KB100AR0 Bearing Product Overview & Core Advantages
The KB100AR0 is a high-precision thin section angular contact ball bearing designed for applications requiring exceptional rigidity and precise motion control. Manufactured to inch dimensions with a large 10-inch bore, this single-row bearing excels in handling combined radial and axial loads simultaneously due to its 30° contact angle. Its Reali-Slim open construction provides a compact, lightweight solution for space-constrained, high-performance machinery, offering reliable operation within a temperature range of -30°C to 110°C.

KB100AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides high rigidity, enabling the bearing to support significant combined loads, including a radial dynamic load of 1461 lbf and an axial static load of 3760 lbf.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight bore and OD tolerances, ensuring smooth, precise rotation and minimal runout for accurate positioning.
- Optimized Cage Design: The brass cage ensures stable ball guidance, reduces friction, and contributes to smooth operation at moderate speeds.
- Superior Material: Components made from chrome steel provide high hardness, wear resistance, and long service life under demanding conditions.
- Lightweight Construction: As a thin section bearing, it offers a significant weight reduction (0.71 lbs) without sacrificing performance, ideal for reducing rotational inertia.
KB100AR0 Bearing Typical Application Areas
- Robotics & Automation: Robot arm joints, rotary actuators, and precision gearing systems.
- Aerospace & Defense: Radar platforms, gyroscope gimbals, and satellite positioning mechanisms.
- Medical Equipment: CT scanner gantries, surgical robot rotators, and MRI component drives.
- Semiconductor Manufacturing: Wafer handling robots, precision stages, and stepper/scanner mechanisms.
- Industrial Machinery: Rotary tables, indexing heads, and high-precision spindles.
