SB110AR0 Bearing Product Overview & Core Advantages
The SB110AR0 is a single row angular contact ball bearing designed for precision applications requiring high reliability and exceptional performance. Manufactured from stainless steel with a brass cage, this bearing is engineered to handle significant combined loads, including both radial and axial forces. Its 30° contact angle optimizes it for applications with substantial thrust loads. As part of the Reali-Slim series, it features a thin cross-section, enabling compact and lightweight designs without compromising on load capacity or rigidity. The open design allows for custom lubrication schemes, making it versatile for various operational environments.

|---|---|
| SB | Indicates the Reali-Slim® bearing series with thin cross-section. |
| 110 | Specifies the bore diameter in inches (11.0"). |
| A | Denotes a 30° contact angle, optimized for high axial load capacity. |
| R0 | Signifies an open (unsealed) construction, allowing for custom lubrication. |
SB110AR0 Bearing Structural Features & Performance Benefits
High Load Capacity & Rigidity: The single row angular contact design, combined with a 30° contact angle, provides excellent resistance to combined radial and axial loads. The stainless steel construction of rings and balls ensures high corrosion resistance and durability, contributing to consistent performance under load.
Precision Engineering: Manufactured to ABEC-1 tolerance standards, this bearing offers reliable running accuracy. The tight radial internal clearance (0.0000 – 0.0005") ensures precise operation and minimal vibration.
Optimized Cage Design: The brass cage provides superior strength and stability, enabling smooth operation at moderate speeds and effective distribution of lubricant.
Thin-Section Advantage: The Reali-Slim design achieves a significant reduction in weight and cross-section while maintaining high static load moment capacity (15,440 lbf), ideal for space-constrained applications.
SB110AR0 Bearing Typical Application Areas
- Aerospace & Defense: Actuators, control systems, and guidance mechanisms.
- Robotics: Robotic arms, joints, and precision positioning systems.
- Medical Equipment: Surgical robots, imaging devices, and diagnostic instruments.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
