①HIWIN RGH20CA Linear Guideway Hiwin Roller Guide Rail Blocks

The HIWIN RGH20CA Linear Guideway represents the pinnacle of heavy-duty linear motion technology, combining advanced roller-type guidance with superior load-bearing capacity for industrial applications where extreme rigidity and precision are paramount. Engineered with oversized cylindrical rollers and reinforced raceways, this robust system delivers up to higher rigidity compared to conventional ball-type guides, making it ideal for high-performance CNC gantry mills, heavy cutting machines, and precision automation equipment handling substantial moment loads. The RGH20CA's unique roller arrangement achieves near-zero backlash operation while maintaining smooth motion characteristics, even when supporting multi-ton workpieces or enduring intense machining vibrations. Its hardened and precision-ground components feature optimized contact angles that distribute stress evenly across the bearing surfaces, dramatically extending service life in 24/7 production environments. The guideway incorporates HIWIN's proprietary sealing technology with multi-layer wiper designs that effectively exclude chips, coolant, and abrasive particles without increasing friction resistance. With its oversized flange dimensions and reinforced mounting structure, the RGH20CA provides exceptional resistance to deflection during heavy cutting operations, ensuring consistent machining accuracy across large work envelopes. The system's preload adjustability allows fine-tuning for specific application requirements, from high-speed positioning to ultra-precise finishing operations. Whether deployed in aerospace structural component manufacturing, heavy mold and die production, or precision grinding machine retrofits, the HIWIN RGH20CA Roller Guideway System sets new standards for durability and precision in the most demanding industrial environments, delivering unmatched performance where conventional linear guides would compromise accuracy or require frequent maintenance.

1.Rolling circulation system: Block, rail, end cap, Circulation path, rollers
2.Lubrication system: Grease nipple and piping joint
3.Dust protection system: End seal, bottom seal,bolt cap, double seals and scraper.
⑤Features of RG series
The new RG series from HIWIN features a roller as the rolling element instead of steel balls. The roller series offers super high rigidity and very high load capacities. The RG series is designed with a 45-degree angle of contact. Elastic deformation of the linear contact surface, during load, is greatly reduced thereby offering greater rigidity and higher load capacities in all 4 load directions.The RG series linear guideway offers high performance for high-precisionmanufacturing and achieving longer service life.
1. Optimal design
FEM analysis was performed to determine the optimal structure of the block and the rail. The unique design of the circulation path allows the RG series linear guideway to offer smoother linear motion.
2.Super high rigidity
The RG series is a type of linear guideway that uses rollers as the rolling elements. Rollers have a greater contact area thanballs so that the roller guideway features higher load capacityand greater rigidity. The figure shows the rigidity of a roller and a ball with equal volume.
3. Super high load capacity
With the four rows of rollers arranged at a contact angle of 45-degrees, the RG series linear guideway has equal load ratings in the radial, reverse radial and lateral directions.The RG series has a higher load capacity in a smaller size than conventional, ball-type linear guideways.
4. Operating life increased
Compare with the ball element, the contact pressure of rolling element is distributed on the line region. Therefore,stress concentration was reduced siginificantly and the RG series offers longer running life. The nominal life of RG seriescan be calculated by using Eq.
