Introduction
The Oval type flanged linear bearing is a core component of high-precision linear motion systems. With an extended design (length increased by 20%-50% compared to standard models) and an elliptical flange structure, it can be directly fixed with bolts, significantly enhancing installation stability and load capacity. It is suitable for high-load, long-stroke, and high-precision automation equipment, such as industrial robots, medical machinery, and semiconductor manufacturing.
product highlights
1. High Load Capacity
The extended design increases the number of balls, tripling dynamic load capacity and extending lifespan by 27 times
2. High Precision & Low Friction
Precision grinding ensures repeat positioning accuracy of ±0.01mm, with a friction coefficient as low as 0.001-0.003 for smooth, Smooth - free operation
3. Impact Resistance & Corrosion Resistance
Bearing steel (GCr15) with nickel-plated/oxidized surface, suitable for harsh environments like high temperatures and dust
4. Easy Installation & Maintenance
Elliptical flange design saves space, supports multiple lubrication methods (drip, bath, spray, etc.), and facilitates maintenance

Application Scenarios
Installation Guide
1. Cleaning & Lubrication:
Oval type flanged linear bearing Remove anti-rust oil with cleaning oil before installation, apply low-viscosity lubricant (e.g., ISO VG32)
2. Positioning & Fixing:
Tighten bolts from the center to the sides, use a torque wrench for uniform torque
3. Alignment & Centering:
Self-aligning design compensates for installation errors to ensure concentricity

Selection Tips
Load Calculation: Select models based on maximum static/dynamic loads (refer to parameter table).
Environmental Compatibility:
High-temperature: Choose stainless steel + high-temperature grease521.
Dust: Select sealed bearings (e.g., LMH…UU-MX series)
Precision Matching: Opt for ±0.005mm class for precision equipment
FAQ
Q: How to select the appropriate LMH bearing model for my equipment?
A:Focus on three key parameters:
Load Capacity: Based on the equipment's maximum static load (refer to "Static Load" in the parameter table) and dynamic load during operation (refer to "Dynamic Load"), ensure the selected model's load threshold is 1.5-2 times higher than the actual load.
Precision Class: Choose the standard ±0.01mm class for general equipment (e.g., automated production lines); select the precision ±0.005mm class for precision instruments (e.g., semiconductor lithography machines).
Environmental Adaptation: Use stainless steel (SUS440C) for high-temperature scenarios, the sealed LMH…UU-MX series for dusty environments, and nickel-plated surfaces for high-humidity conditions.
Q: What installation details should be noted to avoid precision deviation?
A:Cleaning & Lubrication: Remove anti-rust oil and impurities from the bearing and mounting surface with anhydrous alcohol or special cleaning oil before installation. Apply a proper amount of low-viscosity lubricant (e.g., ISO VG32) to prevent jamming caused by foreign objects.
Bolt Fixing: Use a torque wrench to tighten bolts 2-3 times in the order from the center to the sides for uniform torque (specific torque values refer to the product manual, e.g., 8-10N·m for LMH12-LUU).
Shaft-Bearing Alignment: Use the bearing's self-aligning design to compensate for minor installation errors (allowable tilt angle ≤1°), but ensure the concentricity error between the shaft and bearing is less than 1/2 of the precision class (e.g., ≤0.0025mm for the precision class).
