How Carry and Return Rollers are Utilised in a Conveyor System
Conveyor rollers either sit in the bed of an idler frame to support the belt and product or are individually attached under the conveyor to support the belt return. Return Rollers are often specified as flat steel or fitted with Rubber Disc rings under the conveyor on the return section to support the return side of the conveyor belt from distorting with gravity. These rollers turn freely, working in line with the belt in the roller support frame mechanism.
Most high capacity belt conveyors use rollers attached to a troughed idler frame that is mounted under the carrying side of the system. The idler frame can be a single or a multiple set of rollers but are usually comprised of three rollers of equal length. The middle roller is mounted horizontally while the outer two are typically mounted on standard fit for purpose angles to support the base and sides of the belt and the angle or situation. This framing then forms a ‘U’ shape and provides support to the belt sides as it cradles the conveyed material.
ASC Rollers: Premium Quality and Worth the Investment
The initial outlay for a roller, as well as the whole idler frame can be quite substantial. However, you should consider the entire service life of this important componentry in line with your operating system outlay.
Each time a roller or idler system needs to be serviced or replaced, this cost can potentially be substantial, as the conveyor system needs to be completely isolated and shut down. A new roller might need to be purchased and the old one disposed of or recommissioned. In this instance, we recommend purchasing a quality and reliable product that will last for a longer period of time in order to receive better longer term value and possibly have a roller in reserve to minimise down time.
All State Conveyors are able to help reduce the total roller cost by working with your site operation synergies and processes. We are able to assess your operating site conditions so that our rollers are not over or under engineered, ensuring that we maximise your running efficiencies and minimise power consumption.
8 Things to Consider When Selecting Rollers for Your Conveyor System
Eight key considerations that should be reflected upon to ensure that the selected rollers can perform to their maximum operating performance for your conveyor and avoid system breakdowns such as bearing failures due to excessive shaft deflection:
- The size, shape, weight and surface of your conveyed materials
- The operating environment conditions, such as impact, duty, cycle and spacing
- The belt width, roller type and travel speed when choosing the right roller length and diameter
- Shaft diameters must be large enough to support the load and mitigate deflection
- Provides for vibration-free running
- Seals must prevent internal penetration of contaminates such as dirt and water to the bearings
- Select rollers which, are designed and built with labyrinth sealing systems.
- Utilise pre-lubricated precision ball bearings
All State Conveyors in-house custom manufacturing also offers durable lagging solutions for your steel head, tail,snub or bend roller with hot or cold vulcanised rubber as well as being finished with crowning and lagging thicknesses to meet your specified design. Our vast array of stock ensures prompt delivery to you each and every time.
See below for our range of idlers and rollers for your conveyor application.
ASC High Performance Idler and Roller Selection
All State Conveyors stock an extensive range of high performance and durable rollers and idlers for both flat and trough conveyor frames, as well as impact, return and tracking types. Fixed troughed roller frames are supplied as inline or offset with Flat or Rubber Disc Return and Impact roller sets also available.
Offset Vs Inline Idlers
Offset Idlers: Offset idlers have slightly overlapping rollers. They contribute self training properties and must be installed in the correct orientation which is square to the belt and conveyor frame. The moving belt must be in contact with the centre roller first.
Inline Idlers: Inline idlers are generally used on long conveyors and where thick belts are used. They must be installed square to the belt and conveyor frame.

Impact Rollers: For Absorbing Extreme Impact in the Loading Zone
Conveyor Impact Trough Rollers are designed to work best in the product loading zone of a conveyor, providing additional protection by absorbing compression shock to the conveyor belt and the roller frame. Quality Impact rollers will protect the belt where the lump size, weight or shape, exacerbate damage to the belt cover from the free fall of material.
The Impact Roller construction consists of a series of resilient rubber discs assembled onto the steel tube. The rubber discs are designed to absorb the actual impact and have been manufactured with excellent anti-wear characteristics.
Benefits of Impact Rollers:
- Ideal for areas of high impact loads
- Ideal for heavy conveyor loading and transfer points
- Protects the belt where the impact load can cause damage to the belt cover and carcasses
All State Conveyors rubber disc impact rollers are a highly effective way to subdue abrupt and large impact loads and subsequently increase the life span of the roller and support frame used in the impact zone, such as loading and transfer points. We highly recommended to use of Impact Rollers to absorb the contact collision of material free fall.

Rubber Disc Return Rollers (RDRT): Lower Drive Energy and Prevent Carry Back Issues
Rubber Disc Return Rollers (RDRT) are designed to be used on belt return system for situations that have dirty belt environmental conditions and carry back issues. Rubber discs can break up the contact between the belt and the roller surface area reducing the drive energy required and encourages any unwanted return material that might be adhered to the belt to loosen and fall away.
RDRT Rollers Provide a Simple and Cost Effective Solution to Build Up Reduction
All State Conveyors supply return rollers that are specifically used on the return side of the conveyor. Plain flat steel is usually suggested however, rubber disc return rollers (RDRT) can be implemented to break the contact between the belt and the roller surfaces with the rotation of the discs to reduce sticky and caked materials adhering to the return belt.
Our highly effective Rubber Disc Return Rollers are a reliable, simple and cost-effective maintenance solution for this common conveyor belt caking problem. These rollers are ideal for areas where return rollers are subject to high carry back volumes and where return rollers in particular are subjected to high shell wearing. Our rubber discs return rollers are lubricated and then sealed for maximum life which simply eliminates the need for on-going lubrication. Set out should ideally have a distance between them of 2 and 6 metres.
