K02520AR0 Bearing Product Overview & Core Advantages
The K02520AR0 is a metric thin-section angular contact ball bearing from the Reali-Slim series, designed for applications demanding high precision and space-saving designs. As a single-row angular contact bearing, it is engineered to support significant combined loads, handling both radial forces and unidirectional axial loads efficiently. Its compact cross-section, with a 25 mm bore and 65 mm outside diameter in a mere 20 mm width, makes it ideal for high-rigidity applications where space is constrained. Manufactured to ABEC-1 precision and pre-lubricated, it delivers reliable performance in high-speed and precision motion systems.
K02520AR0 Bearing Model Code Explained, Specifications & Naming Convention
The model number K02520AR0 can be broken down as follows:
- K: Indicates a metric series thin-section bearing (Reali-Slim).
- 02: Specifies the cross-section series/code.
- 52: Represents the bore diameter code (corresponding to 25 mm).
- 0: Series identifier.
- A: Denotes a 30° contact angle, optimized for handling higher axial loads.
- R0: Indicates standard radial internal clearance and potentially other standard features (e.g., open design, standard cage).
K02520AR0 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single-row angular contact design with a 30° contact angle provides excellent resistance to combined (radial and axial) loads. The robust chrome steel construction of rings and balls ensures high dynamic (2546 lbf) and static (2500 lbf radial, 4663 lbf axial) load ratings.
- Precision & Speed: Built to ABEC-1 tolerance standards with a tight radial internal clearance (0.0000 – 0.0005 inches), this bearing supports smooth, precise operation. The brass cage enhances stability and is suitable for higher rotational speeds.
- Space-Saving Design: As a thin-section bearing, it offers a large bore relative to its cross-section, enabling compact and lightweight machinery designs (weight: 0.31 kg).
- Versatile Operating Range: Pre-lubricated and capable of operating within a temperature range of -30°C to 110°C, it is suited for various industrial environments.
K02520AR0 Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for applications requiring high accuracy, compact design, and reliable performance under combined loads:
- Robotics: Joint and arm actuators requiring high rigidity and precision.
- Aerospace & Defense: Guidance systems, radar platforms, and actuation mechanisms.
- Medical Equipment: Surgical robots, imaging scanners, and precise diagnostic instruments.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables, indexing heads, and high-precision spindles.
