①HIWIN RGH45HA Linear Guideway 45mm Hiwin Rail For Plano Millers
The HIWIN RGH45HA Linear Guideway sets a new standard for precision and durability in plano millers, where massive workpieces and aggressive cutting forces demand unwavering stability and vibration-free motion. Engineered specifically for the rigorous requirements of large-scale milling operations, this 45mm roller-type guideway delivers exceptional load capacity to maintain alignment accuracy when machining castings, forgings, and structural components that push the limits of conventional milling equipment. The RGH45HA's reinforced construction combats the deflection and chatter common in heavy face milling applications, ensuring consistent surface finish quality across expansive work tables. Its optimized roller configuration distributes the tremendous cutting forces encountered during simultaneous multi-axis machining of large dies, molds, and industrial components. The guideway's advanced sealing system provides robust protection against the abrasive metal particles and coolant saturation typical in plano milling environments, while maintaining smooth motion characteristics for precision contouring operations. Thermal-stable design elements minimize the effects of heat buildup during prolonged machining sessions, preserving dimensional accuracy when working with challenging materials like hardened steels or high-temperature alloys. Whether integrated into new machine designs or retrofitted to upgrade existing equipment, the RGH45HA provides the foundation for improved metal removal rates and tighter tolerances in aerospace frame machining, wind energy component production, and heavy industrial manufacturing. By combining industrial-grade construction with precision motion control, this linear guideway enables plano millers to achieve new levels of productivity while maintaining the accuracy required for large-scale precision components - transforming the challenges of heavy milling into measurable competitive advantages for manufacturers tackling the most demanding machining applications.
②Drawing of RGH45HA
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.
