Within the low-profile linear guide family, selecting the correct block geometry is essential for optimizing machine footprint and mounting efficiency.
1. EGH Series: Compact Square Type
The EGH features a high, narrow, box-like profile designed specifically for lateral space optimization.
Mounting Interface: Utilizes four tapped holes on the top surface. Mounting is typically achieved by passing bolts through the carriage plate and threading them directly into the block.
Key Advantage: Lateral Space Efficiency. By eliminating side flanges, the EGH offers the narrowest footprint in its class.
Ideal Applications: Best suited for environments with strict width constraints or applications where multiple rails must be mounted in close proximity within a narrow channel.
2. EGW Series: Versatile Flange Type
The EGW features extended lateral flanges (wings) that provide a broadened mounting base and increased installation flexibility.
Mounting Interface: The widened flange design allows for bi-directional mounting. Depending on the specific sub-model, the block can be secured from the top down (threading into the flange) or from the bottom up (passing bolts through the flange into a threaded carriage).
Key Advantage: Enhanced Stability and Versatility. The wider stance increases the block's resistance to lateral moment loads (MR or rolling moments) and provides a more stable platform for the carriage.
Ideal Applications: Perfect for assemblies requiring bottom-up mounting or systems subjected to moderate twisting forces and vibrations.
