Ambient Operating Temp. Dg6 Bushing Body has four flat sides machined internally. Dg6 Retainer Made from one-piece casting of super engineered plastic. d1 Through Hole High accuracy needle rollers are arranged in four directions against the square shafts. Shafts / Bushings are designed to be 1 ~ 6µm preloaded. Widely used in parts of semiconductor, liquid crystal manufacturing equipment and inspection device, lift / slide stages, robotic systems, press machines and transfer mechanism as the guide with high rigidity, straightness and high speed. Capable of torque loading without rotation due to square cross section with low yawing and pitching, maintaining smooth rotation and stable accuracy. 10 12 16 Part Number RGPFN10 8 - D1 L1 T H W 8 7.8 2.5 M3x 6 16 25 5 32 17 10.8 3.4 24 15 1.5 4.8 16 60~80 30 8 11.0 4.2 M5x10 24 36 7 43 25 15.0 4.5 33 19 2 4.8 20 90~120 40 10 14.6 5 M6x12 31 50 7 50 32 18.6 5.5 40 30 2 6.8 24 100~130 50 10 18.9 6.8 M8x16 32 60 7 55 33 22.9 6.6 43 33 2 6.8 24 L .88 ENon-Returnable P d1 M Part Number Type D 6 10 RGPFN 12 16 6 10 RGPFT 12 16 6 10 RGPFS 12 16 P L 10mm Increment 50~70 60~80 90~120 100~130 50~70 60~80 90~120 100~130 50~70 60~80 90~120 100~130 d A R Retainer L2 d2 (Length) Needle Quantity 20 60 B Bushing 50~70 −0.004 −0.012 −0.005 −0.014 -0.006 -0.017 Shafts Unit Price Qty. 1~10 11~19 257.60 245.30 259.30 247.20 268.10 255.70 274.00 262.50 263.30 251.10 265.10 253.00 273.80 261.50 279.70 267.10 266.70 254.60 269.70 256.50 277.30 265.00 283.20 270.60 .87 EFor larger quantity orders "Days to Ship" may differ from published catalog term.D P Lift Stage Swiveling Arm Slide Stage QCautions 323 -Administer lubrication maintenance as needed. -When designing, position the bushing where the retainer does not fall out from the bushing at stroke ends. -As the preload is still applied when inserting retainers, assemble and fit carefully in order not to apply any off-center insertion force as that may cause the damage to the retainers as well as damages on the rolling surfaces. -Protect it with covers if any foreign objects or dust may adhere to the rolling surfaces. -Avoid using in high temperature environments, keep below 80°C. -Do not cold shrink fit the bushings and shafts. Residual austenite will transform into martensite and will expand inner / outer dimension of bushings and shafts, rendering them unusable. 324
