SF350AR0 Bearing Product Overview & Core Advantages
The SF350AR0 is a high-precision thin-section angular contact ball bearing engineered for applications demanding exceptional rigidity and precise motion control. Manufactured with stainless steel rings and balls and a brass cage, this bearing is designed to simultaneously handle significant combined loads, including radial and axial loads in one direction. Its compact, single-row design is ideal for space-constrained, high-reliability applications requiring ABEC-1 precision and consistent performance.
SF350AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| SF350 | Indicates the bearing series and size (35" bore, 36.5" OD, 0.75" width). |
| A | Signifies a 30° contact angle, optimized for carrying high axial loads. |
| R0 | Denotes a standard radial internal clearance (0.0000 – 0.0005"). |
SF350AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The 30° contact angle and robust single-row design provide high rigidity, enabling the bearing to support substantial combined radial and axial static loads (48,380 lbf radial, 32,580 lbf axial).
- Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore/OD tolerance: -0.0020"– 0"), ensuring smooth, accurate operation and minimal runout.
- Corrosion Resistance & Durability: Constructed entirely from stainless steel and featuring a brass cage, this bearing offers excellent corrosion resistance and is suitable for use in a wide temperature range (-30°C to 110°C).
- Optimized for Moment Loads: The design provides a high static load moment capacity of 139,700 lbf, making it suitable for applications involving overturning moments.
SF350AR0 Bearing Typical Application Areas
This bearing is ideally suited for demanding applications where precision, compactness, and high load capacity are critical. Key industries and equipment include:
- Robotics and Automation: Robotic arms, rotary joints, and precision positioning stages.
- Aerospace & Defense: Radar platforms, gimbal systems, and flight control mechanisms.
- Medical Equipment: CT scanners, MRI machines, and surgical robot joints.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
