SD250CP0 Bearing Product Overview & Core Advantages
The SD250CP0 is a Reali-Slim Stainless Steel Bearings designed for applications requiring ultra-thin cross-sections and corrosion resistance. This single row ball bearing excels in handling radial loads within compact spaces where standard bearings cannot fit. Manufactured entirely from stainless steel with a brass cage, it offers reliable performance in demanding environments. Its ABEC-1 precision and pre-lubrication ensure smooth operation, making it ideal for precision mechanisms requiring high reliability and space optimization.
SD250CP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| SD | Reali-Slim® Series Designation | Indicates the ultra-thin section bearing family. |
| 250 | Bore Diameter (2.5") | Specifies the 25" internal bore size. |
| C | Radial Internal Clearance | Defines the specific internal clearance group for optimal performance. |
| P | Open (No Seal/Shield) | Signifies an open bearing design, allowing for custom lubrication or high-speed applications. |
| 0 | Lubricated | Indicates the bearing is supplied with factory-applied lubricant. |
SD250CP0 Bearing Structural Features & Performance Benefits
- Ultra-Thin Section Design: With a cross-section of only 0.5", this bearing enables significant space and weight savings in compact assemblies without compromising performance.
- Corrosion-Resistant Construction: The use of stainless steel for both rings and balls ensures excellent resistance to corrosion, making it suitable for harsh environments, including those requiring washdown or exposure to chemicals.
- High Load Capacity for its Size: Despite its slim profile, it offers a high radial static load rating of 17,440 lbf and a dynamic load rating of 4,689 lbf, providing robust support in radial applications.
- Precision & Stability: The ABEC-1 tolerance class and controlled radial internal clearance guarantee consistent running accuracy and smooth operation, which is critical for precision instruments.
- Optimized Cage Design: The brass cage provides superior strength and stability, contributing to reliable performance at moderate speeds and in various operating conditions.
SD250CP0 Bearing Typical Application Areas
- Aerospace & Defense: Actuation systems, gimbal mechanisms, and control surfaces where lightweight and corrosion-resistant components are critical.
- Semiconductor Manufacturing: Wafer handling robots and precision stages requiring cleanroom-compatible and high-precision bearings.
- Medical Equipment: Surgical robots, imaging devices (MRI, CT scanners), and diagnostic instruments demanding reliable and non-magnetic performance.
- Food & Beverage Processing: Conveyor systems and filling machines where stainless steel construction meets hygiene standards and withstands frequent washdowns.
- Robotics & Automation: Joints, gears, and rotary tables in collaborative and industrial robots that benefit from compact bearing dimensions and high rigidity.
