|---|---|
| JB025 | Indicates a thin-section bearing with a 2.5" bore diameter. |
| C | Specifies the radial internal clearance group. |
| P | Denotes the bearing is equipped with contact seals for superior contamination exclusion. |
| 0 | A variant or suffix indicating specific design details within the series. |
JB025CP0 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a thin cross-section (0.3125" width) and low weight (0.19 lbs), the JB025CP0 minimizes system weight and envelope size without sacrificing performance, making it perfect for robotics and aerospace applications.
- Superior Sealing & Lubrication: The integrated contact seals effectively shield the chrome steel balls and raceways from contaminants while retaining the factory-applied lubricant. This results in a long service life and maintenance-free operation within a temperature range of -30°C to 110°C.
- High Load Capacity & Rigidity: The single row design with a brass cage provides stable operation and can support a dynamic radial load of 644 lbf and a static radial load of 1140 lbf, ensuring reliable performance under demanding conditions.
- Precision Engineering: Manufactured to ABEC-1 tolerance standards with a controlled radial internal clearance, this bearing delivers smooth, low-vibration, and precise rotational motion.
JB025CP0 Bearing Typical Application Areas
- Robotics: Joints, actuators, and rotary modules where lightweight and compact bearings are critical.
- Aerospace & Defense: Guidance systems, control surface mechanisms, and instrumentation requiring high reliability.
- Medical Equipment: Surgical robots, scanners, and diagnostic devices demanding precision and cleanliness.
- Industrial Automation: Rotary tables, indexing heads, and precision gearboxes.
- Optics and Instrumentation: Mounts for mirrors, lenses, and sensors where minimal deflection is required.
