KA055BR0K Bearing Product Overview & Core Advantages
The KA055BR0K is a thin-section angular contact ball bearing designed for applications requiring high precision and compact design. As part of the Reali-Slim Open Bearings series with inch measurements, it excels in handling combined radial and axial loads simultaneously due to its specific 30° contact angle. Its single-row construction provides exceptional space-saving benefits while maintaining reliable performance in precision machinery and rotational systems where minimal cross-section is critical.
KA055BR0K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Significance |
|---|---|---|
| KA055 | Bearing series designation for thin-section angular contact bearings | Identifies the specific product family and size configuration |
| BR | Brass cage material | Provides excellent strength and durability for high-speed applications |
| 0K | Open construction without seals | Allows for custom lubrication schemes and maximum speed capability |
KA055BR0K Bearing Structural Features & Performance Benefits
Thin-Section Design: With a cross-section of only 0.25" between 5.5" bore and 6" outside diameter, this bearing enables compact machinery design while maintaining structural integrity.
Angular Contact Configuration: The 30° contact angle provides optimal combined load capacity, handling both radial loads (715 lbf dynamic rating) and substantial axial loads (1800 lbf static rating) efficiently.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional control (bore and OD tolerance: -0.0010" to 0") ensures high running accuracy and smooth operation.
Premium Materials: Chrome steel rings and balls combined with brass cage deliver exceptional durability and reliable performance across the operating temperature range of -30°C to 110°C.
KA055BR0K Bearing Typical Application Areas
- Robotics and Automation: Joint bearings in robotic arms and precision positioning systems
- Aerospace Systems: Actuators, control mechanisms, and instrumentation where weight and space are critical
- Medical Equipment: Imaging systems, surgical robots, and diagnostic machinery requiring high precision
- Semiconductor Manufacturing: Wafer handling equipment and precision positioning stages
- Optical Instruments: Rotary stages and positioning systems in measurement and inspection equipment
