K20020XP0 Bearing Product Overview & Core Advantages
The K20020XP0 is a metric thin-section four-point contact ball bearing engineered for applications demanding high precision and compact design. As part of the Reali-Slim series, it offers a superior cross-section-to-bore ratio, enabling significant space and weight savings. Its four-point contact design allows it to simultaneously support combined radial and axial loads from any direction, making it an exceptionally versatile and high-rigidity solution for precision rotary systems.
K20020XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K | Indicates a metric series thin-section bearing. |
| 200 | Specifies the bore diameter of 200 mm. |
| 20 | Indicates the cross-section width of 20 mm. |
| XP0 | Denotes a specific internal design and four-point contact geometry. The bearing is lubricated from the factory. |
K20020XP0 Bearing Structural Features & Performance Benefits
- Four-Point Contact & High Rigidity: The single-row design with a four-point contact raceway provides high moment stiffness and can handle combined loads efficiently, simplifying bearing arrangements.
- Superior Load Capacity: Engineered with chrome steel rings and balls, it offers high dynamic and static load ratings (Radial Dynamic: 7295 lbf, Axial Dynamic: 11309 lbf) for its compact cross-section.
- Precision & Stability: Manufactured to ABEC-1 tolerance class with a controlled radial internal clearance (0.0000 – 0.0005"), ensuring smooth, precise, and repeatable operation.
- Robust Construction: The brass cage ensures reliable ball guidance and is suitable for a wide operating temperature range of -30°C to 110°C.
- Space-Saving Design: With a 200 mm bore and only 20 mm width, this thin-section bearing is ideal for applications where minimizing envelope size and weight (1.57 kg) is critical.
K20020XP0 Bearing Typical Application Areas
This bearing is ideally suited for high-precision machinery and systems where space constraints and weight are primary design considerations.
- Robotics: Rotary joints and actuators.
- Aerospace & Defense: Gimbals, radar platforms, and control surfaces.
- Medical Equipment: CT scanners and precision rotary tables.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
