RG Series -High Rigidity Roller Type Linear Guideway 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 areatly reduced thereby offering greater rigidity and higher load capacities in all 4 load directions.The RG series linear guideway offers high performance for high-precision manufacturing and achievng longer service life. Proper Installation of Linear Guides In this section, we’ll explain in detail how to install THK linear guide in linear type applications. Step 1: Before mounting the linear guides, a highly recommended advice is to clean up all rough edges and contaminate objects. Important: Datum lines of linear guides are normally composed of antirust. So, brush the antirust with a cleanser before positioning. Spraying some low coherence grease can preserve the datum plane. Step 2: Place the linear guide on the base and secure it with the drive screw or other appliances, so it sits properly on the datum line nicely. Important: Don’t forget to examine the adjustment of the screw holes before tightening them. Tightening the screw forcefully can unalign the screw holes, which influences the accuracy and quality due to offset. Step 3: Sequentially fasten the bolts to make the rail more steady. Push the track against the datum line gently to improve the connection between them. Step 4: Through a torque wrench, tighten the bolts from the centre to both edges. Step 5: Repeat similar strides for installing the auxiliary rail and then install the slides on the rail independently. Don’t forget to gather all adornments, like lubricant fitting, grease fitting and seals in this stage. Otherwise, later on, it gets hard to gather the adornments because of less space. Step 6: Locate the table smoothly on the slides on both main and subsidiary rails. Step 7: Tighten the perpendicular thrust screw to settle the table and attach the table screws in the sequence.

• 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
• 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 than balls so that the roller guideway features higher load capacity and greater rigidity. The figure shows the rigidity of a roller and a ball with equal volume
• 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
• 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 series can be calculated by using Eq
• Rails available:If need rails please send us the length of the rail
