When choosing a robotic gripper for your automation needs, your best choice all depends on your application. There are a range of End of Arm Tooling (EOAT) devices that may work for your process, but that doesn’t mean that every tool will be the most advantageous.

At RAD, our complete line of grippers covers all your automation specifications. No matter what your needs are, we have the make and model to meet them with our industry-leading products. All of our grippers are designed with maximum durability to last.

We offer 2-jaw, 3-jaw, and collet robotic grippers for your applications. But what are the different uses for these grippers and their particular features?

2-Jaw Grippers: Best for Consistent Processes 

2 Jaw GripperExcellent for items with flat surfaces, 2-jaw grippers are an affordable, dependable choice that work with a wide range of applications. Our 2-jaw parallel grippers are incredibly versatile and we have models designed for use in dirty or harsh environments.

With two points providing even pressure on the item for increased stability, 2-jaw grippers are best for parts that are all similarly sized. However, 2-jaw grippers may not be your ideal choice for fragile items.

With adapter plates for easy installation, 2-jaw grippers can be customized for your manufacturing process, whether you need to grip items from the side or top.

3-Jaw Grippers: For Larger or Irregular Parts

3 Jaw GripperDesigned to carry larger objects than 2-jaw grippers, 3-jaw grippers do well with irregularly-shaped parts, as the three points that touch the part self-adjust to the shape. It’s important to know that 3-jaw grippers can only grip parts axially, and they put even pressure on each point for increased stability.

With better centering and a secure grip, 3-jaw grippers provide accurate performance and can be great options for cylindrical or even surfaces. Like 2-jaw grippers, be cautious when choosing these for delicate parts.

All of our 3-jaw grippers at RAD work well in harsh environments and are one of our most popular designs for a variety of automation processes!

Collet Grippers: Best for Delicate or Similarly-Sized Parts

GripperCollet grippers deliver high-speed performance for parts of consistent shape and size. Providing 360 contact with even pressure, these robotic grippers are an excellent choice for delicate parts.

Adjustable to fit different-sized parts for various applications, collet grippers provide flexibility, but are ideal for parts that have tight tolerances. Easy to change out for maintenance and even field reparable, collet grippers can help reduce downtime.

With their centering capabilities, collet grippers are also an excellent EOAT device for deburring parts or polishing parts. Collet grippers can also work well with cylindrical parts, just as long as part shape and size are consistent.

Why RAD?

At RAD, our robotic grippers are designed to outperform and outlast. You won’t have to change your gripper for many years, even if it’s operating in a challenging environment.

We have a model to fit your specific automation process, and we never receive returns or complaints because our products deliver maximum performance and longevity. We also offer a two-day lead time on orders, which you won’t find anywhere else.

A robotic collet gripper is a tool designed to attach to your robot to transport products in your automation line. With a robotic collet gripper, you can automate processes that include gripping parts that are identical in size.

The collet will open and extend to grab the item and then close and retract to move it. By automating your transport processes for items with a collet gripper, you can prevent damage to your materials and increase your manufacturing efficiency!

Benefits of Using a Robotic Collet Gripper

There are many benefits of using a robotic collet gripper for the proper applications. These grippers:

  • Work quickly. Since they have a high clamping force, collet grippers can rapidly perform their task, allowing you to increase productivity.

  • Center parts. Their centering capabilities allow you to use collet grippers for deburring or polishing parts for safety and efficiency.

  • Perform optimal gripping. Collet grippers use 360-degree contact on your item, which provides even pressure to prevent damage to even the most delicate parts.

  • Have a narrow profile. This allows the gripper to reach for items in constricted areas where materials may be crowded together.

  • Are adjustable. You’re able to pneumatically adjust the collet’s gripping force, which means you can adapt the gripper to function with different parts. They’re also flexible enough to give you hundreds of different sizes for different parts.

  • Maintain durability. Its aluminum casing keeps the tool light while the collets and brushings are made of durable steel.

Robotic collet grippers from RAD are also easy to change out, allowing you to quickly swap out a gripper for maintenance or repairs to keep your automation processes up and running.

Our collet grippers can also be repaired in the field to reduce downtime, and should you ever need a replacement part, we can usually ship items that same day to help you get your replacement component as soon as possible.

Are There Customizations for Collet Grippers for My Application?

You can easily customize collet grippers to suit your particular application. For example, for those who need collet grippers for harsh environments, we offer Viton seals, which help your gripper resist damage from corrosive fluids and high temperatures.

Other customizations include adapter plates for easy installation, collision sensors to protect your investment, and tool changers so that your robot can perform different operations without the need for you to manually swap out tools.

With customizations for your collet grippers, you can ensure your robot tooling is perfectly adapted to your environment for maximum performance.

When to Consider a Robotic Collet Gripper

Robotic collet grippers are excellent for a variety of applications. However, since they’re designed for parts with particular dimensions, these grippers are best used for:

  • Parts that are all the same size

  • Items that have tight tolerances

  • Parts with cylindrical surfaces

  • Holding items that need to be polished, grinded, or deburred

If you’re not sure whether or not a collet gripper would be the ideal fit for your particular application, our team at RAD can help you discover if these grippers are the best choice for you!
