SD210CP0 Bearing Product Overview & Core Advantages
The Reali-Slim Stainless Steel Bearing represents a specialized thin-section bearing solution engineered for applications demanding compact design and corrosion resistance. This single row ball bearing is designed primarily for radial load applications. Its defining characteristic is the minimal cross-section, achieved through a large 21" bore diameter relative to its 0.5" width, enabling significant space and weight savings in machinery. Constructed entirely from stainless steel with a brass cage, it offers excellent corrosion resistance and reliable performance. The bearing is pre-lubricated and features an open design, making it suitable for a wide temperature range from -30°C to 110°C.
SD210CP0 Bearing Model Code Explained, Specifications & Naming Convention
| Feature | Description | Technical Implication |
|---|---|---|
| Reali-Slim | Product Series | Denotes the thin-section bearing family, characterized by a large bore-to-cross-section ratio. |
| Stainless Steel | Material Construction | Indicates rings and balls are made from stainless steel, providing superior corrosion resistance. |
| Open | Seal Type | No contact seals, allowing for higher possible speeds and easier re-lubrication, but requires a clean operating environment. |
| ABEC-1 | Tolerance Class | Specifies standard precision level for runout and dimensional tolerances, suitable for many general industrial applications. |
SD210CP0 Bearing Structural Features & Performance Benefits
- Ultra-Thin Cross-Section: The primary structural feature is the extremely slim 0.5" width, which enables the design of lightweight and compact assemblies without sacrificing a large bore diameter. This is critical for saving space and reducing inertia in rotating systems.
- Corrosion-Resistant Construction: The use of stainless steel for both rings and balls, combined with a brass cage, ensures long-term reliability in humid, corrosive, or wash-down environments where standard carbon steel bearings would fail.
- Robust Load Capacity: Despite its thin section, this bearing offers a substantial radial dynamic load rating of 4274 lbf and a high radial static load rating of 14706 lbf, making it capable of handling significant radial forces in its compact form factor.
- Pre-Lubricated & Wide Temperature Range: The bearing comes pre-lubricated, facilitating easy installation and immediate operation. It is rated for a temperature range of -30°C to 110°C, ensuring performance stability across various operating conditions.
SD210CP0 Bearing Typical Application Areas
This thin-section bearing is ideally suited for applications where space constraints, weight reduction, and corrosion resistance are paramount. Key industries and equipment include:
- Aerospace & Defense: Actuation systems, gimbal mechanisms, and radar platforms.
- Semiconductor Manufacturing: Robotic arms, wafer handling equipment, and precision stages.
- Food & Beverage Processing: Conveyor rollers, filling machines, and packaging equipment requiring frequent wash-downs.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic imaging devices.
- Robotics: Joints and actuators in collaborative and industrial robots where a large hollow shaft is needed for cabling.
