①HIWIN RGH35CA Linear Guideway For Heavy Duty Cutting Machines
The HIWIN RGH35CA Linear Guideway sets the benchmark for reliability in heavy-duty cutting machines, where extreme forces and continuous operation demand unwavering precision and structural integrity. Engineered to withstand the punishing conditions of high-power machining, this roller-type guideway system delivers exceptional vibration resistance and load-bearing capacity—critical for maintaining cutting accuracy when processing hardened steels, titanium alloys, or other challenging materials. The RGH35CA's robust construction combats the deflection and micro-movements that compromise surface quality in deep-cut milling, heavy boring, and aggressive turning applications. Its advanced roller technology distributes cutting forces evenly across hardened raceways, preventing localized wear while ensuring smooth axis movement even under maximum chip loads.
The guideway's reinforced housing and oversized rolling elements absorb the shocks and harmonics generated during interrupted cuts or high-feed operations, protecting spindle integrity and prolonging tool life. A multi-stage sealing system shields critical components from the abrasive metal particles and high-pressure coolant typical in cutting environments, while engineered lubrication channels maintain optimal performance during extended production runs. Designed for integration into gantry mills, horizontal machining centers, and large-scale CNC lathes, the RGH35CA excels in applications where traditional guides would falter—maintaining positioning accuracy through marathon cutting sessions that push machinery to its limits. By combining industrial-grade durability with precision-ground motion surfaces, this linear guideway enables manufacturers to pursue heavier cuts, tighter tolerances, and uninterrupted production cycles with confidence. For heavy cutting applications where performance cannot be compromised, the HIWIN RGH35CA provides the unshakable foundation that transforms machine potential into consistent, high-quality results—shift after demanding shift.

③Model Number of RG Series
④Construction of RG Series
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.
