Technical Parameter Details

Structural Specifications Analysis
Model Explanation: LMHC-L-UU
LM: Linear Bearing Series
H: Double-edged structure (special anti-rotation design)
C: Central/Center Flange position
L: Extended type (core advantage multiplier)
UU: Double-ended contact seal

Performance Triple Advantage
1. Extended Type (L) Core Value
Increased Rigidity: 40-60% higher rigidity than standard type, significantly reduced deformation
Extended Lifespan: Better load distribution, theoretical lifespan increased by more than 50%
Smooth Operation: Extended guidance, strong resistance to eccentric loads, no jamming or vibration
2. Double-edged (H) Space Advantage
Compact Arrangement: Supports minimum bearing center distance design
Reliable Anti-rotation: Mechanical edge anti-rotation, no risk of loosening
Installation Datum: The edge plane can be used as a machining and assembly datum surface
3. Centralized (C) Mechanical Advantage
Automatic Alignment: Load is automatically and evenly distributed to both sides
Zero Additional Bending Moment: Eliminates eccentric load deformation of the mounting plate from the source
Anti-overturning: Increased resistance to overturning moment by 2-3 times

Selection Decision Matrix

Key Installation Steps
1. Installation Surface Pre-treatment
Flatness requirement: ≤0.02mm/100mm
Double-edged groove machining: Width tolerance H7, depth control ±0.1mm
Surface treatment: Anodizing or chrome plating recommended for corrosion resistance
2. Alignment and Assembly Process
Use the double-edged plane for initial positioning
Pre-tighten all bolts to 30% torque
Measure the height difference of the two cantilevered ends using a dial indicator, adjust to ≤0.01mm
Tighten to full torque in a cross-pattern sequence
3. Running Verification Points
Manually push under no load, feel for uniform damping throughout the entire range
Load 50% of the rated load, check for smooth operation
Monitor temperature rise during long-term operation, should be ≤40℃ above ambient temperature

The LMHC-L-UU center-mount double-cut linear bearing is not a general-purpose part, but an elegant solution to specific engineering problems.
Its existence answers three core questions:
1. When space is at a premium, how to avoid sacrificing performance?
→ Answer: Double-edged design, minimum radial footprint
2. When absolute anti-rotation reliability is required, how to avoid complex structures?
→ Answer: Mechanical edge anti-rotation, simple and reliable
3. When long life and high rigidity are required, how to achieve this in a compact space? → Answer: Extended design, enhanced rigidity and lifespan.
Profile of engineers who choose LMHC-L-UU:
