SB035AR0 Bearing Product Overview & Core Advantages
The SB035AR0 is a thin section angular contact ball bearing designed for applications requiring high precision and space optimization. Manufactured from stainless steel with a brass cage, it offers excellent corrosion resistance. Its primary advantage lies in its ability to support combined loads, efficiently handling both radial and significant axial loads in one direction due to its specified 30° contact angle. This makes it an ideal, compact solution for high-rigidity applications where standard bearings are not suitable.
SB035AR0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| SB | Reali-Slim Stainless Steel Bearing Series | Indicates a thin-section bearing designed for compact spaces. |
| 035 | Bore Diameter (3.5 Inches) | Specifies the inner diameter of the bearing. |
| A | 30° Contact Angle | Optimized for carrying high axial loads. |
| R0 | Radial Internal Clearance (0.0000 – 0.0005") | Specifies a precise internal fit for optimal performance. |
| Open (Seal Type) | No Seal / Shield | Enables higher speeds and allows for custom lubrication schemes. |
SB035AR0 Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The single row angular contact design, combined with a 30° contact angle and a robust brass cage, provides high rigidity and enables the bearing to support substantial combined loads. It has a radial dynamic load rating of 801 lbf and a significant axial static load rating of 1930 lbf.
Precision and Speed: Built to ABEC-1 tolerance class with a very tight radial internal clearance, this bearing ensures smooth, precise operation. The open design and brass cage contribute to its suitability for high-speed applications.
Durability and Environmental Resistance: The all-stainless steel construction (rings and balls) provides excellent corrosion resistance, making it suitable for harsh environments. It is pre-lubricated and operates within a temperature range of -30°C to 110°C.
SB035AR0 Bearing Typical Application Areas
The SB035AR0 is engineered for high-performance systems where space and weight are critical. Its key applications include:
- Robotics and Automation: Used in robotic arm joints and precision gearboxes.
- Aerospace and Defense: Ideal for gimbal systems, control mechanisms, and satellite components.
- Medical Equipment: Suitable for surgical robots and high-speed imaging devices.
- Semiconductor Manufacturing: Applied in precision stages and wafer handling equipment.
