Rotary tables with large hollow bores are precision motion platforms designed for angular positioning while providing an oversized central opening for internal routing and integration.Here we introduce Rotary table large hollow bores from TallMan RoboticsThis rotary table with large hollow bore integrates a central through-hole exceeding 50 mm diameter within the rotating platen and stationary housing. This bore allows passage of shafts, cables, fluids, or optics through the rotation axis. Models such as the TMN feature an 85 mm hollow bore diameter, integrated planetary gearboxes, and optimized motor mounting systems, making them highly versatile for mid-size tables and end-of-arm tooling.Model Selection code of Cam Roller Rotary table large hollow bores: Technical parameters of Cam Roller Rotary table :SeriesCAM roller type Rotary table large hollow boresModelTMW68TMW90TMW115TMW215TMW315TMW415PhotoDesign 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)16kgs2445120200300ModelTMW500TMW600TMW800TMW1100TMW1300TMW1900PhotoDesign load (kgs)≤800kgs≤2 Tons≤ 4Tons≤ 8Tons≤ 15Tons≤30 TonsDiameter of Aperture (mm)60 mm100 mm150mm290mm290mm1100mmIndexing Accuracy(Arc Min)±15Max Face Force/Fa(Nm)7000090000120000200000240000320000Max Radial force/Fr(Nm)350004600070000106000120000190000Max Tilting Torque/Mk(Nm)6500215006000096000100000175000Max Tangential Torque/Ta(Nm)180040008200205002400038000Reduction Ratio (i)Servo indexing: 20/40/60/100,can be customized; Mechanical indexing: 2/4/6/8/10/12/16/24 workstationsMotor in matchingServo motor + reducer/ordinary reducer motor/four series of reducer motorsWeight (kg)300kgs420kgs700kgs1.35 Tons1.5 Tons2.0 Tons 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 Rotary tables: FAQs about Rotary table large hollow boresHow does a hollow bore affect load capacity?Larger bores reduce bearing race diameter. This lowers moment load capacity by 30-50%. Choose a wider bearing to compensate.Can you pass coolant through a hollow bore rotary table?Yes. Install rotary unions on both ends. Use double lip seals to stop leaks. Match seal material to coolant type.What machines need a large hollow bore rotary table?Pipe welding lathes need bores for pipe ends. Fiber winding machines need bores for mandrels. Laser cutters need bores for beam path.Can you retrofit a standard rotary table to hollow bore?No. You would cut through the main bearing race. The table would collapse under load. Buy a purpose-built hollow bore unit.How do you clean the inside of a hollow bore?Push a foam pig through the bore with compressed air. Wipe bearing surfaces with lint-free cloth. Use vacuum for fine particles.
