Low Assembly EGW-CA/SA Series Linear Guideway

Main Technical Parameters and Design
1. Design:
Increasing the width to compensate for the structural strength and torque capacity potentially lost due to reduced height is a classic application of the "area moment of inertia" principle in engineering.
2. Performance Characteristics:
At the same height specifications (e.g., 15mm, 20mm), the EGW's guide rail width and slider width are both greater than the EGH.
Typically provides medium preload levels to ensure high rigidity even in compact spaces.
3. Key Selection Criteria:
Height is a hard constraint: Confirm the maximum total installation height allowed by the equipment.
Width is an opportunity:  Given the height constraints, choose the widest possible EGW specification to obtain better load capacity and rigidity.
Comparative verification: Comparing the EGW's width-load curve with the EGH's height-load curve often reveals that EGW performs better at the same height.

Applications
The EGW-CA/SA series is an ideal choice for high-end applications where space and performance requirements are contradictory:
High-end semiconductor and panel equipment: Motion axes in photolithography machines and mass transfer equipment where height is limited but extremely high load and precision are required.
Heavy-duty medical imaging equipment: Precision slip rings or patient platforms in CT machines and MRI scanners that require large-range, stable, and low-profile movement.
Precision machining and inspection: Dual-exchange worktables in horizontal machining centers, and mobile bases for large precision optical inspection instruments.
Specialized automation: Automated assembly and testing platforms inside spacecraft or large vehicles where space is extremely valuable. The Low Assembly EGW-CA/SA Series Linear Guideway is a highly strategic product.  It's not simply a variation in size, but a precisely engineered response to specific pain points in high-end markets. Choosing the EGW series means your equipment design faces the dual challenges of limited space and demanding performance requirements, and you've successfully found the optimal solution by selecting the most suitable technology. It represents the cutting edge of linear guidance technology, moving towards higher integration and better space utilization.

Cyclone Milling Machines LWN160-6000mm Leistritz Cyclone milling machines imported directly from Germany, the ball screw shaft precision can be C3, C5, and C7 the max length can be 7000mm

Rolled Thread CNC Machines ST-20.2 and ST-347.7 rolled thread ball screw machines from TaiWan. The ball screw shaft precision can be C7 - C10

Ball Screw Assembly Workshop We conduct nut assembly in a constant temperature workshop,  all workers having decades of work experience and zero clearance between the screw and nut.

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.
