Product Description
The PLBU20 CN Ewellix Bearing Unit is a precision housing unit designed for locating (fixed-side) arrangement applications in ball screw support systems. This unit is engineered to provide reliable axial positioning and support in dual-bearing configurations, making it an essential component for high-precision linear motion systems that require fixed-point shaft support.
Key Specifications:
- Inner Dimension: 20mm shaft diameter
- Bearing Configuration: 2x 7201 BEGA angular contact bearings
- Design Type: Block design for robust integration
- Article Type: Housing unit for locating arrangement
- Material: Burnished steel construction for durability and precision
- Preload: With preload for enhanced rigidity and precision
- Seal: With seal - two radial shaft seals included for protection
- Lubrication: Greased bearings for extended operational life
- Included Components: 1x CN70-12 nut for secure assembly
Performance Features:
- Angular Contact Bearings: The dual 7201 BEGA bearing configuration provides superior axial load capacity and positional accuracy, making it ideal for locating-side support in precision applications
- Preloaded Design: Factory-applied preload eliminates play and minimizes deflection, ensuring consistent positioning and extended bearing life
- Sealed Configuration: Dual radial seals protect the bearing assembly from contaminants while maintaining low operating friction
- Greased Operation: Pre-lubricated bearings reduce maintenance requirements and ensure reliable long-term performance
- Block Design: Compact, rigid housing optimizes space utilization while providing secure mounting in demanding industrial environments
Typical Applications:
- CNC machine tools and precision machining centers
- Industrial automation equipment requiring fixed-point bearing support
- Semiconductor and electronics manufacturing systems
- Medical device machinery with high-precision requirements
- Ball screw drive systems where fixed axial positioning and load capacity are critical
- High-speed spindle systems and precision linear motion applications
The PLBU20 CN is particularly suited for applications where the locating bearing unit must provide maximum rigidity and axial load capacity. When paired with a complementary non-locating floating bearing unit, it forms a complete precision ball screw support system capable of delivering exceptional performance in demanding manufacturing and automation environments.
