Overview
The Rexroth R103883020 LSAOE-B-30-DD is a precision linear motion bearing set designed for applications requiring smooth, accurate linear travel. This unit combines a lightweight aluminum housing with Super B linear bushings and delivers consistent performance across industrial automation, machine tools, and positioning systems. The open, adjustable design allows technicians to fine-tune radial clearance and adapt to application-specific requirements without extensive modifications.
Key Features
- Super B Linear Bushings: Precision ball bearings optimized for repeatability and low breakaway force
- 30 mm Shaft Diameter: Designed for mid-range load applications requiring rigidity without excessive bulk
- Zero-Clearance Configuration: Ships pre-tensioned and ready to install, with adjustable clearance via integral screw
- Aluminum Housing: Lightweight construction reduces inertial load while maintaining structural integrity
- Integrated Wiper Seals: Dual-sided seals protect bearing elements from contamination and extend service life
- Operating Temperature Range: -20°C to 80°C for use in controlled industrial environments
