Main Technical Parameters and Design
1. Compact Design: The slider's shape is optimized to the extreme within the minimum space required for ball circulation and sealing, achieving minimal height.
2. Performance Balance: Using a high-rigidity cage and optimized ball contact angle, the system's load capacity and rigidity are maintained as much as possible while reducing height.
3. Sealing and Lubrication: Equipped with compact end seals and potentially integrated grease reservoirs, ensuring good dust protection and long-lasting lubrication even in confined spaces.
4. Selection Considerations:
Confirm maximum height: Clearly define the maximum allowable installation height of the equipment; this is the first constraint for selection.
Calculate load: Under the premise of meeting height requirements, select the specifications that meet the load and lifespan requirements.
Choose mounting type: Select the CA type (side flange mounting) or SA type (top mounting) according to the equipment structure.
Applications
The EGH-CA/SA series is the perfect partner for the following space-sensitive equipment:
Precision electronic manufacturing: X-Y motion platforms for SMT placement machines, chip packaging machines, and PCB drilling machines.
Medical devices and laboratory equipment: Automated analyzers, DNA sequencers, and automatic microscope platforms.
Small automation: Desktop robots, small linear motor modules, and guiding mechanisms for precision dispensing machines.
Semiconductor and panel industry: Wafer handling robots, and space-constrained linear axes in LCD panel inspection equipment.
The EGH-CA/SA series low-profile linear guide is the culmination of engineering ingenuity in "space-constrained" design environments. It proves that high-performance linear guidance does not necessarily have to come at the cost of occupying a large amount of space. Choosing the EGH series means you can integrate a reliable, precise, and efficient linear motion core into your equipment, even within strict size constraints. It's a key component for achieving miniaturization, integration, and performance balance in your equipment.

Ball Screw Assembly Workshop
One ball screw shaft matches one ball screw nut. Because each ball screw shaft has a very tiny different tolerance. There are dozens of different ball sizes for different screw shaft. Our ball screw shaft and nut can be interchanged with the Taiwan TBI ball screw shaft and nut very well. |
