SA100AR0 Bearing Product Overview & Core Advantages
The SA100AR0 is a Reali-Slim Stainless Steel Angular Contact Ball Bearing designed for applications requiring exceptional precision and corrosion resistance. This single row bearing features a 30° contact angle, enabling it to handle significant combined loads—both radial and axial—simultaneously. Its ultra-thin cross-section (0.25" width) allows for compact, lightweight designs without sacrificing performance. Manufactured entirely from stainless steel with a brass cage, it offers reliable operation in demanding environments and is pre-lubricated for immediate use.
SA100AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| SA | Stainless Steel, Angular Contact | Indicates corrosion-resistant material and bearing type optimized for combined loads. |
| 100 | Bore Diameter: 10.000" | Specifies the large, precise inner diameter for shaft mounting. |
| A | 30° Contact Angle | Optimized for high axial load capacity in one direction. |
| R0 | Radial Internal Clearance: 0.0000 – 0.0005" | Specifies a very tight clearance group for high precision and rigidity. |
SA100AR0 Bearing Structural Features & Performance Benefits
Thin-Section Design: The bearing dimensions (10" bore, 10.5" OD, 0.25" width) create an extremely slim profile, enabling significant space and weight savings in machinery while maintaining a large shaft diameter.
High Load Capacity: The 30° contact angle and stainless steel construction provide excellent resistance to combined loads, with a static axial load rating of 2640 lbf and a high static load moment capacity of 10370 lbf.
Corrosion Resistance & Precision: Manufactured from stainless steel with an ABEC-1 precision class, this bearing is ideal for applications requiring dimensional stability and resistance to harsh environments. The brass cage ensures smooth operation and durability.
Ready-to-Install: The bearing is pre-lubricated and features an open seal type, allowing for easy re-lubrication if necessary and operation within a temperature range of -30°C to 110°C.
SA100AR0 Bearing Typical Application Areas
- Aerospace & Defense: Gimbal systems, radar platforms, and actuator mechanisms.
- Semiconductor Manufacturing: Precision wafer handling robots and positioning stages.
- Medical Equipment: MRI scanners, robotic surgery arms, and rotary tables requiring corrosion resistance.
- Industrial Automation: Thin-section robotics, rotary unions, and high-precision indexing tables.
