What is an indexing system?
Cam indexing systems are integrated transmission solutions that include a cam indexer, a drive motor, a control system, and other parts. The main thing they do is use pre-programmed functions to make workpieces move in precise, intermittent, continuous, or back-and-forth motions. This system goes through pre-factory commissioning (matching mechanical parameters and calibrating electrical signals) before it can be added to the production line. This cuts down on-site commissioning time by 80% compared to self-assembly from purchased parts. The accuracy of interoperability for each part is ±30 arc seconds (about ±0.0083°), which fixes problems like vibration and accuracy loss that happen when parts don't work together.
This technology perfectly coordinates servo motors and cam indexers in pharmaceutical packaging manufacturing lines so that there is no gap between filling, capping, and labeling stations for prescription bottles.
Core advantages of the product
High precision
The standard model has a positioning accuracy of ± 30 arc seconds, the customized model has a positioning accuracy of ± 15 arc seconds, and the internal structural components have a CNC machining accuracy of ± 0.02mm. From the core components to the overall assembly, the accuracy error is strictly controlled throughout the process to avoid vibration and positioning deviation.
Plug and play, deployment efficiency increased by 80%
Complete mechanical parameter matching (motor speed and division frequency adaptation) and electrical signal calibration (reducing signal delay) before leaving the factory, significantly reducing production line downtime compared to separately purchasing components for assembly (requiring 3-5 days of professional debugging).
Multi-scenario adaptation
Cam Indexing Systems supports customized requirements such as high temperature resistance, dust prevention, and waterproofing, and can meet special scenarios such as Class 10000 clean environments for medical devices and high-speed vibration resistance for food packaging.
And the cam and follower are made of high wear-resistant materials, matched with high-quality bearings and sealing design, reducing friction loss, extending equipment service life, and adapting to 24-hour continuous production conditions.

How Cam Indexing Systems Work
The cam indexing system works with a specifically created cam profile interacting with a follower. By regulating the rotation or indexing action, this cam profile generates a start- and stop motion. The basic components and procedure involved are shown below.
Profile Cam
Usually formed in a barrel or globoidal form, the cam's profile is exactly designed to specify the particular movement and dwell times. The form of the cam determines the angle and timing of every index as it turns.
Mechanism for Following Leaders
The follower comes into touch with the surface of the cam. The follower is driven by the cam rotations, which also provide controlled movement. This movement is transferred to the output shaft producing either linear or intermittent rotation.
Shaft of Output and Drive
The design of the cam profile lets the output shaft spin exactly to a designated position and hold (dwell) before advancing to the next position. Task like pausing, processing, and indexing components at designated locations are made possible by this intermittent motion.
Housing and bearings
Inside a house with premium bearings, the cam and follower are surrounded to decrease friction, enable seamless operation, and prolong system lifetime.
How to choose the model of cam indexer
Clarify application requirements
Indexing position: Determine the required number of workstations, that is, the number of Indexing positions of the cam Indexer in each movement.
Indexing angle: Determine the angle of each rotation based on the number of work positions and application requirements.
Input shaft speed: Understanding the speed of the input shaft is an important parameter for calculating the transmission ratio and the life of the Indexer.
Load conditions: Determine the load that needs to be borne, including factors such as load capacity, inertia, and friction.
Application scenario: Consider whether special requirements such as high temperature resistance, dust prevention, and waterproofing are needed.
Calculate the rotation time and dwell time
Indexing time: Determine the time required for the cam to move from one position to the next.
Stay time: Determine the time when the Indexer stops, that is, the time the product needs to stay in one position.
These times are closely related to the working rhythm of the entire system and should be matched with the process requirements.
Select cam curve
Select suitable curves according to application requirements, such as constant velocity motion curve, acceleration deceleration curve, etc., to ensure smooth indexing action, reduce impact, and extend equipment service life.
Determine output torque and inertia
Calculate the torque and load inertia on the output shaft and select the torque level of the Indexer according to the load requirements.
Ensure that the Indexer can withstand the inertia moment of the load to avoid vibration or deviation during equipment operation.
Choose the appropriate model and model
Based on the previously determined parameters, search for models that meet the requirements in the product catalog provided by the manufacturer.
Select the appropriate model and specifications based on the size, installation method, and output shaft requirements of the Indexer.
Consider special needs
If there are special requirements, such as high temperature resistance, dust prevention, waterproofing, etc., they should also be considered when selecting.
Customization requirements need to be communicated with the manufacturer to determine if they can meet special design needs.
Confirm the selection with the manufacturer
Communicate the preliminary selection plan with the manufacturer to confirm whether it meets the requirements and obtain technical support.
Fine tune the parameters according to the actual situation to ensure that the final selection meets the overall requirements of the equipment.

FAQ
Q: What are the benefits of a cam indexing system over buying the motor and indexer separately?
A: The main benefits are "synergistic accuracy" and "deployment efficiency."
In terms of accuracy, factory-matched mechanical parameter matching (for example, matching motor speed with indexing frequency) and electrical signal calibration (which reduces signal latency) lead to a coordinated accuracy of ±30 arc seconds. "Component tolerance accumulation" can easily lower accuracy to less than ±0.02° when parts are put together separately.
When it comes to efficiency, the system is plug-and-play and can be set up in less than two hours on site. It takes 3 to 5 days of professional commissioning to put together the separate parts (this includes matching parameters and fixing signals).
After maintenance, it's also easier.
Q: Do you need professionals to install the system? What are the site requirements?
A: You don't need special people to handle the basic installation (there is a full installation manual and video instruction), but you do need to meet the following:
To keep the system from vibrating as it tilts, the mounting surface must be level to within 0.1 mm/m (checked with a spirit level).
Leave at least 300 mm of space for heat to escape (the motor and controller need air to work).
Stability of the power supply: Voltage changes of less than or equal to 5% (a voltage stabilizer is advised, as otherwise it could damage the accuracy of control).
Q: How long does it take to customize a system for a specific scenario?
A: The procedure and cycle for customizing are usually as follows:
Confirming requirements (1–3 days): Give production line drawings (or do a site study) to make things like load, speed, installation space, and communication protocol clearer. Then make a schematic layout.
Production and commissioning (15–20 days): Make the parts according to the plans and finish pre-commissioning, which includes 72 hours of continuous operation testing.
Delivery: This depends on logistics conditions.
