SD045AR0 Bearing Product Overview & Core Advantages
The SD045AR0 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 Angular Contact ball bearing is designed to simultaneously support combined radial and axial loads. Its single row construction, combined with a 30° contact angle, provides exceptional accuracy and rigidity in a compact cross-section, making it ideal for high-reliability systems where weight and space are critical constraints.
SD045AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SD045 | Indicates the bearing series (Reali-Slim) and size designation (4.5" bore) |
| A | Signifies Angular Contact design |
| R0 | Specifies Radial Internal Clearance group (0.0000 – 0.0005") |
SD045AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The Angular Contact design with a 30° contact angle provides superior resistance to combined loads, handling a radial dynamic load rating of 1931 lbf and a significant axial static load rating of 4570 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control on bore, outside diameter, and width for consistent, high-accuracy performance.
- Corrosion Resistance: Constructed entirely from Stainless Steel (rings and balls) with a Brass cage, offering excellent corrosion resistance and suitability for harsh environments.
- Optimized for Compact Designs: With a slim cross-section of just 0.5" width and a large bore relative to its outside diameter, it maximizes space utilization in lightweight assemblies.
- Pre-lubricated: Comes lubricated from the factory for immediate use, operating effectively within a temperature range of -30°C to 110°C.
SD045AR0 Bearing Typical Application Areas
- Robotics: Joint and actuator bearings in robotic arms and precision automation systems.
- Aerospace & Defense: Guidance systems, radar platforms, and actuation mechanisms requiring lightweight and corrosion-resistant components.
- Medical Equipment: Imaging devices (MRI, CT scanners) and surgical robots where precision and reliability are paramount.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Optical Instrumentation: Rotary stages in measuring devices and positioning systems.
