LBCR25D-LS Ewellix Closed Linear Ball Bearing 25x40x58mm
The LBCR25D-LS Ewellix Closed Linear Ball Bearing is a precision-engineered linear ball bearing designed to deliver smooth, reliable motion in demanding industrial applications. Manufactured by Ewellix, this closed bearing combines efficient load-carrying capacity with a robust design optimized for heavy-duty performance.
Product Overview
This linear ball bearing 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, the LBCR25D-LS delivers exceptional load-carrying capability in a compact form factor suitable for a wide range of industrial environments.
Key Features
- Heavy Load Capacity: Engineered to handle significant loads with an exceptionally long track length and machined raceway osculation for superior load distribution
- Closed Housing Configuration: Factory-sealed design with contact seal on one side to eliminate the need for external housing adjustments and reduce contamination
- Robust Construction: Built with steel and plastic components for durability and reliable long-term performance
- Enhanced Raceway Design: Optimized raceway segments positioned for maximum load-carrying capacity
- Wide Temperature Range: Operates effectively from -30°C to +80°C, suitable for diverse environmental conditions
- Standard Series Configuration: Compatible with both closed and adjustable housing installations for flexible application design
- No Misalignment Compensation: Designed for applications requiring precise axial alignment
Design & Construction
- Comprises a cage and raceway segments to guide balls with precision
- Features contact seal on one side for enhanced protection against contamination while maintaining accessibility
- Compact dimensions: 25mm inside diameter, 40mm outside diameter, 58mm width
- Must be positioned axially via grease fitting or fixation pin for proper alignment
Installation & Operation
- When mounted in closed housings, operating clearance is determined by housing bore tolerance
- When mounted in slotted housings, can be adjusted to provide either operating clearance or pre-load depending on application requirements
- Sealed design reduces maintenance requirements and extends bearing life
Applications
The LBCR25D-LS is ideal for machinery and equipment requiring smooth linear motion with reliable heavy-load performance, including precision machinery, automation equipment, industrial automation systems, material handling equipment, and manufacturing automation applications.
