KA090XP0 Bearing Product Overview & Core Advantages
The KA090XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series, designed for applications demanding high load capacity and compact design in inch dimensions. This single row bearing is engineered to simultaneously support significant radial loads, axial loads in both directions, and moment loads, making it an ideal solution for space-constrained, high-precision machinery requiring exceptional rigidity and reliability.
KA090XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KA090 | Base model number, indicating the specific bearing size and series (9" bore, 9.5" OD, 0.25" width). |
| XP0 | Suffix denoting an Open (unsealed) construction and standard ABEC-1 precision tolerance. |
KA090XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows a single row bearing to handle combined radial, axial, and moment loads efficiently, replacing the need for more complex bearing arrangements and saving valuable space.
- High Load Capacity: Engineered with Chrome Steel rings and balls, this bearing offers high dynamic and static load ratings (Radial Dynamic: 1212 lbf, Axial Dynamic: 2040 lbf), ensuring durability under demanding conditions.
- Precision & Rigidity: Manufactured to ABEC-1 tolerance standards with a controlled radial internal clearance (0.0000 – 0.0005"), it provides consistent performance and high running accuracy for smooth operation.
- Optimized Cage & Lubrication: The Brass cage ensures stable ball guidance at operational speeds. The bearing comes pre-lubricated for immediate use within a wide temperature range of -30°C to 110°C.
- Thin-Section Profile: With a cross-section of just 0.25", it is part of the Reali-Slim family, enabling lightweight and compact design solutions without sacrificing performance.
KA090XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications where high load capacity and a minimal cross-section are critical. Key industries and equipment include:
- Robotics: Robotic arms and joints requiring compact, high-moment capacity bearings.
- Aerospace & Defense: Actuators, control surfaces, and radar systems.
- Medical Equipment: MRI and CT scanners, surgical robots.
- Semiconductor Manufacturing: Precision stages and wafer handling equipment.
- Industrial Automation: Rotary tables, indexing heads, and precision gearboxes.
