K10020AR0 Bearing Product Overview & Core Advantages
The K10020AR0 is a single row angular contact ball bearing designed for applications requiring high precision and reliable performance. As part of the Reali-Slim mm Metric series of thin section bearings, it offers a compact design with a 100 mm bore and a 20 mm width, enabling space-saving solutions in complex machinery. Its primary advantage lies in its ability to support combined loads, efficiently handling significant radial and axial loads simultaneously due to its specified 30° contact angle. Manufactured to ABEC-1 tolerance standards, this bearing is ideal for applications demanding high running accuracy and high rigidity.

K10020AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: The compact cross-section (20mm width) provides a high load capacity relative to its size, making it ideal for weight and space-critical applications. This contributes to the overall high rigidity of the assembly.
Superior Load Capacity: With a radial dynamic load rating of 4253 lbf and a notably high axial static load rating of 9458 lbf, this bearing is engineered to handle significant combined loads effectively.
Precision Components: The use of Chrome Steel for both rings and balls, combined with a Brass cage, ensures durability, smooth operation, and extended service life. The ABEC-1 precision class guarantees consistent and reliable performance.
Pre-Lubricated for Immediate Use: The bearing comes lubricated from the factory, ensuring immediate operational readiness and protection during the initial run-in period.
K10020AR0 Bearing Typical Application Areas
The K10020AR0 is suited for a wide range of precision machinery and equipment, including:
- Robotics and automation arms (for joint and pivot points)
- Medical Equipment such as MRI scanners and surgical robots
- Aerospace Actuation Systems and control surfaces
- Semiconductor Manufacturing Equipment
- Precision Rotary Tables and indexing heads
