5 TUTORS Rotary ctuators are constructed with the finest materials for each component! 1 Floating Pistons: Solid aluminum alloy, lightweight for low inertia, yet strong. Provide excellent wear characteristics against the hard coated tube I.. 2 Seals: Lip type, pressure sensitive nitrile seals are wear compensating for long service life and minimum friction. 1 2 ctuator ody: Precision machined from 6061-T6, 40,000 PSI minimum yield aluminum alloy for strength. The entire body is then hard-anodized for maximum wear and corrosion resistance. 4 rease Fitting: asy access for additional lubrication. Single rack located on top; double located on top and bottom Retainers: luminum plates are located on the front and rear of the actuator body to ensure positive retention of the pinion/shaft/bearing assembly. 6 Tie Rods: Stress-proof steel to maintain compression on the tube end seals. 6 Single Rack Shown Rotation djustment (optional): Up to 0 angle. 8 nd aps: Machined from 6061-T6 solid aluminum bar that is anodized for corrosion resistance rotations are standard and available in single or double rack models. Other rotations available up to Tube: 606-T82 aluminum alloy which is ideally suited for air service. The tube is clear anodized on the O.. and hard anodic coated on the I.. which results in a smooth, file hard (60R), corrosion and score resistant surface finish. 9 Rack: round and polished stress-proof steel. 10 Shaft earings: Sealed, single row ball bearings provide exceptional shaft stability with a low coefficient of friction. 11 Pinion and Output Shaft: Manufactured from high strength steel for maximum strength and endurance. keyed output shaft is standard with other shaft options available.

Use of external stops, cushions, or other deceleration devices will ensure maximum performance and actuator life.

The design also provides exceptionally fast out of cushion rotation reversal. djustment Needle ushion ushion esign 1-1/2" or 2-1/2" ore isplacement Load earing apacity Unit Weights isplacement istance for ach egree xial Load Radial Load etween Unit Weight Unit Weight Unit Weight dd for ouble of Rotation earing apacity earing apacity earings Output Shaft ore Size Inch (mm ) lbs (Kg) lbs (Kg) Inch (mm) lbs (Kg) lbs (Kg) lbs (Kg) lbs (Kg) 1-1/8" Single Rack.0108 (177) 100 (45) 200 (91) 1.8 (5).5 (1.59).75 (1.70) 4.25 (1.9).06 (.0) 1-1/8" ouble Rack.0216 (54) 100 (45) 200 (91) 1.8 (5) 6 (2.72) 7 (.18) 8.5 (.86).06 (.0) 1-1/2" Single Rack.0270 (44) 225 (102) 450 (204) 1.56 (40) 6.75 (.06) 7.5 (.41) 9 (4.09).44 (.16) 1-1/2" ouble Rack.0540 (885) 225 (102) 450 (204) 1.56 (40) 10.5 (4.77) (5.79) (7.8).44 (.16) 2" Single Rack.0760 (1254) 500 (227) 1000 (454) 2.28 (58) 18 (8.17) 19.5 (8.85) 21 (9.5).656 (.0) 2" ouble Rack.1520 (2491) 500 (227) 1000 (454) 2.28 (58) 22 (9.98) 24 (10.90) 27 (12.26).656 (.0) 2-1/2" Single Rack.1200 (1966) 500 (227) 1000 (454) 2.28 (58) 18.5 (8.40) 20 (9.08) 22 (9.99).656 (.0) 2-1/2" ouble Rack.2400 (9) 500 (227) 1000 (454) 2.28 (58) 22.5 (10.22) 24.5 (11.12) 27.5 (12.49).656 (.0) Theoretical Torque Output in Inch-pounds per PSI (Newton-meters per ar) Inch- (Newton- PSI (ar) pounds meters ore Size 40 (2.8) 60 (4.1) 80 (5.5) 90 (6.2) 100 (6.9) 125 (8.6) 150 (10.) 200 (1.8) 250 (17.2) 400 (27.6) per PSI per ar) 1-1/8" Single Rack 25 (2.8) 7 (4.2) 50 (5.6) 56 (6.) 62 (7.0) 78 (8.8) 9 (17.5) 124 (10.5) 156 (17.6) 249 (28.1).6 (.59) 1-1/8" ouble Rack ) 75 (8.4) 100 (11.) 112 (12.7) 124 (14.1) 155 (17.6) 187 (21.1) 249 (28.1) 11 (5.1) 498 (56.2) 1.2 (1.97) 1-1/2" Single Rack 62 (7.0) 9 (10.4) 124 (14.0) 19 (15.7) 155 (17.5) 194 (21.9) 22 (26.2) 10 (5.0) 87 (4.7) 620 (70.0).6 (2.62) 1-1/2" ouble Rack 12 (14.0) 186 (21.0) 248 (28.0) 279 (1.5) 10 (5.0) 87 (4.8) 465 (52.5) 620 (70.0) 774 (87.5) 129 (140.0).2 (5.24) 2" Single Rack 175 (19.9) 264 (29.8) 52 (9.7) 96 (44.7) 440 (49.7) 550 (62.1) 660 (74.4) 879 (99.) 1099 (124.1) 1758 (198.6) 4.4 (7.21) 2" ouble Rack 52 (9.7) 528 (59.6) 70 (79.5) 791 (89.4) 879 (99.) 1099 (124.1) 119 (149.0) 1758 (198.6) 2198 (248.) 517 (97.2) 8.8 (14.41) 2-1/2" Single Rack 275 (1.0) 412 (46.6) 550 (62.1) 619 (69.9) 687 (77.7) 860 (97.1) 101 (116.5) 175 (155.) 1719 (194.1) 2750 (10.6) 6.9 (11.0) 2-1/2" ouble Rack 550 (62.1) 825 (9.2) 1100 (124.2) 127 (19.8) 175 (155.) 1719 (194.1) 2062 (22.9) 2750 (10.6) 47 (88.2) 5500 (621.2) 1.8 (22.60) NOT: ir/oil Tandem and Multiple Position Rotary ctuators utilize a double rack configuration; however, the torque output of a Single Rack unit apply. educt 10% from torque output for frictional loss. educt 20% for frictional loss on all ir/oil Tandem Rotary ctuators.
