There are many applications in automation calling for repetitive rotary indexing. Some examples:
There are at least three types of indexing drives that the engineer can choose between for these applications:
Cam drives have been used for many years and are capable of good accuracy and dynamic control, high speed, and heavy loads. They are typically driven by a gearmotor, with one revolution of the input for each incremental motion of the output. They are best suited for continuous indexing which does not require the motor to be started and stopped for each cycle.
PROS:
|
CONS:
|
A servo based indexing drive for such an application will include a servomotor with or without a gearbox, an encoder for position feedback, a motion controller, and an amplifier. Some of these components may be combined into integrated packages. There is normally a system controller overseeing the motion control, including human interface.
PROS:

CONS:

Pneumatic indexing drives, such as our indexing actuators, are simple, mechanical components capable of repetitive rotary indexing with no accumulating error. They are based on rack-and-pinion rotary actuators with the addition of one-way roller clutches and a ratchet and pawl system for stopping and registration. The motion is initiated by a directional control valve, so they are well suited to flexible automation where the index must occur on demand. They are robust and durable, but cannot match the controlled motion characteristics of the servo or cam drives.
PROS:

CONS:
|
The relative amount of energy these drives consume will depend on the duty cycle of the application. Cam and servo drives are both quite efficient but differ in that the servo uses full power to hold the load in place whereas the cam drive uses power only when driving the load. A pneumatic indexer uses compressed air, which is less efficient than an electric motor drive, but also uses no power when in the locked condition. So, if the duty cycle includes a high percentage of dwell time, the advantage shifts toward the cam and pneumatic systems.

Our smallest indexing actuator, the X1 has been redesigned in recent years to increase its load bearing capacity and enhance value-added features such as washdown protection. The unique device indexes with high accuracy and no accumulating error. It is ideal for use in small index tables, conveyors, or to consistently position parts evenly for multiple simultaneous operations.
Specifications:
See the X1 Indexing Actuator Part Number page for detailed configuration and option information.
For double the torque, consider the X12 Indexing Actuator.
If you don't need accurate positioning, consider the S1 Stepping Actuator.
The X12 indexing actuator has been redesigned in recent years to increase its load bearing capacity and enhance value-added features such as washdown protection. This unique device indexes with high accuracy and no accumulating error. It is ideal for use in small index tables, conveyors, or to consistently position parts evenly for multiple simultaneous operations.
Specifications:
See the X12 Indexing Actuator Part Number page for detailed configuration and option information.
For increased torque, consider the X2 Indexing Actuator.
The unique X2 indexing actuator provides great position accuracy and no accumulating error. It is ideal for use in relatively small index tables, conveyors, or to consistently position parts evenly for multiple simultaneous operations. This indexer is not suitable for applications with a load pulling its shaft, instead consider a bigger indexer such as the X3 Indexing Actuator. Washdown protection option is not currently available for this actuator or its dual rack counterpart, the X22.
Specifications:
See the X2 Indexing Actuator Part Numberpage for detailed configuration and option information.
If you don't need accurate positioning, consider the S2 Stepping Actuator.
For added independently-controlled linear motion, select our PX2 Nitpicker Actuator.
The X22 indexing actuator has a precision ground shaft that delivers 73 inch pounds of torque at a max psi of 75 psi. This unique device indexes with high accuracy and no accumulating error. It is ideal for use in relatively small index tables, conveyors, or to consistently position parts evenly for multiple simultaneous operations.
Specifications:
See the X22 Indexing Actuator Part Numberpage for detailed configuration and option information.
If your application features a load that would exert a pull force on the indexer’s shaft or requires washdown protection, consider using an X3 Indexing Actuator instead.
If independently-controlled linear motion is desired, combined with the X22 rotary characteristics, select our PX22 Nitpicker Actuator.
This unique device indexes with high accuracy and no accumulating error. Floating pistons and a precision ground rack riding in replaceable sintered bronze bearings assure millions of reliable cycles. It is ideal for use in index tables, conveyors, or to consistently position parts evenly for multiple simultaneous operations.
Specifications:
See the X3 Indexing Actuator Part Number page for detailed configuration and option information.
For double the torque, see the X32 Indexing Actuator.
If you don't need accurate positioning, consider the S3 Stepping Actuator.
This unique device indexes with high accuracy and no accumulating error. Floating pistons and a precision ground rack riding in replaceable sintered bronze bearings assure millions of reliable duty cycles. It is ideal for use in medium index tables, conveyors, or to consistently position parts evenly for multiple simultaneous operations.
Specifications:
See the X3 Indexing Actuator Part Number page for detailed configuration and option information.
For increased torque, consider the X4 Indexing Actuator.
The X4 is our largest single rack indexing actuator, delivering almost 3.5 inch-pounds of torque per psi of working pressure. This unique device indexes with very high accuracy and no accumulating error. It is ideal for use in index tables, conveyors, or to consistently position parts evenly for multiple simultaneous operations. The X4 is rugged, fast, simple to operate, and very reliable.
Specifications:
See the X4 Indexing Actuator Part Number page for detailed configuration and option information.
For double the torque, see the X42 Indexing Actuator.
If you don't need accurate positioning, consider the S4 Stepping Actuator.

Rotary
Bidirectional rotation between two positions, like a windshield wiper. Our mini, or compact, rotary actuators are designed for applications where space is of the essence and torque is as important.
Multi-position
Multi-position actuators provide back and forth rotation between three, four, or five positions in any sequence. The 3 position is the most common, but 4 or 5 position units give additional flexibility
Indexing
Indexing actuators provide unidirectional rotation in fixed precise steps to hard stops. They prevent backward rotation and feature no accumulating error. Single or dual rack indexers available.
Stepping
Stepping actuators provide unidirectional rotation in steps, like indexing actuators, but without the hard stops. These actuators also prevent backward rotation but incur an accumulating error.
Pick & place
Pick & place actuators combine a rotary section with a linear cylinder to provide independently-controlled linear and rotary motion. As multi-motion actuators, they can also provide stepping motion.
Rotomation welcomes requests for special actuators because we understand how they can save our customers money by reducing cost of extra parts or engineering time and/or improving their product or process.
If your application requires a simple modification to one or more parts on one of our standard units.
If your application requires one of our standard actuator to be made from a different material, including stainless steel, due to specific environmental requirements.
If your application would be optimized by having an actuator designed from the ground up to suit your exact needs.
For over 50 years, Rotomation has been the go-to choice for businesses in need of top-notch actuators and drives to meet their manufacturing requirements. Our success is a direct reflection of our customers' triumphs – by offering them high-quality, rugged products tailored to their exact specifications, we ensure unrivaled reliability.
