Ultimation adds Interroll MDR systems to fast growing 24V MDR range

Ultimation expands as Interroll Distributor

Ultimation has added the Interroll range of 24V MDR (Motor Driven Rollers) conveyors to the line up. Interroll systems can be configured as “ready to run” modules in 10 foot sections, as retrofit kits for existing gravity conveyors and as individual component sets.

Ultimation’s President, Richard Canny, is forecasting that 24 volt conveyor technology will continue to displace older technologies. “Customers love the quiet, energy efficient conveyor systems that motor driven rollers enable. Because the motors only run when the product needs to be moved, the duty cycle of these conveyors is low. Ultimation began designing and building MDR systems about 7 years ago, and we are experiencing fantastic growth in the deployment of the technology. We’ve been working with Interroll for some time now, and we’re now ready to expand as an Interroll distributor and system integrator to offer the full range of their products.”

Conveyor Roller Replacement: What You Need to Know

How to replace conveyor rollers

Gravity conveyors are used in distribution warehouses, assembly lines, and shipping departments throughout the world. With routine maintenance and care to the frames, conveyor rollers, and other parts, a gravity conveyor can last for many years. The rollers in these conveyors can get dirty or damaged, and eventually they need replacement. Thankfully, conveyor rollers are easily replaceable, and doing so will extend the life of the conveying system. Another common situation is there simply needs to be more rollers added to an existing system to help parts move more smoothly along the conveyor when replacing conveyor rollers.

Ultimation marketing specialist, Kali Cresent, explains how to go about the process of gravity conveyor roller replacement. “The best way is to start with the frames first. Before measuring up the rollers, check the size of the frame that the rollers will fit in. This is the single most important measurement.

How to replace gravity rollers

Kali says “Start by measuring the frames first!”



Know exactly the information you need before placing a replacement roller order. Here is Kali’s list of the information Ultimation requires:

1.4" Gravity Conveyor Roller








  • Between Frame (BF) Distance: Measure the frames that the rollers will fit into from one side to the other in inches or mm. Replacement conveyor rollers are often referred to according to the BF (Between Frames) size they are made to e.g. 18″BF Gravity Roller. Common between frame widths are 10″, 15″, 16″, 21″, and 22″
  • Diameter of the roller: Common sizes are 1-3/8″ (1.4″) , 1.9″, 2.5″ and 2-9/16″. It’s tough to measure this with a tape measure, so use a pair of calipers or more precise measuring instrument to ensure you have the right diameter
  • Retention system: In order to fit into the frames, rollers are generally spring loaded on one side. But sometimes rollers have springs on both sides, or use pins through the shaft instead of springs
  • Surface finish: Galvanized (zinc plated) is a common finish, while heavier duty rollers are sometimes mild steel
  • Axle configuration: North American gravity roller conveyors usually have hexagonal axles of 7/16″ or 11/16″ for medium and larger diameter rollers. Smaller rollers typically use a 1/4″ round steel axle. Measure the size of your existing roller axles
  • Grooves or drive system: Rollers may have dual grooves (for O-Ring drive systems), pulleys for ribbed drives or sprockets attached
  • Centers: Measure the center distance from one gravity roller to the next. This will help you calculate how many you need!

How conveyor rollers are assembled

  • Crimped
    •  A crimped gravity conveyor roller has a tube which is crimped down over the bearing to hold it in place. Bearings installed in this
      manner are non-replaceable.
    • Edges of tube are bent towards the center.

  • Press Fit
    • A press fit roller has a tube which is counter bored to the correct inside diameter for the bearing to be press fit into
      place or slip fit for large diameter rollers.

Roller Tube Material alternatives

When replacing conveyor rollers, an important defining factor is the material the conveyor rollers are constructed of. The most common type being galvanized steel as it is cost effective, and resists rust. Other materials include; stainless steel for wet applications and for food preparation, and PVC or polyurethane coated rollers for non-marring applications.

Roller Diameter and Gauge

Roller diameter is determined by measuring the width or outside diameter of your roller. 1-3/8″, 1.9″, and 2-1/2″ diameters are common sizes, but other special sizes exist. Normally standard gauges (wall thickness) are based upon roller diameter. Think about the way the conveyors are used when replacing conveyor rollers. Locations that are loaded by fork lifts or where items are impact loading (dropped), these rollers should have a thicker wall than the rest of the conveyor system, giving it a greater load capacity and strength. Remember, don’t round your measurements, use a precision tool, such as calipers, to measure roller diameter.

