K34008XP0 Bearing Product Overview & Core Advantages
The K34008XP0 is a metric thin-section bearing specifically engineered for applications demanding compact design and high load capacity in a minimal cross-section. As a Four Point Contact Ball Bearing, it is uniquely capable of supporting combined radial and axial loads from any direction simultaneously. Its single-row design with a large 340 mm bore and a narrow 8 mm width makes it an ideal solution for space-constrained, high-precision machinery requiring ABEC-1 precision and reliable performance.
K34008XP0 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| K34008 | Indicates a metric thin-section bearing with a 340 mm bore and 8 mm width. |
| XP0 | Specifies the bearing's internal design and Four Point Contact geometry, optimized for moment load capacity. |
| (Inherent: Open) | No seal, allowing for higher speeds and custom lubrication schemes. |
| (Inherent: Lubricated) | Comes pre-lubricated for immediate operation. |
K34008XP0 Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The raceway geometry allows the bearing to support significant combined loads and high moment loads (rated load moment: 1728 ft-lbf), making it exceptionally versatile.
- High Load Capacity: Engineered with Chrome Steel rings and balls, it delivers a high dynamic load rating (Radial: 2976 lbf, Axial: 4971 lbf) and static load rating (Radial: 7625 lbf, Axial: 19065 lbf) for its compact cross-section.
- Precision & Rigidity: Manufactured to ABEC-1 tolerance standards with a controlled radial internal clearance, ensuring smooth, precise operation and high system rigidity.
- Durability & Stability: The brass cage provides excellent guidance and stability at operational speeds, contributing to long service life and consistent performance across a temperature range of -30°C to 110°C.
K34008XP0 Bearing Typical Application Areas
This bearing is ideally suited for applications where a large diameter is required but axial space is limited. Key industries and equipment include:
- Robotics: Rotary joints and actuators.
- Aerospace: Control mechanisms, gimbal systems, and radar platforms.
- Medical Equipment: CT scanners and MRI machines.
- Semiconductor Manufacturing: Precision stages and wafer handling robots.
- Optical Instrumentation: Rotary tables and positioning systems.
