K16020AR0 Bearing Product Overview & Core Advantages
The K16020AR0 is a single row angular contact ball bearing from the Reali-Slim mm Metric series, engineered for applications demanding high precision and space efficiency. This bearing excels at handling combined loads, supporting significant radial and axial loads simultaneously due to its specified 30° contact angle. Manufactured to ABEC-1 precision tolerances, it ensures reliable performance in high-accuracy systems. Its compact cross-section, with a 20mm width relative to its 160mm bore, makes it an ideal solution for lightweight, rigid designs where space constraints are critical.

| Code Segment | Technical Meaning |
|---|---|
| K | Indicates the bearing is part of the Reali-Slim mm Metric series of thin-section bearings. |
| 160 | Specifies the bore diameter of 160 mm. |
| 20 | Specifies the cross-section width of 20 mm. |
| A | Denotes a 30° contact angle, optimized for handling high axial loads. |
| R0 | Signifies a specific internal design and radial internal clearance group (0.0000 – 0.0005"). |
K16020AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: The single row construction with a slim 20mm width provides a high load capacity within a minimal envelope, crucial for compact machinery. The 30° contact angle is engineered to efficiently support substantial combined radial and axial loads.
High-Precision Components: The rings and balls are manufactured from Chrome Steel for durability and high fatigue life. The brass cage ensures stable ball guidance, contributing to smooth operation and high rotational accuracy.
Precision and Rigidity: Built to ABEC-1 tolerance class, this bearing guarantees consistent performance and running accuracy. The specified tight radial internal clearance ensures minimal runout and high system rigidity.
Versatile Operation: The open seal type allows for custom lubrication strategies, while the standard lubricated condition and a temperature range of -30°C to 110°C make it suitable for a wide array of industrial environments.
K16020AR0 Bearing Typical Application Areas
The K16020AR0 is ideally suited for applications requiring a large bore, a slim profile, and high precision. Key industries and equipment include:
- Robotics: Rotary joints and actuator arms.
- Aerospace & Defense: Radar platforms, gimbal systems, and flight control mechanisms.
- Medical Equipment: CT scanners and MRI machinery.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables and indexing heads.
