SB100AR0 Bearing Product Overview & Core Advantages
The SB100AR0 is a high-performance thin section angular contact ball bearing engineered for precision applications requiring exceptional rigidity and accuracy. Manufactured from stainless steel with a 30° contact angle, this single-row bearing is optimized to support combined loads, handling significant radial and axial thrust simultaneously. Its Reali-Slim cross-section provides a compact, lightweight solution without compromising on load capacity, making it ideal for space-constrained, high-reliability systems. The bearing is pre-lubricated for immediate operation and conforms to ABEC-1 precision tolerances, ensuring consistent performance and long service life.

SB100AR0 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single-row angular contact design, combined with a 30° contact angle and a brass cage, provides high rigidity and enables the bearing to support substantial combined radial and axial loads (Radial Dynamic: 1461 lbf, Axial Static: 3760 lbf).
Precision & Stability: Manufactured to ABEC-1 tolerance standards with tight dimensional controls (Bore/OD tolerance: -0.0014" to 0"), ensuring smooth operation, minimal runout, and precise rotational accuracy in demanding applications.
Corrosion Resistance & Lightweight: Constructed entirely from stainless steel (rings and balls), the bearing offers excellent corrosion resistance. The thin-section design results in a low weight of just 0.71 lbs, reducing rotational inertia.
Optimized for Pre-Lubrication: The open design allows for easy application of specific lubricants, accommodating the specified temperature range of -30°C to 110°C.
SB100AR0 Bearing Typical Application Areas
- Aerospace & Defense: Gimbal systems, radar platforms, and guidance mechanisms.
- Semiconductor Manufacturing: Precision stages, wafer handling robots, and inspection equipment.
- Medical Equipment: MRI scanners, surgical robots, and diagnostic imaging devices.
- Industrial Automation: Robotic arms, rotary tables, and high-precision indexing units.