Axles and Retention

The axle size is determined by measuring the diameter of a round axle or measuring from flat side to flat side on a hex axle. Common axle sizes are 1/4″ round, 7/16″ and 11/16″ hex axles. Most axles are made from plain steel. The vast majority of axle types are spring retained on one end, but may also be pin retained so that the roller may be locked into place with the use of retaining pins.

  • Identifying Axle Retention
    • Spring Retained
      • Determine the axle retention by pressing one end of the axle in; if the axle pushes in, it is spring retained on the
        opposite end.
      • Repeat this process on the other end of the axle, if the axle reacts the same it is dual spring retained.
      • If the roller has sprockets or grooves it is important to identify which end the spring is on.
    • Pin Retained
      • Pin retained axles will have holes in the ends of the axles to insert the pins. When the pins are removed the axle
        can be removed.
      • Identify the type of pin. Our standard options include the cotter pin and hog pin.

Pin Retention for Conveyor Rollers


    • Not Retained
      • A plain axle will not have any type of retention. No pins or springs will be holding the axle in place.
  • Axle Length

    • For a proper fit, you will also need to know your axle’s overall length and extensions. Use a tape measure to measure from the end of one axle to the other to get overall length, and for axle extension (how far the axle sticks out from the bearing on each end) measure from end of the bearing to the end of the axle. This must be done on both sides as the axle extension might be different on each end. Measure to the nearest 1/32″.


Non-precision bearings are standard for most rollers in conveyor roller replacement projects. These are free rolling bearings and are cost effective. Greased packed bearings are normally used for power conveyor applications or harsh environments. Precision ABEC 1 bearings are used when noise levels are a concern or when the rollers will be required to travel at a high speed.

Over Under Conveyor can maximize use of valuable floor space

Over Under Conveyors (sometime abbreviated to Over-N-Under) are making a comeback, with Ultimation engineering a number of new systems recently. This style of conveyor is a derivative of the overhead chain conveyor family, with one unique difference. Over-Under style chain systems have the main product delivery path underneath, and the chain return path overhead. This over-under style therefore has a very compact footprint. Manufacturing engineers like the over under conveyor design because it enables more productive use of all available floor space.

Over and under conveyor

Gravity, powered, or power and free versions of Over and Under Conveyors

Over and under conveyors can be simple gravity feeding systems where parts move under their on weight downhill to an unload station. More sophisticated systems can be motorized with a drive. And if parts are required to automatically stop, start or accumulate in a buffer situation, then power and free technology can be used. Feeding parts into and out of robot weld or assembly cells is a common application for this style of buffer system.

Fast to integrate with 3D design and Webb Unibilt enclosed track components

Each system that Ultimation engineers starts in a ‘virtual assembly plant’ where customers can visualize the new conveyor system as it is designed and developed in 3D CAD technology. Robot load and reach studies are performed using the digital models, and likewise Ultimation’s team checks that any human interface with the conveyors and parts follows all ergonomic guidelines for safety and ease of use.


Many systems use Jervis Webb Unibilt enclosed track conveyor track and components. Ultimation’s engineers will then perform important Finite Element Analysis (FEA) simulations on any overhead structures and complete any electrical engineering of the systems.

“Customers  really appreciate being able to see their new system in a 3D rendering and digital model before it is produced for them” said Ultimation Project Manager, Mike Herzog. “They can look for any issues with nearby equipment, study how their robots or operators will interface with the conveyor, and optimized their floor space much more easily.”

“Once we build the conveyor, it typically requires less adjustment at the final buy-off stage as the customer knows exactly what they will be receiving.”

The over-under style conveyor has been in use for decades. With today’s modern 3D tools, engineering and building them has become much faster and easier, and they are sure to have a bright future.

Over under power and free conveyor

The actual system built for the customer

The Webb Unibilt component set is ideal for these kind of applications as the chain enables tight turns due the unique design of the chain system which incorporates side guide rollers within the chain. Unibilt is available in hand push style, motorized and power and free. It can be installed in an overhead configuration, inverted or in a combination of overhead and inverted as is the case with these over/under systems.
