FLBU40 CN Ewellix Bearing unit
The FLBU40 CN Ewellix Bearing Unit is a precision housing unit designed for fixed-side (locating) support in ball screw drive systems. This flange-mounted unit is engineered to provide rigid axial positioning and load support, making it an essential component when paired with a floating-side bearing unit as part of a complete ball screw support system.
Key Specifications:
- Inner Dimension: 40mm shaft diameter
- Bearing Configuration: 2x 7206 BEGA angular contact bearings
- Design Type: Housing unit for locating (fixed-side) arrangement
- Material: Burnished steel construction for durability and precision
- Mount Style: Flange design for secure, rigid installation
- Preload: With preload - optimized for fixed-side support and axial load capacity
- Seal Type: With seal - includes two radial shaft seals for contamination protection and lubrication retention
- Lubrication: Pre-greased for extended operation and simplified maintenance
- Scope of Delivery: Includes 1x CN70-30 nut and two seals for radial shaft retention
Design Features:
As the fixed-side (locating) component of a ball screw support system, the FLBU40 CN utilizes dual angular contact bearings (7206 BEGA) to provide exceptional axial stiffness and load capacity while precisely positioning the shaft. The preload configuration ensures minimal backlash and enhanced positional accuracy, making it ideal for applications demanding high precision and repeatability. The sealed, greased design enables long-term operation in various industrial environments without frequent maintenance intervention.
Applications:
Ideal for high-precision CNC machine tools, semiconductor manufacturing equipment, medical device machinery, and industrial automation systems requiring reliable fixed-side bearing support. The FLBU40 CN is particularly well-suited for ball screw systems operating in demanding environments where thermal stability, axial load capacity, and long service life are critical requirements.
