K36020AR0 Bearing Product Overview & Core Advantages
The K36020AR0 is a high-precision Angular Contact Ball Bearing engineered for demanding applications requiring superior performance under combined loads. Featuring a single row design with a 30° contact angle, it is optimized to handle significant radial loads and simultaneous axial loads in one direction. Manufactured to ABEC-1 tolerance standards, this bearing offers high running accuracy and reliability. Its compact cross-section, defined by a 360 mm bore and a 20 mm width, makes it an ideal solution for space-constrained, high-rigidity systems. The bearing comes pre-lubricated for immediate operation.
K36020AR0 Bearing Model Code Explained, Specifications & Naming Convention
The model number K36020AR0 can be broken down as follows:
- K: Metric Thin Section Bearing series (Reali-Slim®)
- 360: Bore diameter of 360 mm
- 20: Cross-section Width of 20 mm
- A: Angular Contact design with a 30° contact angle
- R0: Specified radial internal clearance (0.0000 – 0.0005")
K36020AR0 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row angular contact design, combined with a 30° contact angle and robust construction, provides excellent resistance to combined radial and axial loads. It offers a high radial dynamic load rating of 8124 lbf and a static load moment rating of 66528 lbf.
- Precision Engineering: Manufactured to ABEC-1 precision class, this bearing ensures smooth, low-vibration operation, which is critical for high-performance machinery.
- Optimized Material Selection: The use of Chrome Steel for rings and balls, along with a Brass cage, ensures high durability, wear resistance, and stable operation at high speeds.
- Pre-Lubricated for Immediate Use: The bearing is supplied with lubrication, facilitating easy installation and providing initial protection.
K36020AR0 Bearing Typical Application Areas
The K36020AR0 is ideally suited for applications where space is limited and high precision under combined loads is required. Key industries and equipment include:
- Robotics: Rotary joints and precision arms.
- Aerospace: Actuation systems, radar platforms, and gyroscopes.
- Semiconductor Manufacturing Equipment: Precision stages and wafer handling robots.
- Medical Equipment: CT scanners and MRI systems.
- Industrial Automation: Rotary tables and indexing heads.
