JA055CP0 Bearing Product Overview & Core Advantages
The JA055CP0 is a sealed thin-section ball bearing engineered for applications demanding compact design and reliable performance. As part of the Reali-Slim series, this single-row bearing excels in handling radial loads within space-constrained assemblies. Its inch-dimension design, featuring a large 5.5" bore in a slim 0.25" cross-section, makes it ideal for precision machinery where weight and space savings are critical. The integrated seals and factory-applied lubrication ensure long-term, maintenance-free operation, providing high reliability in demanding industrial environments.

JA055CP0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: The JA055CP0 achieves exceptional space efficiency with its 0.25" width while maintaining a substantial 5.5" bore diameter. This compact construction enables significant weight reduction in large-diameter applications without compromising performance.
Enhanced Load Capacity: With a radial dynamic load rating of 685 lbf and radial static load rating of 1750 lbf, this bearing delivers reliable performance under substantial radial loads. The ISO radial rating of 1442 lbf further validates its robust load-handling capabilities.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore and outside diameter tolerance: -0.0010" to 0"), ensuring consistent performance and easy installation in precision applications.
Superior Material Composition: Constructed with chrome steel rings, chrome steel balls, and brass cage for optimal strength, durability, and smooth operation across the specified temperature range of -30°C to 110°C.
Maintenance-Free Operation: The sealed design combined with factory lubrication provides long service life without requiring additional maintenance, while the controlled radial internal clearance (0.0000 - 0.0005") ensures consistent performance.
JA055CP0 Bearing Typical Application Areas
The JA055CP0 thin-section sealed bearing is ideally suited for:
- Robotics and Automation: Joint bearings in robotic arms and automation equipment requiring large bore diameters and compact cross-sections
- Aerospace Systems: Control mechanisms, actuation systems, and instrumentation where weight savings are critical
- Medical Equipment: Precision imaging devices, surgical robots, and diagnostic machinery demanding reliable, maintenance-free operation
- Semiconductor Manufacturing: Wafer handling equipment and precision positioning stages requiring contamination control
- Optical and Defense Systems: Radar antennas, surveillance equipment, and precision optical mounts needing large diameter support with minimal weight
- Industrial Machinery: Light-duty rotating assemblies where space constraints prevent using standard cross-section bearings
