KG250XP0 Bearing Product Overview & Core Advantages
The KG250XP0 is a high-performance Four Point Contact thin section bearing designed for applications requiring exceptional load moment capacity in a compact envelope. This single row ball bearing features an open design and is engineered to simultaneously handle significant radial loads, axial loads, and moment loads. Its inch-dimensioned, Reali-Slim construction provides a high load-to-size ratio, making it ideal for space-constrained, high-precision machinery where rigidity and load capacity are critical.
KG250XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KG250XP0 | Manufacturer's specific model designation for this thin section, four-point contact bearing series. |
| Open | No integral seals or shields, allowing for custom lubrication schemes and higher potential speeds. |
| Four Point Contact | The ball raceway geometry allows each ball to contact the raceways at four points, enabling the bearing to support combined radial, axial, and moment loads. |
| ABEC-1 | Specifies the precision tolerance class, ensuring consistent running accuracy and performance. |
KG250XP0 Bearing Structural Features & Performance Benefits
High Load Moment Capacity: The unique Four Point Contact design is the core feature, enabling the KG250XP0 to support a high Dynamic Load Moment of 188838 lbf and a Static Load Moment of 554900 lbf. This makes it exceptionally capable in applications subject to tilting or overturning forces.
Combined Load Support: This bearing is engineered to handle combined loads effectively, with high ratings for both radial dynamic load (19360 lbf) and axial dynamic load (33780 lbf).
Precision & Rigidity: Manufactured to ABEC-1 precision tolerances with a very tight radial internal clearance (0.0000 – 0.0005"), this bearing provides precise motion control and high system rigidity.
Durable Construction: The use of Chrome Steel for rings and balls, combined with a Brass cage, ensures long-term durability, wear resistance, and stable operation.
KG250XP0 Bearing Typical Application Areas
- Robotics: Rotary joints and actuators requiring high moment load capacity.
- Aerospace & Defense: Gimbals, radar platforms, and control surface actuators.
- Machine Tool: Rotary tables, indexing heads, and other precision positioning systems.
- Medical Equipment: CT scanners and MRI systems where smooth, precise rotation is essential.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
