| Code Segment | Technical Meaning |
|---|---|
| K | Metric Series Identifier (Reali-Slim mm) |
| 250 | Bore Diameter: 250 mm |
| 13 | Cross-Section Width: 13 mm |
| XP0 | Specific internal design & clearance (Four Point Contact, Open, ABEC-1 precision) |
K25013XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows the bearing to accommodate combined radial, axial, and moment loads simultaneously, providing versatile load-carrying capacity in a compact envelope.
- High Rigidity & Precision: Manufactured to ABEC-1 tolerance class with a minimal radial internal clearance (0.0000 – 0.0005"), ensuring precise shaft guidance, smooth rotation, and high system rigidity.
- Thin-Section Construction: With a slim 13mm width and large 250mm bore, it maximizes space efficiency and weight reduction (0.77 kg) while maintaining structural integrity.
- Durable Material Composition: Components made from Chrome Steel (rings and balls) and a Brass cage deliver high strength, wear resistance, and stable operation across a temperature range of -30°C to 110°C.
- Optimized Load Ratings: High dynamic and static load ratings (Radial Dynamic: 4671 lbf, Axial Dynamic: 7502 lbf) ensure long service life under demanding operating conditions.
K25013XP0 Bearing Typical Application Areas
- Robotics & Automation: Rotary joints, robotic arms, and precision positioning systems.
- Aerospace & Defense: Radar platforms, gimbal systems, and satellite mechanisms.
- Medical Equipment: CT scanners, MRI systems, and surgical robot joints.
- Semiconductor Manufacturing: Wafer handling robots and precision stages.
- Industrial Machinery: Rotary tables, indexing heads, and other compact, high-precision rotary applications.
