SA120CP0 Bearing Product Overview & Core Advantages
The SA120CP0 is a high-performance thin section bearing engineered for applications demanding precision and space optimization. As part of the Reali-Slim Stainless Steel Bearings series, this single row ball bearing is designed for radial load applications. Its primary advantage lies in its extremely slim cross-section (0.25" width) relative to its large 12" bore diameter, enabling compact and lightweight designs without sacrificing performance. Manufactured entirely from stainless steel with a brass cage, it offers excellent corrosion resistance and reliable operation, making it ideal for high-precision, weight-sensitive mechanisms.
SA120CP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SA | Indicates the bearing is part of the Reali-Slim series with a 1" cross-section. |
| 120 | Specifies the bore diameter of 12.0 inches. |
| C | Denotes the radial internal clearance group (C3 equivalent). |
| P0 | Specifies the ABEC-1 tolerance class for standard precision applications. |
SA120CP0 Bearing Structural Features & Performance Benefits
Ultra-Thin Cross-Section Design: The bearing's minimal width-to-bore ratio enables significant space and weight savings in complex assemblies, a critical feature for robotics and aerospace applications.
Corrosion-Resistant Construction: Manufactured with stainless steel rings and balls combined with a brass cage, the bearing delivers reliable performance in harsh environments and resists degradation.
Optimized Load Capacity: Despite its slim profile, it maintains a substantial radial dynamic load rating of 1078 lbf and a radial static load rating of 3720 lbf, ensuring durability under operational stresses.
Standard Precision & Clearance: The ABEC-1 tolerance class and controlled radial internal clearance provide consistent, smooth operation suitable for a wide range of industrial applications.
SA120CP0 Bearing Typical Application Areas
- Robotics: Joint actuators, rotary modules, and precision arms where space and weight are critical constraints.
- Aerospace & Defense: Guidance systems, gimbal mechanisms, and control surface actuators.
- Medical Equipment: Imaging systems (CT/MRI), surgical robots, and diagnostic instrument rotors.
- Semiconductor Manufacturing: Wafer handling robots, precision stages, and indexing tables.
- Optical & Instrumentation Systems: Rotary encoders, scanning mirrors, and precision positioning devices.
