JA055XP0 Bearing Product Overview & Core Advantages
The JA055XP0 is a precision-engineered Four Point Contact Ball Bearing from the Reali-Slim® sealed series, designed for applications requiring exceptional thin-section performance. This sealed bearing combines a compact cross-section with the ability to support significant combined loads, including radial, axial, and moment loads simultaneously. Manufactured to ABEC-1 precision standards, it delivers high reliability and consistent performance in space-constrained, high-accuracy environments.
JA055XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| JA055 | Series designation for Reali-Slim® sealed bearings with specific internal geometry. |
| XP0 | Indicates specific internal clearance, seal type, and lubrication configuration. |
| Sealed | Integrated seals protect against contamination and retain lubricant. |
JA055XP0 Bearing Structural Features & Performance Benefits
This bearing's performance stems from its optimized thin-section design and material selection:
- Four Point Contact Design: The raceway geometry allows a single row of balls to efficiently support combined radial, axial, and moment loads, making it highly versatile and compact.
- High Load Capacity: Engineered for substantial dynamic and static loads, with ratings of 908 lbf radial dynamic and 1480 lbf axial dynamic.
- Precision & Rigidity: Manufactured to ABEC-1 tolerance class with tight dimensional control on the bearing bore and outside diameter (±0.0010"), ensuring precise fit and high system rigidity.
- Integrated Sealing & Lubrication: The sealed construction with factory-applied lubricant provides protection from contaminants and offers long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
- Durable Material Construction: Components made from Chrome Steel (rings and balls) and a Brass cage ensure durability, smooth operation, and long service life.
JA055XP0 Bearing Typical Application Areas
The JA055XP0 is ideally suited for applications where a slim profile, high precision, and the ability to handle complex loads are critical. Key industries and equipment include:
- Robotics: Robotic arms, joints, and rotary actuators.
- Aerospace & Defense: Gimbal systems, radar platforms, and control surfaces.
- Medical Equipment: CT scanners, MRI machines, and surgical robots.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Automation: Rotary tables, indexing heads, and precision gearboxes.
