K18013AR0 Bearing Product Overview & Core Advantages
The K18013AR0 is a metric thin-section angular contact ball bearing designed for applications requiring high precision and space optimization. This single-row bearing excels in handling combined loads, efficiently supporting both radial and significant axial loads in one direction due to its specific 30° contact angle. Manufactured to ABEC-1 precision standards, it offers reliable performance in compact designs where weight and cross-section are critical constraints. Its open design allows for custom lubrication schemes to meet specific operational requirements.

K18013AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: The bearing's 13mm cross-section and 180mm bore provide a large diameter in a minimal space, reducing overall system weight and size without sacrificing performance.
High Load Capacity: The 30° contact angle and robust chrome steel construction (rings and balls) enable high axial static load ratings (7339 lbf) alongside substantial radial dynamic (3047 lbf) and static (7405 lbf) load capacities, making it ideal for combined loading scenarios.
Precision & Rigidity: Manufactured to ABEC-1 tolerance standards, it ensures consistent running accuracy. The brass cage provides excellent guidance and stability, contributing to smooth operation.
Versatile Application Range: The open (non-sealed) design allows for the use of various lubricants, supporting operation within a temperature range of -30°C to 110°C.
K18013AR0 Bearing Typical Application Areas
- Aerospace & Defense: Actuators, control mechanisms, and radar platforms where weight and precision are paramount.
- Industrial Robotics: Rotary joints and arm linkages requiring high moment load capacity (21375 lbf static load moment) and compact design.
- Medical Equipment: High-precision imaging devices (CT/MRI scanners) and surgical robots.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
- Optical Instrumentation: Rotary tables and positioning systems.
