The hole passes cables, coolants, or long workpieces. A crossed roller bearing supports the hollow shaft directly. The drive uses a roller gear cam or high-torque worm.Heavy Duty Hollow Rotary Tables are specialized pieces of equipment used in various industrial applications to provide precise rotational positioning. These Heavy Duty Hollow Rotary Tables are integral in settings such as machining centers, automated assembly lines, and inspection systems.Here we introduce our Heavy Duty Hollow Rotary Table TMW68 as follows Technical Parameters of High payload Hollow Rotary Actuator:SeriesCAM roller type hollow rotating platformModelTMW68TMW90TMW115TMW215TMW315TMW415PhotoDesign load (kgs)≤80kgs≤280kgs≤500kgs≤1600kgs≤2.5Tons≤4.5TonsMax dia of rotating plate(mm)≤ 500 mm≤ 900 mm≤ 1200mm≤ 2000mm≤ 2500mm≤ 3000mmMotor typePlanetary gear+Servo motorPlanetary gear+Servo motorPlanetary gear+Servo motorPlanetary gear+Servo motorPlanetary gear+Servo motorPlanetary gear+Servo motorMotor in configuration0.4kw/0.75kw80 flange Servo80/130 flange Servo130/180 flange Servo180 flange Servo180 flange ServoReduction ratio of rotating body1:20i1:20i1:20i1:40i1:60i1:60iOverturning moment400 N.m625N.m1028N.m3500N.m14000 N.m30000 N.mAllowable input torque≤30 Nm≤72 Nm≤90 Nm≤500 Nm≤500 Nm≤500 NmRated output torque≤600 N.m≤1440 N.m≤1800 N.m≤20000 N.m≤30000 N.m≤30000 N.mAllowable moment of inertia75N.m220 N.m260 N.m18000 N.m Allowable input speed2000 R/min2000 R/min2000 R/min1200 R/min2000 R/min2000 R/minRepeat positioning accuracy±5 arc-sec±5 arc-sec±5 arc-sec±5 arc-sec±5 arc-sec±5 arc-secPositioning accuracy±10 arc-sec±10 arc-sec±10 arc-sec±10 arc-sec±10 arc-sec±10 arc-secPlatform concentricity0.02mm0.02mm0.02mm0.02mm0.02mm0.02mmPlatform Parallelism0.02mm0.02mm0.02mm0.02mm0.02mm0.02mmAccuracy life20000 ( intermittent motion )Structure typeCam roller+cross roller bearingProtection GradeIP50IP50IP50IP50IP50IP50Weight (kg)16kgs24kgs45kgs120kgs200kgs300kgs OptionsDriver and CableDriver and cable provided if Motor provided by Tallman Robotics Limited (Usually, we configure Delta, Inovance )Face rotating PlateProvided if needed.(Drawing provided by the clients)SensorsPhotoelectric sensor, brackets, sensor plates, screws are for options.Production of Cam Roller Hollow Rotary Actuators: FAQs about Heavy Duty Hollow Rotary TablesDo hollow tables need a separate brake for heavy cuts? Yes. Cutting torque often exceeds the drive torque. Engage the brake before milling. The brake holds the position rigidly.What cooling method works best for heavy duty hollow tables? Oil circulation cooling works best. Air cooling works for light duty. Water cooling requires sealed bearings.How do I seal the through-hole against coolant ingress? Use a rotating labyrinth seal for Heavy Duty Hollow Rotary Tables. Add an air purge connection. Replace seals every 3000 operating hours.What causes runout at the hollow table face? Dirty mounting surface causes runout. Loose bearing preload nut causes runout. Damaged roller bearing causes runout.Why does my hollow table lose position during milling? The brake may not engage fully. The encoder coupling may slip. The drive belt may stretch. Check each system separately.What material suits a heavy duty hollow table housing? High tensile cast iron absorbs vibration. Ductile iron resists cracking. Aluminum reduces weight but lacks stiffness.How do I clean chips from the hollow bore after machining? Use a nylon brush through the hole of Heavy Duty Hollow Rotary Tables. Blow compressed air from the back side. Never use a metal scraper inside the bore.You are welcome to watch more projects or visit our website to check other series or load down e-catalogues for further technical data.
