KD120XP0 Bearing Product Overview & Core Advantages
The KD120XP0 is a high-performance Four Point Contact Ball Bearing from the Reali-Slim Open Bearings series, designed in inch dimensions. This single row, open-type bearing is engineered to handle significant combined loads, simultaneously supporting substantial radial, axial, and moment loads in a compact, thin-section cross-section. Its design is optimized for applications requiring high precision and reliability within a constrained space envelope, offering an exceptional balance of load capacity and minimal weight.
KD120XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| KD120 | Indicates the specific bearing series and nominal bore diameter of 12 inches. |
| XP0 | Signifies the bearing is Open (no seal or shield) and is pre-Lubricated from the factory. |
KD120XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows the bearing to support combined radial, axial, and moment loads efficiently with a single bearing row, simplifying assembly and saving space.
- High Load Capacity: Engineered with Chrome Steel rings and balls, it offers high dynamic and static load ratings (e.g., Radial Dynamic: 4178 lbf, Axial Static: 21380 lbf) for demanding applications.
- Precision & Rigidity: Manufactured to ABEC-1 tolerance standards with a controlled radial internal clearance (0.0000" – 0.0005"), ensuring consistent performance, smooth operation, and high system rigidity.
- Thin-Section & Lightweight: With a cross-section of only 0.5 inches and a weight of 2.25 lbs, it is ideal for weight-sensitive and compact machinery designs without sacrificing strength.
- Durable Cage: The Brass cage provides excellent durability and guidance for the balls, contributing to stable operation under high speeds and varying loads.
KD120XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications where high load capacity must be combined with a slim profile. Key industries and equipment include:
- Robotics (Robotic arms, rotary joints)
- Aerospace (Control mechanisms, actuation systems)
- Semiconductor Manufacturing Equipment (Wafer handling robots, precision stages)
- Medical Equipment (CT scanners, MRI gantries)
- Industrial Rotating Tables and Indexing Heads
