Ultra-compact linear motion solution combining high rigidity with minimal space requirements. Features four-row circular arc groove design for smooth motion and optimized load distribution. The BH suffix indicates medium preload (3-5μm) for vibration resistance in precision applications. Includes corrosion-resistant stainless steel end seals and grease retention features.
- Medical device positioning stages (e.g., DNA sequencers)
- Semiconductor wafer handling robots
- High-speed 3D printer X/Y axes
- Optical inspection equipment slides
- Laboratory automation sample handlers
Installation note:
Requires mounting surface flatness ≤0.02mm/m. Use torque-controlled tightening
(0.8-1.2Nm for M3 screws). Perform initial lubrication with ISO VG15-32 grease
before operation. Avoid side-load impacts exceeding 30% of static rating.
