KB080AR0 Bearing Product Overview & Core Advantages
The KB080AR0 is a thin section angular contact ball bearing designed for applications demanding high precision and space efficiency. As part of the Reali-Slim Open Bearings series, this single row bearing excels in handling combined loads, offering a significant axial static load capacity of 3260 lbf alongside its radial capabilities. Its compact cross-section, with a width of only 0.3125", makes it ideal for high-rigidity support in weight-sensitive and compact assemblies. Manufactured to ABEC-1 precision standards, it ensures reliable performance in precision instruments and automation equipment.

KB080AR0 Bearing Structural Features & Performance Benefits
Angular Contact Design: The 30° contact angle is engineered to support high axial static loads (3260 lbf) in one direction, making it superior to deep groove ball bearings for combination load applications.
Thin-Section Construction: With a consistent cross-section, this bearing provides maximum bearing size and load capacity within a minimal envelope, contributing to system high rigidity and weight reduction.
Precision Components: The chrome steel rings and balls, combined with a brass cage, ensure smooth operation, low noise, and extended service life under ABEC-1 precision tolerances.
Open Design & Lubrication: The open (unsealed) configuration permits the use of specialized lubricants for specific operational environments, supporting a wide temperature range from -30°C to 110°C.
KB080AR0 Bearing Typical Application Areas
The KB080AR0 is ideally suited for a range of precision machinery and automation systems where space constraints and load capacity are critical. Key sectors include:
- Robotics: Used in robotic arm joints and rotary actuators for precise motion control.
- Aerospace & Defense: Applied in gimbal systems, radar platforms, and guidance systems.
- Medical Equipment: Found in CT scanners, MRI machines, and surgical robots.
- Semiconductor Manufacturing: Utilized in wafer handling and precision positioning stages.
- Optical Instrumentation: Supports rotary stages in telescopes, surveying instruments, and laser systems.
