K12008XP0 Bearing Product Overview & Core Advantages
The K12008XP0 is a metric thin-section bearing engineered for applications demanding high precision and space optimization. As a Four Point Contact ball bearing, it is uniquely designed to simultaneously support combined radial and axial loads from any direction, making it an exceptionally versatile component. Its compact cross-section, with a width of only 8 mm, allows for lightweight and streamlined designs without sacrificing performance. Manufactured to ABEC-1 tolerance standards, this bearing ensures reliable operation in high-accuracy assemblies.
K12008XP0 Bearing Model Code Explained, Specifications & Naming Convention
The K12008XP0 model number provides detailed technical specifications:
- K: Identifies the bearing as part of the Reali-Slim® metric series.
- 12008: Specifies the bore diameter (120 mm) and cross-section (8 mm width).
- XP: Denotes a Four Point Contact ball bearing design.
- 0: Indicates a standard radial internal clearance.
K12008XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The raceway geometry allows the bearing to handle significant combined loads (radial, axial, and moment loads) efficiently in a single, compact unit, reducing the need for complex multi-bearing arrangements.
- High Load Capacity: With a dynamic load rating of 1638 lbf (radial) and 2540 lbf (axial), it offers robust performance for its thin cross-section.
- Precision Engineering: The ABEC-1 tolerance and controlled radial internal clearance ensure smooth, precise rotation and minimal runout, which is critical for accuracy.
- Durable Construction: Components made from Chrome Steel and a Brass cage provide excellent durability and stable operation across the specified temperature range.
- Pre-lubricated: Comes lubricated from the factory for immediate use and long-term, maintenance-free operation in many applications.
K12008XP0 Bearing Typical Application Areas
This bearing is ideal for machinery and equipment where space and weight are at a premium, and high rotational accuracy is required. Key sectors include:
- Robotics: Joints and actuators.
- Aerospace & Defense: Gimbals, control systems, and radar apparatus.
- Medical Equipment: CT scanners and surgical robots.
- Semiconductor Manufacturing: Precision stages and wafer handling robots.
- Optical Instrumentation: Rotary tables and positioning systems.
