1.Core advantages
Ultra-high precision：
Repeat positioning accuracy can reach ±0.5μm (ultra-precision grade)
Eliminate the creeping phenomenon (Stick-slip effect) of traditional sliding guides
Application case: Semiconductor lithography machine workbench positioning
Low friction and high efficiency：
Friction coefficient is only 0.001-0.005 (1/50 of sliding guides)
Drive power is saved by more than 30%
Data comparison: Servo motor power can be reduced by 200W under the same load
Long life design：
Theoretical life>10,000km (under normal maintenance conditions)
Wear only occurs on the rolling element, and the replacement cost is lower than that of the integral guide
High rigidity load bearing：
Four-way equal load design (radial/reverse radial/lateral/torque)
Roller type guide static stiffness can reach 50 0N/μm
Modular installation：
Adjustable preload (P0-P4 five-level preload)
Separate structure of guide rail and slider, easy maintenance
II. Inherent limitations
Weak impact resistance
Instantaneous impact load needs to be less than 3 times the rated load (comparison: sliding guide rails can withstand 5-8 times)
Solution: It is recommended to add hydraulic buffers in heavy-duty situations
Environmental sensitivity
Dust environment requires IP54 or above protection level
Humid environment may cause electrochemical corrosion (stainless steel model cost increases by 40%)
High-speed vibration problem
High-frequency micro-vibration may occur when exceeding 5m/s (DN value limit)
Optimization solution: Use ceramic rolling elements or hydrostatic guide rails
Cost factors
The price is 2-3 times that of sliding guide rails (but the comprehensive life cycle cost is 30% lower)
III. Comparison with alternative technologies
iv.Selection and Pitfall Avoidance Guide
Scenarios not suitable for linear guides:
Forging machine tools (impact acceleration > 10g)
Electroplating workshop (strong acid and alkali environment)
Open-air construction machinery (areas prone to sandstorms)
Recommended use scenarios:
High-speed PCB drilling machine (micron-level positioning)
Medical robot (clean room environment)
Photovoltaic silicon wafer sorting equipment (24-hour continuous operation)
