SF110AR0 Bearing Product Overview & Core Advantages
The SF110AR0 is a high-precision thin section angular contact ball bearing engineered for applications demanding exceptional rigidity and accuracy. Constructed entirely from stainless steel with a brass cage, this single-row bearing is designed to support combined loads, handling significant radial and axial forces simultaneously. Its 30° contact angle optimizes it for high moment load capacity, making it an ideal choice for compact, weight-sensitive systems requiring high reliability and long service life.
SF110AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF110 | Indicates the Reali-Slim® thin-section bearing series with a 1-inch cross-section and 10-inch bore diameter. |
| A | Signifies the 30° contact angle, which is optimized for supporting high axial and moment loads. |
| R0 | Specifies the radial internal clearance group (0.0000" – 0.0005") for precision operation. |
| (Open) | The bearing features an open (unsealed) design, allowing for custom lubrication schemes and maximum speed capability. |
SF110AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design, combined with a 30° contact angle and a robust brass cage, provides high rigidity. This enables the bearing to handle substantial combined radial and axial loads, with a remarkable static load moment rating of 45,850 lbf.
- Precision & Accuracy: Manufactured to ABEC-1 tolerance standards with tight bore and OD tolerances, this bearing ensures smooth, precise rotation, which is critical for high-accuracy applications.
- Corrosion Resistance: The use of stainless steel for both rings and balls provides excellent corrosion resistance, making it suitable for harsh environments and clean applications.
- Optimized for Thin-Section Design: With a compact cross-section of only 0.75", this bearing maximizes space and weight savings without compromising on bearing performance or load ratings.
SF110AR0 Bearing Typical Application Areas
- Robotics: Rotary joints and arm assemblies where high moment stiffness is critical.
- Aerospace & Defense: Gimbals, radar platforms, and control surface actuators requiring precision and reliability.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Medical Equipment: CT scanners and MRI systems where smooth, precise motion is essential.
- Industrial Automation: Rotary tables and indexing heads.
