Product Description
DF Flange Type Indexer
45DF, 60DF, 70DF, 80DF, 110DF, 140DF, 180DF, 250DF
This model is designed for heavy-duty applications, capable of withstanding significant vertical radial or axial pressure.The output shaft features a face-plate design with a flange center, mounting holes on the plate surface, positioning pins, and a wide fixing surface, ensuring excellent flatness, stability, and robust performance. It is most suitable for high-load rotary table driving applications. This series is widely used in various disc-type processing machinery and similar industrial automation equipment requiring intermittent motion, particularly in driving large turntables.
DS Spindle Type Indexer
25DS, 32DS, 38DS, 45DS, 60DS, 63DS, 70DS, 80DS, 83DS, 100DS, 110DS, 125DS, 140DS, 180DS
This series features a classic traditional spindle design. When installing accessories such as gears, couplings, or coupling discs, special attention must be paid to the bore diameter tolerance (+0.015/-0) and keyway tolerance (+0.015/-0). It is commonly used in applications such as conveyor belt drives, gear drives, and backlash-free coupling drives.
DT Platform/Tabletop Type Indexer
Models: 80DT, 110DT, 140DT, 180DT, 210DT, 250DT, 350DT, 450DT
This series shares similar dimensional and functional characteristics with the flange type indexer. During operation, it can withstand exceptionally high axial loads and vertical radial pressure. The output end features a raised mounting surface and a large-diameter hollow shaft, allowing for integration with dynamic or static automation interface equipment. Power, hydraulic, and pneumatic lines can be routed through the hollow bore. This series is widely used in heavy-duty, direct-drive automation equipment across various mechanisms and industrial machinery for synchronous intermittent motion.
DA Ultra-thin Platform/Tabletop Type Indexer
Models: 70DA, 90DA, 110DA, 150DA, 190DA, 230DA, 330DA, 450DA
The design characteristics of the DA series are functionally identical to the DT platform type indexer. It can be equipped with both a rotating plate and a stationary plate. The rotating plate can withstand extremely high axial loads and vertical radial pressure during operation, while the raised output face allows for the installation of a stationary plate. Its large-diameter hollow shaft accommodates dynamic and static automation interface equipment, enabling electrical, hydraulic, and pneumatic lines to be routed internally. This model is widely used in heavy-load, multi-process, and complex product assembly applications, as well as various industrial machines. Its ultra-thin design is suitable for installation in compact spaces, saving equipment layout space.
PU Plate Cam (Parallel Index) Type Indexer
Models: PU50DS, PU60DS, PU65DS, PU80DS, PU100DS, PU125DS, PU150DS, PU175DS, PU225DS, PU250DS, PU320DS
This series incorporates two plate cams fixed to the input shaft and a roller-turret output shaft driven by the cams. It utilizes a parallel conjugate cam mechanism design, where the rotation of the two plate cams mounted on the input shaft drives the roller turret to rotate, achieving precise indexing of the output shaft. It is most suitable for driving conveyor belts with large pitch distances or applications requiring longer dwell times during intermittent indexing. Additionally, a three-plate heavy-duty variant is available, which is better suited for high-speed, long-pitch conveying applications and offers even longer dwell times compared to the two-plate design.

Installation of Input Shaft and Output Shaft
Fixing methods for the output shaft: For couplings, pulleys, sprockets, turntables, etc., the following fixing methods are available:
• 1. Dowel pin 2. Fixed wrench 3. Fixed indexer flange face
• Fixing of the input shaft: If the input shaft cannot rotate smoothly, torque overload, machine vibration, and abnormal noise will occur, leading to faults.
• Overload protection: To avoid accidents and damage to the indexer and improve safety, it is necessary to install an overload protection device, which can be mounted on the input shaft or output shaft with an appropriate torque setting.
• The worktable is fixed on the output shaft flange face, subjecting the output shaft to axial load. When the worktable is large, requires high rotation accuracy, or bears an eccentric load, designing an axial load support under the worktable can improve the operational stability of the cam indexer.
