LBCR25D Ewellix Closed Linear Ball Bearing 25x40x58mm
The LBCR25D Ewellix Closed Linear Ball Bearing is a precision-engineered ball bushing designed to deliver smooth, reliable linear motion in demanding industrial applications. Manufactured by Ewellix, this closed linear bearing combines exceptional load-carrying capacity with a robust design suitable for heavy-duty machinery and equipment requiring minimal maintenance.
Product Overview
The LBCR25D features a cage and raceway segment design that precisely guides the balls along the bearing's track, ensuring consistent performance and extended service life. With an inside diameter of 25mm, outside diameter of 40mm, and width of 58mm, this mid-sized bearing offers an excellent balance between load capacity and compact form factor, making it ideal for space-conscious installations.
Key Features
- Heavy Load Capacity: Engineered to handle significant loads thanks to exceptionally long track length and machined raceway osculation
- Closed Housing Configuration: Factory-sealed design that determines operating clearance through housing bore tolerance, simplifying installation and ensuring consistent performance
- Open Bearing Design: Allows for greasing and maintenance accessibility throughout the bearing's operational life
- Robust Construction: Built with steel and plastic components for durability and reliable performance in demanding environments
- Compact Dimensions: 25mm inside diameter, 40mm outside diameter, 58mm width for space-efficient installations
- Wide Temperature Range: Operates effectively from -30°C to +80°C, suitable for diverse environmental conditions
- No Misalignment Compensation: Standard series design for applications requiring precise axial alignment
- Compatible with Standard Linear Shaft Systems: Integrates seamlessly with conventional linear motion setups
Design & Performance
The cage and raceway segment design maximizes load distribution across the ball set, enabling optimal performance in heavy-duty applications. The closed housing configuration ensures that operating clearance is determined by the housing bore tolerance, streamlining installation and maintenance procedures. As with all LBCR ball bushings, proper axial positioning via grease fitting or fixation pin is required during installation to ensure optimal performance and longevity.
Typical Applications
The LBCR25D is well-suited for a wide range of industrial applications including:
- Precision automation and manufacturing equipment
- Industrial machinery and conveyor systems
- Medical and laboratory instruments
- Printing and packaging machinery
- Heavy-duty positioning systems
- Machinery requiring smooth linear motion with minimal friction
