Roller Type RGH-CA/HA Series Linear Guideway

Main Technical Parameters and Design
1. Roller Circulation System:  Utilizes a precision roller retainer to ensure smooth, synchronous circulation of each roller, preventing collisions and friction, maintaining low noise and low temperature rise even at high speeds.
2. Accuracy Class: Offers top-tier accuracy options from precision grade (P) to ultra-precision grade (UP), ensuring that heavy loads and high precision are not mutually exclusive.
3. Preload and Rigidity Configuration: Typically comes standard with heavy preload (C3) to enhance system rigidity; some models offer an ultra-heavy preload (C5) option.
4. Sealing Technology: Equipped with multiple seals and heavy-duty scrapers to prevent large particle chips and dust generated in heavy-load environments from entering the raceway.

Applications
The Roller Type RGH-CA/HA Series Linear Guideway is the ideal choice for the following top-tier heavy-duty, high-precision equipment:
Ultra-heavy-duty CNC machine tools: Core linear axes of large gantry five-axis machining centers, heavy-duty floor-type boring and milling machines, and guideway grinding machines.
High-precision heavy equipment: Large coordinate measuring machines, ultra-precision optical processing machine tools, and heavy-duty presses for semiconductor packaging.
Energy and heavy industry: Wind power gearbox processing equipment, large diesel engine cylinder block processing lines, and precision guidance for heavy presses.
High-end scientific research equipment: Load-bearing and motion mechanisms for synchrotron radiation sources and spacecraft component testing platforms.

The Roller Type RGH-CA/HA Series Linear Guideway is a masterpiece that pushes the physical limits of linear motion technology. It abandons the pursuit of universal applicability through extreme speed and low friction, instead pushing load capacity, rigidity, and stability to the extreme. It is not merely a component, but a decisive force in ensuring high-performance, high-precision machining of heavy equipment.

_{Production Capacity}

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.
