth operation and accurate positioning in high-precision mechanisms.
- Corrosion-Resistant Construction: Both rings and balls are made from Stainless Steel, and the Brass cage ensures reliable performance in corrosive or wash-down environments, enhancing bearing longevity.
- Optimized for Compact Design: The thin-section design (Cross-section: 0.5") provides a large bore relative to its outer diameter, enabling the design of lighter, more compact machinery and systems.
SD042XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications where space, weight, and corrosion resistance are critical. Key industries and equipment include:
- Robotics: Joint and actuator bearings in robotic arms and precision positioning systems.
- Aerospace & Defense: Guidance systems, radar platforms, and actuation mechanisms.
- Medical Equipment: Scanning and imaging devices (e.g., CT, MRI) and surgical robots.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
- Food & Beverage Processing: Machinery requiring frequent wash-downs and corrosion resistance.
