Linear Motion Solutions Using T-Slot Aluminum

The shortest path between two points is a straight line. In the automation industry, this is achieved through a linear motion system. Most systems are custom-made with t-slot aluminum profiles along with dynamic components. T-slot provides a level of support, guidance, modularity, and durability that other materials can’t offer. At Parco, we offer a multitude of t-slot and components to help design your linear motion system. We will work with our equipment and our technical partners to assist you in building your industrial linear motion, conveyor or robotic solution that is efficient, lean, and meets your industry requirements.

Linear Motion Foundation and Guides

Typically, you have a mounting surface of base profiles that allows the system to rest on end supports. Guidance is achieved through either ball guides, wheels, or slides/prisms. 

Ball guides: These guides have high stiffness and tend to carry the heaviest loads. These types of guides move with little friction and come in either single or dual rail configurations. 

Wheel guides: Like ball guides, have high stiffness and can travel quickly with low friction. With wheel guides, shock damage is possible. 

Slide or prism guides: These guides run on the profile’s surface with polymer bushings. This allows for quiet motion, and the ability to withstand high shock loads and environments where dirt, oil, dust, or chemicals are present.

Linear Motion Drive Technologies

Belts, leadscrew, and ball-screws are the common drive technologies used in linear motion systems. Below we will explain them further for you. 

Ball-screw Drive  

In a ball-screw drive, ball bearings move along grooves in a threaded shaft, the ball screw, and turn through a ball nut. Since the bearings share the load, ball-screw drives have relatively high thrust capacity. With ball-screw drives and t-slot, there is total accuracy because the profiles are machined precisely to specifications.

Leadscrew Drives

Leadscrew drives cannot match the accuracy of ball-screw drives; however, their quietness and repetition capability are very useful in transport cycles. They are used in low to medium-duty applications that require transport. 

 Belt Drive

For high-throughput transport applications, belt drives are utilized. Their speed and velocity allow them to move quickly. Typical velocity can be measured with belt drives up to 10 meters per sec. Acceleration can go up to 40 meters per second squared. 

Ultimately, you can make various combinations of the above, but not every setup will make sense. Most practical applications will utilize one of the following:

  • Leadscrews driving ball or slide guides 
  • Ball-screws paired with ball or slide guides
  • Belts driving slide, ball or wheel guides

Lubrication and Seals 

Most guide and drive systems will require lubrication. There are several ways to achieve this and reduce preventative maintenance in the future. One way to do this is by incorporating a lubrication system.  As mentioned above, prism guides have a polymer that has inherent lubrication, therefore making them maintenance-free.

Seals are useful with t-slot as they keep lubrication and contaminants out. From magnetic seals to plastic cover bands, sealing technology is easily implemented with t-slot profiles.

Motor Mount Options

With mounting options, it is imperative that the motor housing and coupling mate properly to the motor flange, pilot, and shaft. Most motor dimensions meet NEMA standards, thereby making them easy to mount in any application. 

This essential component can either be stepper, servo, or induction. Different applications will have different motor requirements. For linear actuation, there are two motor mounting options: inline or reverse parallel.

Inline: This mount option allows for the motor to sit in line with the actuator with a spider or rigid coupler and a servo that connects to the actuator’s driveshaft. This mount configuration is longer than the reverse parallel but offers less height.

Reverse Parallel: This mount option has the motor parallel to the actuator and coupled to the actuator drive shaft by way of gears, belts, or pulleys. This mounting option takes up less space than an inline option and provides more flexibility.

  • This was the first time I tried Parco-inc. for one of my t-slot projects. It was easy to find what I needed and order on the website. I got the parts quickly and the quality was great, so I will be buying here from now on!
  • Really good quality aluminum i can feel the difference between it and other parts i ordered from china also the measurements was on point
  • I use ALOT of these little anchor faster, every month. My regular vendor was out of stock, and so I found Parco and ordered from them. The fasteners arrived quickly, we're high quality, and they even worked with me on a bulk discounted price. 10/10 in all areas!!
  • I am a small business and needed the t slot in a hurry. They processed my order, cut to size and shipped in less then 36 hours and 2 days before Christmas. Wonderful customer service. Thank you
  • Just awesome. Great customer service and response to questions, all cuts and pieces exactly like I ordered, extrusions seem like quality, fast shipping, and well packed to protect the items. I can't say enough about the quality and service. Will order again.
