K07020XP0 Bearing Product Overview & Core Advantages
The K07020XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim mm Metric Bearings series, designed for applications demanding compact cross-sections and high load capacity. This thin section bearing excels in handling combined loads, simultaneously supporting significant radial loads and axial loads from both directions. Its single row construction with a four point contact design provides exceptional rigidity and precise rotation, making it ideal for precision equipment and space-constrained assemblies requiring high reliability.
K07020XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K07020 | Denotes the bearing series (Reali-Slim) and core dimensions: 70mm bore, 110mm OD, 20mm width. |
| XP | Indicates Four Point Contact design, enabling the bearing to handle combined radial and bidirectional axial loads. |
| 0 | Specifies an Open (unsealed) construction, suitable for controlled environments or custom lubrication systems. |
K07020XP0 Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry creates four distinct contact points between the balls and raceways. This allows a single row bearingcombined loads (radial, axial, and moment loads), replacing the need for more complex bearing arrangements and saving space and weight.
High Load Capacity & Rigidity: Manufactured from Chrome Steel for both rings and balls, this bearing offers high dynamic and static load ratings. The robust Brass cage ensures stable ball guidance, contributing to smooth operation and high system rigidity under load.
Precision & Thin Section: Built to ABEC-1 tolerance class with tight dimensional control on bore, outside diameter, and width. The thin cross-section is a key feature of the Reali-Slim series, enabling lightweight and compact machine designs.
Versatile Lubrication: The bearing is supplied lubricated, ready for initial operation. The open design provides flexibility for the application of specialized greases or oil systems as required by specific operating conditions.
K07020XP0 Bearing Typical Application Areas
The K07020XP0 is engineered for high-performance applications where space, weight, and load capacity are critical. Common uses include:
- Robotics: Rotary joints and actuator arms.
- Aerospace & Defense: Gimbals, control mechanisms, and radar systems.
- Machine Tool: Rotary tables, indexing heads, and other precision positioning systems.
- Medical Equipment: CT scanners and advanced imaging devices.
- Semiconductor Manufacturing: Wafer handling and precision stages.
